73) Briefly describe the four components of a database system.

Answer: The components of a database system are: (1) the users, (2) the application programs, (3) the DBMS, and (4) the database. The users are the people that will employ the system to input data, modify existing data, and delete data in order to perform their jobs. The application programs are computer programs that act as intermediaries between the users and the DBMS. The application programs produce forms, reports, and queries; they also translate user actions into data management requests for the DBMS. The DBMS manipulates the database. It receives data management requests from the computer applications and translates them into read and write commands for the database. The database contains the actual user data that the users need to perform their jobs.

Diff: 2 Page Ref: 17-21 AACSB: Information Technology Chapter Obj.: Know the components of a database system.

Classification: Concept 74) What components are included in a database?

Answer: The database contains user data, metadata, indexes and other overhead data, and application metadata. User data is the data from the users' environment that they want to track.

Metadata is data about the structure of the database. Indexes and other overhead data are structures that the database uses to improve performance. Finally, the application metadata is data about forms, reports, and other application components that some databases, particularly those created with desktop DBMS products, store with the database.

Diff: 2 Page Ref: 18 AACSB: Information Technology Chapter Obj.: Know the components of a database system.

Classification: Concept 75) What is "metadata," and how does it relate to the definition of a database?

Answer: Metadata is data about the structure of the database itself. This includes data about the names of all the tables in the database, the names of all the columns in each of the tables, the data type of each column in each table, the properties of the tables and the columns, etc. Metadata accounts for the "self-describing" aspect of the definition of a database as a "self-describing collection of integrated tables."

Classification: Concept

15 .

76) Briefly describe the function of the DBMS in a database system.

Answer: The DBMS creates the database and the tables and structures within it. The DBMS also reads and updates the database data. It receives requests from application programs to perform data maintenance tasks. These requests are translated into actions that are performed on the database. In addition to maintaining the user data within the database, the DBMS also maintains the database structures. The DBMS also enforces any rules that have been defined to govern the values of the data, such as data type requirements and referential integrity constraints.

The DBMS controls concurrency issues, which deal with the unwanted interruption of one user's work by another user's work. As the only point of entry into the database, the DBMS also provides security for the database to restrict users' access to only the data that they have authority to read or modify. Finally, the DBMS is responsible for the creation of backup copies of the database data and for restoring the database in case a recovery is required.

Diff: 2 Page Ref: 18 AACSB: Information Technology Chapter Obj.: Learn the purpose of a database management system (DBMS).

Classification: Concept 77) What are "referential integrity constraints"? Give an example.

Answer: A referential integrity constraint is a rule that restricts certain actions on the database data. A referential integrity constraint is used to ensure that the values in a field in one table have matching values in a corresponding field in another table. These constraints are enforced by the DBMS, which will not allow changes to the values of the database that would result in violations of this rule. For example, a database has an EMPLOYEE table and a VEHICLE table that are used to store data on employees and the vehicles that they are assigned to drive. The EMPLOYEE table has a column called EmployeeID that is used to distinguish one employee record from another. The VEHICLE table also has an EmployeeID column that is used to associate a vehicle with the appropriate employee. A referential integrity constraint could be used to prevent a vehicle from being assigned to an employee with an EmployeeID that does not appear in the EMPLOYEE table by requiring that all values in EmployeeID in the VEHICLE table have a matching value in EmployeeID in the EMPLOYEE table.

Classification: Concept

16 .

78) Briefly describe the function of an application program in a database system.

Answer: The application program is responsible for creating and processing forms. The application displays the form to the user, allows the user to complete the data entry, evaluates the form to determine which data management tasks need to be performed, and transmits the appropriate requests to the DBMS. The application creates and transmits queries. The queries are requests for data that are created in a language like SQL, and transmitted to the DBMS to have the requested data returned to the application program. The application also creates and processes reports. The query to retrieve the necessary data for the report is sent to the DBMS. When the DBMS returns the needed data, the application manipulates it as necessary to create the requested report. The application program also applies application logic to control the manipulation of data in accordance with the business rules. Finally, the application program is responsible for providing control. Control must be exercised to allow the users to make choices for functions and tasks as appropriate for their jobs. Also, control must be exercised to manage the activities of the DBMS. Diff: 2 Page Ref: 20-23 AACSB: Information Technology Chapter Obj.: Learn the purpose of a database management system (DBMS).

Classification: Concept 79) What are the advantages and disadvantages of personal DBMS products hiding the complexity of database systems?

Answer: The advantage of hiding the complexity of database systems is that it makes database systems easier for novices to create. Using the graphical tools and wizards of a desktop DBMS product, databases and application programs can be created without developing much database expertise. The disadvantage of hiding the complexity is that the developer does not understand what the desktop DBMS product is doing on the developer's behalf. This limits the developer's ability to create systems with functions not anticipated by the DBMS design team. Further, the developer is limited in their ability to develop systems on a larger scale.

Classification: Concept 80) Microsoft Access is considered a "personal database" product. What is a personal database?

Answer: A personal database combines a DBMS with an application generator. The DBMS performs the functions expected of a DBMS such as database creation, processing, and administration. The application generator adds the ability to create and store forms, reports and queries, as well as some other application-related functions.

Classification: Concept 82) What problems with storing data on two themes in a list are addressed by database technology?

Answer: First, data updates are simplified because the number of updates is reduced when data appears in more than one location in the list. Second, the possibility of incorrectly entering duplicate data is reduced. Third, the problem of inconsistently entering data values is removed.

Finally, the ability to enter data on one theme in the list without having data for the other theme is enhanced.

94) Explain the two basic ways to implement hypervisors.

Answer: There are two basic ways to implement hypervisors. The first is the "bare metal," or type 1 hypervisor shown in Figure 1-35(a). These are loaded into memory, or "booted," before any other programs. Thus, the hypervisor has direct control over the hardware and provides the illusion to virtual machines that they are running on the physical hardware. Type 1 hypervisors are typically used in large data centers. Type 2, or "hosted," hypervisors, as shown in Figure 135(b), are typically used by students or other computer users to run multiple operating systems as regular applications on their desktop or laptop computer.

Answer: Both the primary key and a candidate key can uniquely identify the rows in a table.

The primary key is the candidate key that is chosen by the database designer, working with the users, to uniquely identify rows and to represent relationships. Although any candidate key could, by definition, be selected to act as the primary key, the choice of primary key is often based on design decisions such as the amount of foreign key data that would be generated.

83) Explain the concept of a surrogate key.

Answer: A surrogate key is an artificial key that is created to act as the primary key for a relation. The surrogate key is a unique, numeric value that is appended to the relation. Surrogate keys are used in situations when no suitable primary key exists within the user data, or when all available primary keys within the data are too cumbersome for an efficient design. Surrogate key values have no meaning to the users and are normally hidden on all forms, reports, and displays.

Most DBMS products have the ability to automatically generate values for surrogate keys as needed.

Classification: Concept 84) What is normalization?

Answer: Normalization is a process whereby relations that are not well-formed are modified to become well-formed relations. A relation is considered to be well-formed if the data within it are not subject to unintended negative consequences when it is maintained. Although normalization recognizes several different normal forms, which are categories that the structure of a relation can be classified into based on the types of problems to which it is vulnerable, the basic premises of normalization are that (1) every determinant should be a candidate key, and (2) any relation that is not well formed should be broken into two or more relations that are well-formed.

Diff: 2 Page Ref: 104-117 AACSB: Information Technology Chapter Obj.: Understand normalization and learn a process for normalizing relations.

Classification: Concept 85) What are the basic steps of the normalization process?

Answer: Before starting the normalization process, the relation must be in first normal form, which means that it meets the basic requirements of being a relation. The first step of the normalization process is to identify all the candidate keys in the relation. The second step is to identify all the functional dependencies in the relation. Third, check to see if all the identified determinants are candidate keys. If all determinants are candidate keys, the relation is wellformed and nothing more needs to be done. On the other hand, if any of the determinants is not a candidate key, the relation is not well-formed, and it is necessary to: (1) place the columns of that functional dependency into a new relation, (2) make the determinant of that functional dependency the primary key of the new relation, (3) leave a copy of the determinant in the original relation as a foreign key, and (4) create a referential integrity constraint between the original relation and the new relation. This process should be repeated for every relation until every determinant in a relation is a candidate key of that relation.

86) What is a multivalued dependency, and how do they affect the normalization process?

Answer: A multivalued dependency is the case where a determinant is associated with a set of values. When isolated, they do not have modification anomalies; tables with these isolated dependencies are considered to be in fourth normal form (4NF).

Classification: Concept 87) Explain the concept of a foreign key.

Answer: To implement a relationship within a relational database, the primary key of one relation is placed as an attribute in another relation. This attribute is called a foreign key in the second relation because it is the primary key of a relation that is foreign to the table in which the field resides.

Classification: Concept 88) Explain how to create a relationship in Microsoft Access.

Answer: In Microsoft Access, relationships are created in the Relationships window, which is opened by using the Relationships button on the Database Tools command tab. Once the Relationships window is open, the needed database tables are displayed using the Show Table dialog box. A relationship is initiated by dragging the primary key of one table and dropping it on top of the corresponding foreign key in the related table. At this point the Edit Relationships dialog box is displayed. A referential integrity constraint can be set in this box by checking the Enforce Referential Integrity check box. The relationship is actually created by clicking the Create button in the Edit Relationships dialog box.

Answer: For a table to be considered a relation, it must meet several requirements. First, every cell must contain a single value. Second, there can be no duplicate rows. Third, each column must have a unique name. Fourth, the order of the columns must have no significance. Fifth, all values for a given column must be of the same type. Finally, the order of the rows must have no significance.

90) In practice, why would tables that have duplicate rows be allowed?

Answer: It is not uncommon for a table that is returned as the result of a data manipulation operation, such as a query, to contain duplicate rows. This is often tolerated because of the processing time necessary for the DBMS to search the table to find and eliminate duplicate rows.

This is especially true if the table is very large. In these cases, it is often acceptable to allow the duplicate rows to exist.

89) What are SQL Built-in Functions?

Answer: SQL Built-in Functions are functions that manipulate the results of an SQL SELECT statement. The built-in functions for standard SQL are COUNT, SUM, AVG, MAX, and MIN. The COUNT function counts the number of rows in the result. The SUM function totals the values in a number-oriented field. The AVG function calculates the mean of the values in a number-oriented field. The MAX function determines the highest value, and the MIN function determines the lowest value, in a number-oriented field.

92) Explain the essential format of the CREATE TABLE statement.

Answer: The essential format for the CREATE TABLE statement is: CREATE TABLE tablename ( column-definition, column-definition, column-definition, ... optional table constraints ); "Tablename" is the name that will be given to the newly created table. "Column-definition" is a three-part definition of each column to appear in the table. This definition includes the name of the column, the column's data type, and an optional column constraint (either Primary Key, Null, or Not Null), in that order. The CONSTRAINT phrase can be used to set optional primary key, foreign key and referential integrity constraints for the table. All SQL statements must end with a semi-colon (;).

Classification: Concept 93) Discuss SQL data types.

Answer: Common examples of standard SQL data types are Char, VarChar, Integer, and Numeric. The Char data type is for fixed-length character data. VarChar is for variable-length character data. Integer is for numeric data that are whole numbers only. Numeric is for numeric data that may include decimals. Char, VarChar, and Numeric must be qualified by a length specification to indicate the amount of storage space to be allocated for each data item. For example, Char(10) indicates fixed-length character data that is always stored as 10 characters.

Diff: 1 Page Ref: 161 AACSB: Information Technology Chapter Obj.: Learn basic SQL statements for creating database structures.

Classification: Concept

21 .

94) Distinguish between Char and VarChar data types.

Answer: Char data type is fixed length, so that no matter what the actual length of the data entered is, it will always take exactly the same storage space. For example, Char(10) indicates that 10 characters will always be stored for each value of that column. If the actual data entered is less than the specified fixed length, the data will be padded with blanks. VarChar data type is variable length so that only the amount of space actually needed to store the data is used.

Although VarChar may be more efficient in its use of space, it is not always preferred. VarChar requires the storage of some extra data to indicate the length of the data values, plus it requires some extra processing by the DBMS to arrange the variable length data.

For the primary key attribute, the column property is specified to be PRIMARY KEY. There can be only one attribute specified as PRIMARY KEY with the CREATE TABLE column description method.

This means that the creation of a composite key requires the use of the CONSTRAINT phrase method. Defining a primary key using the CONSTRAINT phrase requires that the column or columns that will serve as the primary key must have been defined as NOT NULL. Using the CONSTRAINT phrase method, the primary key is defined by adding a constraint to the table using a CONSTRAINT phrase after the table columns have been defined. The CONSTRAINT phrase names the column or columns that will be the table's primary key. The structure of the CONSTRAINT phrase is: CONSTRAINT ConstraintName PRIMARY KEY (column names) Diff: 3 Page Ref: 167 AACSB: Information Technology Chapter Obj.: Learn basic SQL statements for creating database structures.

97) Compare and contrast subqueries and joins.

Answer: Subqueries and joins are both used to process data for queries that require data from multiple tables. Subqueries involve embedding a second query within the WHERE clause of the first query. Many levels of subqueries can exist. Joins involve combining the rows of multiple tables into a single relation whose rows contain the data from all the tables that are joined. This new relation can then be processed by the other clauses of the SELECT query. One notable issue with subqueries is that only data from a single table may appear in the result that is returned by the query. One notable issue with joins is that any unmatched rows in either table will not appear in the result that is returned by the query.

Classification: Concept 83) Explain the ambiguity in the broad definition of a weak entity.

Answer: The broad definition of a weak entity includes any entity that relies on another entity for its existence in the database. This is ambiguous since this definition can apply to any entity that is involved in a relationship with a minimum cardinality of 1. If the minimum cardinality is 1, then an entity instance in that entity class cannot exist in the database unless there is a related entity instance in the associated entity class. The more restrictive definition of a weak entity indicates that an entity is weak if it logically depends on the other entity for its existence.

72) Explain the representation of a one-to-many strong entity relationship in a relational database design.

Answer: One-to-many relationships are represented by placing the primary key of the table on the one side of the relationship into the table on the many side of the relationship as a foreign key. The term "parent" refers to the table on the one side of a 1:N relationship, and the term "child" refers to the table on the many side of the 1:N relationship. Therefore, the rule for representing a one-to-many relationship can be summarized as "Place the key of the parent table in the child table as a foreign key."

Classification: Concept 73) Explain the representation of a many-to-many strong entity relationship in a relational database design.

Answer: Many-to-many relationships cannot be directly represented in a relational database design. Therefore, many-to-many relationships are essentially broken into two one-to-many relationships by creating an intersection table that represents the relationship itself. The intersection table takes its key as a combination of the keys of the two original, or parent, entities. Each of the parent entities has a one-to-many relationship with the intersection table that is represented by placing the keys of the parents into the intersection table.

Classification: Concept 74) What is an association relationship, and how does it differ from an N:M relationship?

Answer: An association relationship is very similar to an N:M relationship except that the intersection table has attributes of its own. This means that in addition to the foreign key fields linking to the two strong entities, there is at least one additional field in what would otherwise be called the intersection table but is now an association table. For example, the intersection table ENROLLMENT for STUDENT and CLASS showing student enrollment in each class would normally have two columns: StudentID and ClassID. However, we can turn this intersection table into an association table by adding the column Grade, which records each student's grade in each class.

75) How are 1:1, 1:N and N:M relationships handled in Microsoft Access?

Answer: By default, when Microsoft Access creates a relationship between two tables, it creates a 1:N relationship. N:M relationships are created in Microsoft Access, as in all other DBMS products, as two 1:N relationships linking the two tables (based on the original two entities) through an intersection table. As far as Microsoft Access is concerned, there are no N:M relationships! To create a 1:1 relationship between two tables in Microsoft Access, the Indexed property of the foreign key column in the table containing the foreign key must be set to Yes (No Duplicates) before the relationship is created. With the property set, the relation is automatically created as a 1:1 relationship.

Classification: Concept 76) How are one-to-one recursive relationships addressed using the relational model?

Answer: One-to-one recursive relationships are addressed just the same as one-to-one nonrecursive relationships. The only difference is that both of the related entity instances are in the same entity class. The key of either instance is placed in the other instance as a foreign key.

In the case of a recursive relationship, this means that a new attribute is added to the entity class with the recursive relationship. For each instance, this new attribute will contain the value of the key attribute of the instance that is related.

Classification: Concept 77) Explain the representation of ID-dependent weak entities using the relational model.

Answer: A weak entity is represented in the relational model similarly to the representation of a strong entity. First, a relation is defined for the entity. Each attribute in the weak entity becomes a column in the relation. The primary key of the strong entity on which the weak entity is IDdependent is added to the relation and is made a part of the primary key of the weak entity's relation along with the weak entity's identifier. Finally, the relation is evaluated according to the normalization criteria, and any necessary design changes are made to normalize the relation.

78) Explain the process of representing an entity using the relational model.

Answer: To represent an entity using the relational model, first define a relation for the entity.

The name of the entity is the name of the relation. Each attribute in the entity becomes a column in the relation. If the entity had a unique identifier that would make an appropriate primary key, then that attribute is made the key. If there is no such attribute, then the development team discusses identifiers with the users to determine if an acceptable key attribute exists. If not, then a surrogate key may be used. Finally, the relation is evaluated against the normalization criteria.

Changes to the design may be necessary to satisfy the normalization requirements.

Diff: 2 Page Ref: 368 AACSB: Information Technology Chapter Obj.: Learn how to transform E-R data models into relational designs.

Classification: Concept 79) Explain the pragmatic reason for using surrogate keys.

Answer: Primary keys are commonly included in indexes and are used to identify records to be retrieved by users. The ideal primary key is short, numeric and fixed. When the primary key contains a lengthy text field, this creates a large amount of duplicated data that must be frequently manipulated. For these reasons, it is often practical to use a surrogate key that is generated by the system and is relatively small and easy to manipulate.

81) What is denormalization and why can it be desirable?

Answer: Denormalization is the process of consolidating relations that are in a higher normal form into a single relation that is in a lower normal form, thereby making it susceptible to more anomalies. Denormalization can be desirable for two reasons. First, sometimes the act of normalizing a table can cause it to become too cumbersome or contrived, which makes it difficult to work with. Therefore, denormalization may be preferable when the dangers of the additional anomalies are considered to be of less importance than the ease of working with the relations. Second, processing multiple tables requires more processing overhead than processing a single table. Therefore, performance can often be improved by using a single, denormalized table than multiple, normalized tables. When the performance gain outweighs the dangers of the additional anomalies, the denormalized table may be preferred.

73) Explain the process of using optimistic locking.

Answer: Optimistic locking makes the assumption that no conflicts will occur. Data is read, the transaction is processed, updates are issued, and then a check is made to see if a conflict occurred. If a conflict does occur, the transaction is repeated until it completes without a conflict.

Thus, the lock is not secured until the transaction is completed. This reduces the amount of time that the lock is held.

Read Uncommitted is the least restrictive, and it produces reads that are susceptible to dirty reads, nonrepeatable reads, and phantom reads. Read Committed isolation prevents dirty reads by only reading committed changes. Repeatable Read isolation prevents dirty reads and nonrepeatable reads. Serializable is the most restrictive level of isolation, and it prevents dirty reads, nonrepeatable reads, and phantom reads.

Answer: Two-phased locking is a strategy to ensure the serializability of transactions. A transaction is allowed to obtain locks as necessary, but once the first lock is released, no other locks may be obtained. This produces the two-phased effect-the growing phase in which locks are obtained and the shrinking phase as locks are released.

Answer: The three problems that can occur because of concurrent processing are dirty reads, nonrepeatable reads, and phantom reads. A dirty read occurs when a transaction reads a changed record that has not been committed to the database. If the change is canceled before it is committed, then the read will contain incorrect data. A nonrepeatable read occurs when a transaction rereads data and finds modifications or deletions caused by another transaction. A phantom read occurs when a transaction rereads data and finds new rows that were inserted by another transaction since the prior read.

What is an SQL view, and what is it used for? Include an example based on the CUSTOMER table of the General Sales Database.

Answer: An SQL view is a virtual table constructed from database tables or other views. It is based on the SQL CREATE VIEW command and uses the SQL SELECT statement to construct the view. However, the ORDER BY clause cannot be used when creating a view. For example: CREATE VIEW CustomerNameOnly AS SELECT CustName FROM CUSTOMER; A view may be used to (1) hide columns or rows, (2) show the results of computations, (3) hide complicated SQL syntax, and (4) layer built-in functions.

Diff: 2 Page Ref: B30-B-38 AACSB: Information Technology Chapter Obj.: To use SQL statements to create and use SQL views Classification: Concept 79) What are SQL stored procedures and how are they used?

Answer: An SQL stored procedure is a stored program that is attached to a database instead of just a table or view. Stored procedures can receive input parameters and return results. They can be executed by any process that has permission with the database to use stored procedures. They can issue SELECT, INSERT, UPDATE and DELETE commands. They are typically used by (1) database administrators to do common administrative tasks, and (2) database applications.

84) What are SQL triggers and how are they used?

Answer: An SQL trigger is a stored program that is attached to a table or view. The trigger is invoked by the DBMS whenever an insert, update or delete request is made on the table or view with the trigger. There are three commonly used triggers: BEFORE, INSTEAD OF, and AFTER (MS SQL server does not support BEFORE). This creates a set of nine possible trigger types: BEFORE + [INSERT or UPDATE or DELETE], INSTEAD OF + [INSERT or UPDATE or DELETE], and AFTER + [INSERT or UPDATE or DELETE]. Triggers are used (among other things) for (1) providing default values, (2) validity checking, (3) updating views, and (4) enforcing referential integrity actions.

Reporting systems are used to filter data, sort data, group data, and make simple calculations based on the data. These systems summarize the current status of business activities and compare the current status to past or predicted results. They are also used to classify entities such as customers, employees, products, etc. Report delivery is a critical aspect of reporting systems.

98) What are the elements of a graph database?

Answer: Based on mathematical graph theory, graph databases are composed of nodes, properties, and edges. Nodes are equivalent to entities in E-R data modeling and tables (or relations) in database design. They represent the things that we want to keep track of or about which we want to store data. Properties are equivalent to attributes in E-R data modeling and columns (or fields) in database design. They represent the data items that we want to store for each node. Edges are similar to, but not identical to, the relationships in E-R data models and database designs. They are similar because they connect nodes as relationships connect entities, but they are different because they also store data. Edges can be one-way or two-way.

Diff: 2 Page Ref: C-21 AACSB: Information Technology Chapter Obj.: Learn the basic concepts of the four types of NoSQL database: key-value, column family, graph, and document Classification: Concept 99) What is an XML DTD? Answer: An XML DTD is a Document Type Declaration. A DTD is the first section of an XML document, while the document data itself makes up the second part of the document. The DTD begins with the DOCTYPE, and then details the name of the document and its structure.

The data that is actually in the second part of the document may or may not conform to the DTD. If the document does conform to the DTD the document is called a type-valid XML document, and if the document does not conform to the DTD it is called a non-type-valid XML document.

A document can be not-type-valid, and still be a good XML document.

Diff: 2 Page Ref: C-11 AACSB: Information Technology Chapter Obj.: Understand the importance of XML, including elements, XSLT, XML Schema, XPath, XQuery, and DBMS support for XML Classification: Concept 100) What is an XML Schema?

Answer: An XML schema defines the structure and content of XML documents. It is similar to a DTD specification, but better because it extends the DTD specification. Further, an XML Schema is itself an XML Schema, so no other syntax is needed. Since you can evaluate an XML document against its schema, and since XML Schemas are XML documents, you can evaluate XML Schemas. Schemas consist of elements and attributes, and elements may be simple or complex. A good rule to follow is that elements should carry data and attributes should carry metadata.

101) What is XML, and why is it significantly better than HTML? Answer: XML stands for Extensible Markup Language, and it is a subset of Standard Generalized Markup Language (SGML). XML is significantly better than HTML because: (1) XML provides a clean break between document structure, content, and materialization, which prevents the confounding of these functions; and (2) while XML is standardized, it allows for extension by application developers. The structure of any document is formally defined with XML in a standardized way.
