71) What is a stored procedure?
Answer: A stored procedure is a module of procedural logic that is written in a language provided by the DBMS and stored inside the database. The stored procedure can be invoked, passed parameters, and return results just as a typical program function. Since the stored procedure is stored in the database, it is available to application programs, ASP or JSP pages, and interactive queries.
Diff: 1 Page Ref: 395
72) What is a trigger?
Answer: A trigger is a module of procedural logic that is written in a language provided by the DBMS and stored inside the database. The trigger is invoked automatically by the DBMS whenever certain events occur.
Diff: 1 Page Ref: 396
73) Briefly describe three types of triggers.
Answer: Common types of triggers include BEFORE triggers, AFTER triggers, and INSTEAD OF triggers. BEFORE triggers are modules of procedural logic that the DBMS automatically invokes before inserting, updating, or deleting data. An AFTER trigger is a module of procedural logic that the DBMS automatically invokes after inserting, updating, or deleting data. INSTEAD OF triggers are modules of procedural logic that the DBMS automatically invokes in place of inserting, updating, or deleting data.

74) What are the common differences between a Web database processing system running on the Windows operating system and one running on a Linux operating system?
Answer: If a Web server is running the Windows operating system, the Web server software will usually be Internet Information Services (IIS) and the Web pages may use ASP pages to integrate application logic with HTML. If a Web server is running the Linux operating system, the Web server software will usually be Apache, the database will typically be MySQL, and the Web pages may use PHP and Pearl to integrate application logic with HTML. This combination is called LAMP. Note that Apache, MySQL and PHP/Pearl can run on a Windows systems, in which case the combination is referred to as WAMP.

75) What is a three-tier architecture?
Answer: The term tier refers to each different computer that runs a portion of a Web database processing environment. The user's browser running on the user's own computer is one tier, and a Web server running on another computer is another tier. If the DBMS supporting the Web application runs on yet another computer, there is a third tier, and the computer environment is referred to as a three-tier architecture.
Diff: 2 Page Ref: 397-398
76) Define and briefly describe the function of ODBC.
Answer: ODBC stands for Open Database Connectivity. It is used to solve the problem caused by each DBMS having its own proprietary application program interface (API). OBDC was created to be a bridge between program code and the APIs. A programmer can write code using ODBC standard statements, and an ODBC driver translates these statements into a form that the DBMS API can understand. Similarly, results sent though the API back to OBDC are translated into standard ODBC forms. This allows application programmers to write to OBDC as a common interface rather than having to learn many APIs.

77) Briefly describe PHP.
Answer: PHP, which is an abbreviation for PHP: Hypertext Processor, is a popular scripting language that can be embedded in Web pages. PHP allows users to connect to databases, run SQL commands against the databases, and then process the results of the SQL commands for display on Web pages. PHP commands are enclosed in <?php and ?> elements.

79) What is XML, and why is it useful?
Answer: XML stands for Extensible Markup Language. XML is a markup language like HTTP, but it allows users to define their own tags. XML is used to define the structure of documents and for transmitting documents between computers. It is important for database processing because it provides a standardized means of sending and receiving data to and from a database.
Diff: 2 Page Ref: 405, 424-426
80) How can XML be used with a DBMS?
Answer: One example is the use of XML with SQL Server. Here we use the SQL FOR XML clause to retrieve XML data from the database. The query results are returned to a single cell. This output can be expanded and copied to other documents.
Diff: 2 Page Ref: 424-425
81) What are XML Web Services?
Answer: XML Web Services is a means for sharing program elements over the Web. It involves several standards, including XML, SOAP, WSDL and UDDI. An example would be a database application that retrieves and produces weather forecasts based on ZIP codes. Using XML Web services, this application could be published so that it can be embedded in various Web pages. Users of those Web pages would then actually be using this application without realizing that it is separate from the Web page.

82) Describe how to use Microsoft Access and IIS in Web database processing applications.
Answer: When using Microsoft Access and IIS to create Web processing applications, the connection to the Access database must be provided by using an ODBC data source. The ODBC data source should be a system data source. The Web pages that access the database can use various technologies, including the popular PHP scripting language.
