MIS561 Lab 3 Users Privileges and Roles – DeVry University MySQL, like many other databases, uses the combination of specific user definitions, privileges, and roles to control access to the data in the database.

Very important!

Be sure to save all screenshots on Terminal and MySQL Workbench while executing your SQL code when working on the lab.

Deliverables Grading of the lab assignment will be based on the following.

Part 1: Using Command Line on Terminal a) Add two new users. Grant super user access to one and read-only access to all tables in the database to the second user (Step 1, Step 2, and Step 3).

To prove the super-user access for User 1, please write query to SELECT, DELETE, INSERT, UPDATE from any created table and show successful results.

To prove the read-only access for User 2, please write query to SELECT, DELETE, INSERT, UPDATE from any created table. SELECT, DELETE, INSERT, UPDATE from any created table (Note: Only SELECT query will be eligible.)

Sample of commands to check access: Mysql>show databases; – will list database names; Mysql>use database name; – Access allowed or denied.

Add screenshots to Report. b) Modify access of the second user by adding update access to Employee table (Step 4). Add screenshots to Report.

To prove the UPDATE privilege, please log in again as User 2 and update COMM column in Employee table.

MYSQL> UPDATE Employee SET COMM = 0.1; Add screenshots to Report.

Note!

This is a difficult assignment to grade, so please combine multiple outputs in a single document in the order of execution. Addition of headings for each step helps clarity. Also, please trim out any errors and unnecessary content. iLAB STEPS Part 1: Using command line on Terminal STEP 1: Creating a new user using command line on Terminal To start, launch Start, choose MySQL 5.6 Command Line Client – Unicode Enter password: Enter your password, which you’ve created during installation; Press Enter; We’ll check the existing users by: Mysql> select Host, User from mysql.user; Your response will look like this: HOST USER —————— ———————– 127.0.0.1 root Localhost student1 Now, to add new user: Mysql> CREATE USER ‘username’@’localhost’ IDENTIFIED BY ‘password’; Press Enter.

Please note: Username and password are in a single quotes. Statement is ended with semicolon.

Please add before and after screenshots to the Report.

STEP 2: Finding information on users To verify currently defined users, write and execute the query to display the following information: Mysql> select Host, User from mysql.user; And the result set will include a newly created user.

HOST USER —————— ————— 127.0.0.1 root Localhost student1 Localhost student2 Please add Before and After screenshots to the Report.

STEP 3: Finding User Privileges Creating a user doesn’t give any access to databases.

We have to grant the privileges to the user.

For example, command below grants ‘super user’ privileges: Mysql> GRANT ALL on *.* TO ‘user name’@‘localhost’ WITH GRANT OPTION; Press Enter.

Where ALL – all privileges; *.* – to all databases, all tables; Mysql>flush privileges; Press Enter.

Mysql>quit To remove user: Mysql>DROP USER ‘user name’@’localhost’; Press Enter.

To show all users and their privileges: Mysql>select * from mysqluser; Press Enter.

To show privileges: Mysql>show grants for ‘username’@’localhost’; The result set will include grants for user and encrypted password.

Please add Before and After screenshots to the Report.

STEP 4: Changing User Specifications Command below grants user with UPDATE privilege to Employee table: Mysql> GRANT UPDATE on *.Employee TO ‘user name’@‘localhost’ WITH GRANT OPTION; Press Enter.

Where *.Employee – to all databases, Employee table; Mysql>flush privileges; Press Enter.

Mysql>quit To show grants, log in again and type command: Mysql>show grants for ‘username’@’localhost’;

The result set will include grants for user and encrypted password.

Please add Before and After screenshots to the Report.

Part 2: Using MySQL Workbench a) Add two new users. Grant ‘super user’ access to one and read-only access to all tables in the database to the second user (Step 1, Step 2, and Step 3).

To prove the super user access for User 1, please write query to SELECT, DELETE, INSERT, UPDATE from any created table and show successful results.

To prove the read-only access for User 2, please write query to SELECT, DELETE, INSERT, UPDATE from any created table. (Note: Only SELECT query will be eligible. DELETE, INSERT, UPDATE will result in an access denied message.)

Add screenshots to Report. b) Modify access of the second user by adding update access to Employee table (Step 4).

Add screenshots to Report.

To prove the UPDATE privilege, please log in again as User 2 and update COMM column in Employee table.

MYSQL> UPDATE Employee SET COMM = 0.1; STEP 1: Creating a new user using MySQL Workbench To start, launch Start, choose MySQL Workbench, Press Enter.

Choose your schema on Home page to connect to MySQL Server.

Enter password; Press OK. On the left part of the screen, under the Schema, choose your database schema.

Under the Management, click User and Privileges, Enter password to connect to MYSQL Server.

Screen Administration: User and Privileges allows you to add a new user.

Click Add Account button and fill required information in Login screen.

Repeat for the second user.

Please add screenshots to the Report.

STEP 2: Finding information on users.

STEP 3: Finding user privileges.

STEP 4: Listing privileges associated with a role.

Complete Account Limits, Administrative Roles, and Schema Privileges tabs for User 1 and User 2.

Please add screenshots to the Report.

STEP 5: Changing user specifications. Assigning users to a role.

Add UPDATE privilege on Administrative Roles tab for User 2.

Please add screenshots to the Report.

STEP 6: Verifying role content.

Click on Create a new SQL tab for executing query (located on the left corner below the File tab) to start new Query page.

Please prove super user privilege for user 1 by writing and executing SELECT, INSERT,

DELETE, UPDATE statements.

To prove the UPDATE privilege for User 2, log in again as User 2 and update COMM column in Employee table.

UPDATE Employee SET COMM = 0.1; Please add screenshots to the Report.

This concludes the Lab for Week 3.

According to the test, every person has one dominant trait in each category. The theory is that every person will fall into one of the 16 personality types.

This test can be used as a guide to help pinpoint personality traits, possible career paths, and provide some explanation for why and how we pick our friends, romantic partners and how we interact with the outside world as a whole.

The other test that is used is The Big 5, this test has 5 main categories, where as the MyersBriggs has only 4.

This test is shorter and less invasive than the Myers-Briggs, and has the acronym that gives a percentage of that letter found from the results of the few questions answered. “OCEAN” standing for Open-Mindedness, conscientious, extraversion, agreeableness and negative emotionality.
