STEP 1: Create Data Dictionary for provided elements

As the DBA for your company, you have decided to install a new version of the MySQL database to replace the current database version being used. The old database has become a constant headache and seems to be causing an overload on the disk drive's I/O channels. Further analysis has also shown that two primary large tables are the main points of access. The new tables will be DEPT, EMPLOYEE, and BONUS.

Describe how you plan to compile the Data Dictionary and decide on the tables structure with the new MySQLdatabase.

Given list of elements:

NN	Attribute Name	Column name	Data Type
1	Employee number (PK)	EMPNO	NUMBER(4)
2	Employee first name	EFNAME	VARCHAR2(10)
3	Employee last name	ELNAME	VARCHAR2(20)
4	Job category (FK)	JOBCATEGORY	VARCHAR2(4)
5	Manager	MGR	NUMBER (4)
6	Hire date	HIREDATE	DATE
7	Salary	SAL	NUMBER (7.2)
8	Commission	COMM	NUMBER (7.2)
9	Department number(FK)	DEPTNO	NUMBER(2)
10	Department name	DEPTNAME	VARCHAR2(14)
11	Location	LOC	VARCHAR2(13)
12	Job title	JOBTITLE	VARCHAR2(20)
13	Job description	JOBDESC	VARCHAR2(20)

Compile Data Dictionary (in alphabetic order):

NN	Attribute Name	Column name	Data Type	Data element description	Table name	Primary key/ Foreign key indicator (P/F)	Not NULL	Default value
	Department number	DEPTNO	NUMBER(2)

Place and save your answers in a Word document named "yourname_Lab_2.docx."

STEP 2: Create SCHEMA and database tables in MySQL Workbench

2.a Create SCHEMA

Launch MySQL Workbench;

Click File and choose New Model;

Add Diagram:

Name: new schema name;

Press Enter and new SCHEMA will be added;

2.b Create tables

a) In Model overview (top part of the screen) Click Add Diagram; Navigation pane shows new schema in Catalog Tree;

b) Place a new table on the free part of screen;

c) Fill:

Table Name:

Column Name, Datatype;PK; NN; UQ;BIN; UN; ZF;AI; Default;

Press Enter

For example, starting/stopping the MySQL instance or editing the configuration file Fill out the connection details and optionally click Configure Server Managementto execute the Server Management wizard. Click OK to save the connection.

Important

All connections opened by MySQL Workbench automatically set the client character set to utf8. Manually changing the client character set, such as using SET NAMES ..., may cause MySQL Workbench to not correctly display the characters.

New connections are added to the Home page as a tile, and multiple connections may be opened simultaneously in MySQL Workbench.

Part 2 Configure a New MySQL Connection

Click on Local Instance MySQLand enter password;

Local Instance MySQLscreen appears;

Click MySQL Workbench Home, click database to be connected;

EER Diagram screen appears;

Choose Database on Toolbar and Forward Engineering on scroll menu;

Forward Engineer to Database screen appears

Set parameters for Connecting to a DBMS:

Stored Connection: Select from saved connection settings; Click Next;

Set Options for Database to be Created appears

Select DROP objects before each CREATE object;

Leave selected Include model attached script; Click Next;

Select Objects to Forward Engineer screen appears, enter password again;

Select Export MySQL Table Objects and click Next;

Review the SQL script to be Executed screen appears for your review and saving to file or copy to Clipboard; Click Next;

Forward Engineering Progress screen appears, enter password again;

Forward Engineering Progress shows the executed tasks.

Click Close.

Please add Management, INSTANCE and PERFORMANCE screenshots for the created database to lab Report.

STEP 4: Insert data to tables using MySQL Workbench

Copy INSERT statements for the given tables into the notepad;

Launch to MySQL Workbench Home page;

Choose created database instance; enter password;

New screen appears with the Connection name;

Choose in Navigator your schemas name;

Copy script from Notepad to screen Query 1;

Highlight executable rows, choose Query on the Toolbar and Execute (All or Selection);

Output will display the results of the execution.
