iLAB OVERVIEW
Scenario and Summary
In this lab, you will prepare a Data Dictionary based on the list
of elements. Also, your task will be determined the tables, their
relationships, primary and foreign keys. Based on this analysis,
you will create Database Schema, relational tables, Entity –
Relational Diagram (ERD), establish connection to your local
MySQL Server, create physical database and insert data to the
tables.
MySQL provides two primary types of file management:
dictionary-managed files and MySQL Workbench-managed
files. As part of this iLab, you will need to supply some
information as to how you would use both of these approaches,
and you will have to discuss some of the advantages of each.
For Step 3, you need access to your database instance. If you
have any difficulties connecting your database instance, let's
take error messages, screen shots, descriptions of the situation
to the graded threads and work as a team to resolve issues.

iLAB STEPS
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 table’s structure with the new MySQL database.
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

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)

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;

5. 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’
d) Continue to add all tables;
2.c Foreign key creation
a) Click on the bottom of the Form ‘Foreign key’ to establish
the reference to parent table;
b) Choose the Reference table and Reference column;
c) Choose Foreign key options On Update and On Delete; Enter.
2.d Save database
a) Choose ‘File’ on the Toolbar and Save Model as on your
folder.
Established database are visible on Home page.
STEP 3: Create and configure a new connection to the MySQL
Server
Part 1 Create a new connection to the MySQL Server
Launch to MySQL Workbench Home page;
To add a connection, click the [+] icon to the right of the
MySQL Connections title. This opens the Setup New
Connection form:
Figure 3.1 Setup New Connection Form
Important note:
The Setup New Connection form features a Configure Server
Management button (bottom left) that is required for the
MySQL connection to perform tasks that requires shell access to
the host. For example, starting/stopping the MySQL instance or
editing the configuration file Fill out the connection details and
optionally click Configure Server Management to execute the
Server Management wizard. Click OK to save the connection.
Important

6. 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 MySQL’ and enter password;
Local Instance MySQL screen 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;

7. Choose created database instance; enter password;
New screen appears with the Connection name;
Choose in Navigator your schema’s 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.
Please select counters and rows in database tables and add
screenshots to lab Report.
