Quick Overview

ITCO231 Unit 5 HR Database


Update the database diagram, and generate the data definition language (DDL) for the Contacts table and any others that you wish according to the following diagram. Be sure to define the appropriate relationship between the Contact table and the Employee table.


Add data to your database and validate that your records loaded properly. In tabular format, include 3 rows for each table, making sure that the primary–key and foreign–key relationships are properly applied.
Next, you will insert the 20 rows of data that you identified (using the concepts you worked on identifying the primary and foreign keys), then perform queries using JOIN syntax of the database.
Task 1: Create 3 rows of data for each table ensuring that the referential integrity is valid.
Task 2: Add the 20 rows of data to the appropriate table in your database (using any appropriate method available).
Task 3: SELECT all columns and all rows of the tables. Create a screenshot of each query and output data, and submit them.
Task 4: Write SELECT statements for the following (include a screenshot of the SQL and its execution, including the resulting data):
Display the employee id, contact id, first_name, middle name, last_name, and phone number for all employees.
Rows returned
Display the employee id, contact id, first_name, middle name and last_name, and email address for all employees.
Rows returned
Display the employee id, contact id, first_name, middle name, last_name, phone number, and email address for all employees.
Rows returned
Combine all of the DDL/SQL statements (text only), diagram and screenshots into a single Word document. Submit it for grading.
