Print Outline
Course Description:
This subject continues the study of database design and SQL begun in DBS201. Students will learn the entire set of SQL statements using Oracle's DBMS. Students will also learn Oracle's SQL *Plus commands. Students will work in teams to prepare and implement the logical and physical database schema for a business application requiring 12-18 tables including all necessary contraints to protect the integrity of the data.
Credit Status: 1 credit (3 units)
Required for CPA - Computer Programming and Analysis (Ontario College Advanced Diploma)
Required for CPD - Computer Programmer (Ontario College Diploma)
Prerequisite: DBS201
Mode of Instruction: 3 hours interactive lecture per week.
1 hour lab time per week.
Learning Outcomes:
1. Identify all constraints required to maintain data integrity for a business application

2. Work effectively as a member of a team to analyse data requirements, prepare an Entity Relationship Diagram, normalize application user views and prepare a logical database schema for a business application requiring more than 12 tables

3. Identify use of necessary indexes, views and sequences for an application

4. Implement, maintain and retrieve data using an Oracle database for a complex business application

5. Use SQL's Data Definition Language statements of CREATE, ALTER and DROP to create, modify and drop database objects including tables, views, sequences and indexes with all constraints required to maintain data and referential integrity

6. Use SQL*Plus commands to efficiently create, edit and run SQL statements and to format SQL output

7. Use SQL's Data Manipulation Language statements of INSERT, UPDATE and DELETE to add, change and delete application data from tables

8. Use SQL's Transaction Control Language statements of COMMIT to make database changes permanent and ROLLBACK to undo database changes

9. Use SQL's Data Control Language statements of GRANT and REVOKE to permit and remove access to database objects

10. Use commands from SQL*Plus, Oracle's extension to the SQL language, to customize a session environment

11. Use iSQL*Plus to create and run SQL statements

12. Use SQL's SELECT statement to retrieve data required by an application, including use of single row and group functions, nested queries and correlated sub-queries
