Subject Title
On-line Systems

Subject Description
This subject continues on from PRG 455 where the student had been introduced to Structured Query Language. This subject explores SQL in greater detail covering more complex queries and creating / managing database objects. Students gain conceptual insight into and hands-on experiences with a commercial distributed database system, Oracle, which will allow students to understand current institutional uses of distributed computer systems. Non-procedural SQL language skills, relational data base tools (Oracle SQL*PLUS and/or Oracle SQL Developer), small project planning and management practices, application interface design principles and effective student team work will be applied to a significant RDBMS project.

Credit Status
One subject credit in the Computer Engineering Technology program.

Learning Outcomes
Upon successful completion of this subject the student will be able to:

  1. Connect to the database and run SQL scripts using Oracle SQL*Plus or Oracle SQL Developer
  2. Create basic SELECT statements that use virtual columns, aggregates, row filtering, and sorting
  3. Create and alter tables using SQL DDL statements that incorporate column constraints, table constraints, and referential integrity constraints
  4. Design a database from scratch using Entity-Relationship modelling and database normalization
  5. Modify data in the database using the Data Manipulation Language (DML) statements INSERT, UPDATE, and DELETE
  6. Create and use sequences to generate surrogate keys
  7. Use SQL transactions to group DML statements into logical units of work
  8. Create and use advanced SELECT statements that include joins, subqueries, sets, and create and use views based on those SELECT statements
  9. Grant and Revoke privileges on database objects
  10. Write front-end application code and back-end stored procedures and functions which use the PL/SQL language and which use PL/SQL cursors
  11. Build and run multi-page GUI Event Driven client applications which communicate with the back-end Oracle server and make use of views, stored procedures, and user-defined functions within the database
