COURSE CODE

Total credit time: 90 hours

Prerequisites: EDP111, EDP318

PHILOSOPHY IGOALS:

This course provides the student with an opportunity todevelop practical data processing skills through structuredprogramming. This course also provides an opportunity forthe student to develop skills in using standard techniquesfor problem analysis through to final program testing.Emphasis is placed upon structured design, top-downdevelopments, program constructs, pseudocode, structurecharts, etc. These tools are applied to case studies.

II STUDENT PERFORMANCE OBJECTIVES:

Upon successful completion of this course, the student willbe able to:

1. identify the origin, purpose and basic structure of aprogramming language

2. design structured programs

3. write high-level programs

4. maintain files

5. use advanced features including interactive processing

6. utilize COpy and CALL
