       Course Name: Introduction to Systems Analysis and Design

       Credits: 3 (3 lecture; 1 lab)

II.    Prerequisite

Recommended: CIS 101 or CIS 103 and one programming language course or concurrent enrollment in one programming language course.

III.   Course (Catalog) Description

Course introduces the systems development life cycle of a computer system. Content includes the investigation, analysis, design, implementation and evaluation phases of a business system, tools (e.g. CASE) and techniques used by the systems analyst.

IV.   Learning Objectives

Upon completion of this course, the student will be capable of applying the fundamental skills that are needed by the systems analyst for business data processing.

The student will be able to explain the role of information systems in the business environment and will be able to demonstrate competence in performing the steps involved in the development of a simple system:

  1. Preliminary investigation
  2. Detailed investigation and analysis of specific systems requirements
  3. General design of the system
  4. Detailed systems design
  5. System implementation
  6. Evaluation

V.    Academic Integrity

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct. This code prohibits:

• cheating,
• plagiarism (turning in work not written by you, or lacking proper citation),
• falsification and fabrication (lying or distorting the truth),
• helping others to cheat,
• unauthorized changes on official documents,
• pretending to be someone else or having someone else pretend to be you,
• making or accepting bribes, special favors, or threats, and
• any other behavior that violates academic integrity.

There are serious consequences to violations of the academic integrity policy. Oakton's policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.
Details of the Code of Academic Conduct can be found in the Student Handbook.
