Study Notes
Computer Systems Engineering
- Computer systems engineering encompasses software engineering.
- Hardware development and software development are typically integrated.
- A hardware simulator is often used during software development.
- There is a final system testing phase after integration.
Software Engineering Techniques
- The earliest computer programs were written in assembly language.
- Early programs had limited size, with just a few hundred lines of assembly code.
- Early programmers developed their own programming styles without formal processes.
- High-level programming languages like FORTRAN, ALGOL, and COBOL were introduced in the early 1960s.
- These languages significantly reduced software development efforts.
Control-flow Based Design
- Dijkstra's article "Goto Statement Considered Harmful" was published in 1969.
- The article argued for using only three programming constructs: sequence, selection, and iteration.
- This approach led to the development of structured programming methodology.
Structured Programming
- Structured programs use only sequence, selection, and iteration constructs.
- They are made up of modules, and are easier to read, understand, maintain, and develop.
- Structured programming is less prone to bugs.
Data Structure-Oriented Design
- As program sizes increased, the importance of data structure design became apparent.
- Data structure-oriented design techniques derive program structure from the design of data structures.
Life Cycle Model
- A life cycle model provides a framework for software development.
- It defines entry and exit criteria for each phase of development.
- Every phase needs to satisfy its exit criteria before moving to the next.
- Milestones help track project progress and ensure that entry and exit criteria are met.
Phases and Activities
- Testing usually consumes the most effort during software development.
- Organizations usually define standards for deliverables produced at the end of each phase.
- Each phase has defined entry and exit criteria.
- Organizations often prescribe methodologies for activities like specification, design, testing, and project management.
Feasibility Study
- The primary aim of a feasibility study is to determine if developing the software is financially worthwhile and technically feasible.
- The feasibility study typically considers the customer's requirements, including input data, processing needs, output data, and system constraints.
Cost Benefit Analysis
- CBA helps identify all costs associated with development, setup, and operation.
- Benefits are also identified and classified as quantifiable or non-quantifiable.
- The total benefits should be greater than the total costs.
