Study Notes

Software Engineering Basics

Software is computer programs and associated documentation.
Software engineering is an engineering discipline that is concerned with all aspects of software production.

Software Characteristics

Efficiency: means that the software should not make wasteful use of system resources such as memory and processor cycles.
Acceptability: means that the software must be understandable, usable and compatible with other systems.
Maintainability: means that the software should be written in such a way so that it can evolve to meet the changing needs of customers.
Dependability: includes a range of characteristics including reliability, security, and safety.

Software Development Life Cycle

Software specification: involves defining the software that is to be produced and constraints.
Software development: involves designing and programming the software.
Software validation: involves checking the software to ensure that it is what the customer requires.
Software evolution: involves modifying the software to reflect changing customer and market requirements.

Types of Software Applications

Stand-alone applications: are application systems that run on a local computer, such as a PC.
Interactive transaction-based applications: are applications that execute on a remote computer and that are accessed by users from their own PCs or terminals.
Embedded control systems: are software control systems that control and manage hardware devices.
Batch processing systems: are business systems that process large numbers of individual inputs to create corresponding outputs.

Software Engineering Methods and Techniques

The types of software engineering methods and techniques depend on the organization developing the software, type of software, and people involved in the development process.
Software engineering is concerned with project management and the development of tools, methods, etc. to support software production.

Professional Responsibilities

Issues of professional responsibilities of software engineering include confidentiality, competence, and intellectual property rights.
