Types of Software Systems.

A software system is a system based on software forming part of a computer system (a combination of hardware and software). The term software system is often used as a synonym of computer programs me or software the term software system is related to the application of systems theory approaches in software engineering context. This approach is often used to study large and complex software, because it focuses on the major components of software and their interactions. The term software system is also related to the field of software architecture.

Major categories of software systems include application software, programming software and system software, although the distinction can sometimes be difficult. Examples of software systems include computer reservations system, air traffic control software, military command and control systems, telecommunication networks, web browsers, content management systems, database management systems, expert systems, spreadsheets, theorem plovers, window systems, word processors, etc. Software systems are an active area of research for groups interested in software engineering in particular and systems engineering in general.

Practical computer systems divide software systems into three major classes: system software, programming software and application software, although the distinction is arbitrary, and often blurred.

System software

System software helps run the computer hardware and computer system, it includes:

• Text editors’ compilers

• Interpreters

• Linkers

• Debuggers, and so on

An Integrated development environment (IDE) merges those tools into a software bundle, and a programmer may not need to type multiple commands for compiling, interpreting, debugging, tracing, and etc., because the IDE usually has an advanced graphic user interface or GUI.

Programming software

Programming software provides tools to assist a programming in writing，computer programs and software using different programming languages in a more convenient way. The tools include:

• Text editors

• Compilers

• Interpreters

• Debuggers, and so on

An integrated development environment (IDE)merges those tools into a software bundle, and a programmer may not need to type multiple commands for compiling, interpreting, debugging, tracing, and etc,, because the IDE usually has an advanced graphic user interface, or GUI.

Application software

Application software allows end users to accomplish one or more specific (non-computer related) tasks typical applications include:

• Industrial automaton

•business software

• Educational software

• Medical software

• Databases

• Computer games
