Software is a collection of computer data and instructions organized in a specific order.Software is generally divided into system software、Application software and middleware software between them.Software doesn't just include programs that can run on a computer,Documentation related to these programs、Elements such as data are generally considered part of the software.

With the rapid development and wide application of computer technology,Software from the original computer hardware accessories,Just as the operation of computer hardware and some simple calculation and data processing programs,Today's large-scale closed or open system software and application software.Software is abstract,It is the product of human logical thinking,It is not restricted by material,It is not restricted by the laws of physics or the processing process,This feature simplifies software engineering,Because the potential of software is not limited by physical factors;On the other hand,Due to the lack of natural constraints,Due to the lack of natural constraint software system in the implementation process,Easily become extremely complex,It's hard to understand、It's more expensive to change it.Software scale growth,So that the complexity is greatly increased,The incompatibility between high complexity and high reliability,Make software reliability decrease with the increase of its scale,Quality is hard to guarantee,More difficult to maintain,It's hard to control the investment budget,Traditional software development methods can not meet the needs of large-scale software development.
