All About Software Engineering And Development
Software engineering,​ known as​ SE,​ is​ the​ development,​ design,​ maintenance and documentation of​ software by applying practices and various technologies from fields such as​ computer science,​ engineering,​ application domains,​ project management,​ digital asset management and interface design.
The conception,​ development and verification of​ a​ software system is​ what software engineering is​ all about .​
It is​ necessary to​ identify,​ define,​ realize and verify the​ resultant software’s required characteristics .​
Necessary testing is​ required for attributes such as​ reliability,​ functionality,​ testability,​ maintainability,​ ease of​ use,​ availability and portability .​
In software engineering,​ software can be verified to​ meet these requirements by having design and technical specifications prepared and implemented correctly .​
The characteristics of​ the​ software development process are also important in​ software engineering .​
Development itself,​ development duration and risks in​ software development are examples of​ such characteristics.
A computer uses software as​ part of​ its system that allows the​ hardware to​ operate properly .​
Software can be system software or​ application software .​
System software includes the​ main operating system and a​ variety of​ other utilities that enable the​ computer and its applications to​ run .​
Application software includes the​ computer programs and relevant documentation responsible for end-user data processing tasks .​
This kind of​ software is​ developed for such tasks as​ word processing,​ payroll,​ inventory and production control.
Software Development
A series of​ processes undertaken systematically to​ improve a​ business through using computerized information systems is​ what is​ known as​ software development .​
There are two major components to​ software development,​ which are systems analysis and design.
Systems analysis is​ the​ specification of​ what exactly the​ system is​ required to​ do,​ or​ the​ main objective .​
Design is​ about how to​ make the​ system do what is​ required of​ it .​
For system analysis,​ it​ is​ required to​ study the​ current system by certain procedures in​ order to​ gather and interpret data and facts,​ identify any problems and use this data to​ improve the​ system currently in​ use .​
System design refers to​ the​ process of​ developing a​ new system,​ concentrating heavily on​ the​ technical specifications and other specifications that make the​ system operations.
Software Development Life Cycle
Software Development Life Cycle,​ or​ SDLC,​ is​ a​ sequence of​ events done by designers,​ analysts and users to​ develop and execute an​ information system .​
There are a​ number of​ stages to​ this practice,​ which can overlap .​
The stages are Preliminary investigation (which is​ feasibility study),​ Determination of​ system requirements (which is​ analysis),​ Design of​ system,​ Development of​ software,​ System testing,​ System Implementation and System Maintenance in​ that order.
