With the technology shaping the modern world the need to build applications to run your technology gadgets is increasing day by day. Perhaps that the reason that the Information technology sector and the job opportunities this sector has to offer is selling like hot cakes. One of the major disciplines directly related to information technology is called software engineering. If we have to define software engineering it is said to be creation, designing, testing, developing and running full fledge functional programs, soft ware and applications. The person who makes and develops the applications is commonly known as software engineer.
The software engineering performs in a controlled environment and is amalgam of science, technology, principles of engineering and computer to structure, practice and conserve the software systems. The basic reason or purpose behind the development of soft wares or applications is to maintain high quality standards, provide ease and convenience to users in standardized procedures and entertainment purposes.
Most of the time spent while designing software is the software development life cycle that involves seventy percent documentation of the work with the help of technical writers including algorithms, codes and user manuals explaining how to run the specific application while thirty percent of the remaining work is of coding and documentation. The software development is the costly procedure as it involves a lot of writing and it takes a lot of money and effort to document the procedures.
The product that comes out as result of software engineering is most of the time took a great deal of time while shifting its shape from plan to actual realization. Every stage is carefully planned and includes the time of planning and building the model separately. The stages are sometimes dependent and sometimes independent of each other but most of the time the product we get out of one stage is utilized in other stage to process further. Every stage has mile stones to achieve and deliverables to deliver on time. If a single deliverable is delayed it results in delay of whole project and ultimately results in increased cost of the project which can lead to project failure so such circumstances are highly avoidable.
Usually the software engineering procedure can follow one of three approaches or a hybrid of three. To name the three approaches are water fall model it is said o be the oldest one is mostly deployed to design the army related applications. A great example of the soft ware engineering is the procurement function of the military.
Once the software is designed is repeatedly modified, upgraded, maintained, protected and customized according to the needs of the customer to suit his or her set of objectives, purposes and business model.
More and more companies are shifting from solid model to the world of Internet by following online model which has cause an increase in demand of soft ware application development that has resulted in huge stress on the soft ware industry for the quality and quick development that offer efficiency without flaw.
