What Do You Mean By Software Design Life Cycle?

Software Design Life Cycle (SDLC) refers to a set of actions that is must for designing software application and this set leads from the beginning to the final stage of software. For example; feasibility study is the beginning stage of software design life Software Design Life Cycle (SDLC) and deals with the analysis for an application to ensure that the required software application is either feasible to develop or not feasible to design. Actually feasibility deals with the resources and requirements. If it can be discover that the software is feasible the development team goes to the next steps. Basically requirement analysis, design, implementation, testing and maintenance are the basic steps of Software Design Life Cycle (SDLC).

I have already introduced feasibility study, feasibility study is also known as the requirement analysis. Design step is the next step of Software Design Life Cycle (SDLC). In this step is for software architect and this type of top level person decide and design software application with different modules and their relationships. Database design is also a part of software design. Implementation comes after the design step. Languages selection and coding are the main task of implementation. Software developers code the software as designed by the architect and forward to the SQA for test the software.

Testing step is one of the most important steps in Software Design Life Cycle (SDLC). Almost 30 % of software design effort needs to apply in this step. And finally maintenance is the most important step of Software Design Life Cycle and needs more than 50% design efforts in this phrase of software development. Because we cannot make something errorless and our design will must contain error. These errors will be resolved in the maintenance phrase of software design life cycle (SDLC).
