Definition - What does Software Development Life Cycle (SDLC) mean? The software development life cycle (SDLC) is a framework defining tasks performed at each step in the software development process. SDLC is a structure followed by a development team within the software organization. It consists of a detailed plan describing how to develop‚ maintain and replace specific software. The life cycle defines a methodology for improving the quality of software and the overall development process.

creates a tree-like structure called the syntax tree. * The syntax analyzer checks whether the order of tokens conform to the rules of the programming language. Unmatched parenthesis‚ missing semicolons are some of the errors detected in this phase. * If there are no errors in the code‚ the syntax analyser successfully constructs a syntax tree which is later used by the semantic analyser. Semantic Analysis: * “Semantic” by definition is concerned with meanings. A semantic analyser

security into the SDLC A key component of the software development life cycle is verifying that application is secure. Tests of an application’s security can happen in any phase of the SDLC. However‚ in the alpha and beta phases‚ there should be constant security testing. Key areas that must be considered as part of overall security vulnerability testing include the application’s design‚ default security measures‚ mass deployment security‚ and information and response abilities.

Development Life Cycle (SDLC) process applies to information system development projects ensuring that all functional and user requirements and agency strategic goals and objectives are met. The SDLC provides a structured and standardized process for all phases of any system development effort. These phases track the development of a system through several development stages from feasibility analysis‚ system planning and concept development; to acquisition and requirements definition; design; development;
