@. SDLC:
The full meaning of SDLC is Software Development Life Cycle.
SDLC is a process used by the software industry to design, develop and test high quality software.
SDLC is a process followed for a software project, within a software organization.
The typical stages in the Software Development Life Cycle include:
- Requirements Gathering:
In this phase, project stakeholders, including clients, users, and developers, gather and document the software requirements. This involves understanding the needs, goals, and functionalities expected from the software.
- Analysis and Planning or Define Requirements:
During this stage, the development team analyzes the gathered requirements, assesses the project scope, defines a plan, and estimates the resources and time required for the project.
- Design:
In the design phase, the system architecture and software design are created based on the requirements. It includes defining the software’s structure, data models, algorithms, and user interface design.
- Implementation or Develop or Coding:
In this phase, the actual coding and programming of the software are carried out. Developers write the source code based on the design specifications.
- Testing:
The software is thoroughly tested to identify and fix any defects or issues. Different testing methods, such as unit testing, integration testing, system testing, and user acceptance testing, are employed to ensure the software meets the specified requirements.
- Deployment:
Once the testing phase is successful, the software is deployed to the production environment or made available to end-users.
- Maintenance:
After deployment, the software enters the maintenance phase, where updates, bug fixes, and improvements are made to ensure its continued functionality and usability.
The SDLC is a cyclical process, and iterations may be required to improve and enhance the software over time.
Different methodologies and approaches, such as Waterfall, Agile, and DevOps, are used to implement the Software Development Life Cycle, depending on the project’s requirements and complexity.
Each phase in the SDLC has its specific goals and deliverables, and effective management and communication are essential throughout the development process to ensure successful software development and delivery.
