Study Notes
Software Development Life Cycle (SDLC)
- The SDLC is a methodical process divided into seven phases, each crucial for successful software development.
- The SDLC is adaptable, allowing for adjustments and streamlining the process.
- The SDLC aims to reduce development costs, improve software quality, and minimize development time.
Phases of SDLC
- Planning: This phase involves gathering, analyzing, and prioritizing information to create a development plan. This phase also includes feasibility studies to assess the viability of the project.
- Analysis: During this phase, analysts determine and document detailed system requirements using tools like Class Diagrams, Use Cases, and Activity Diagrams. These diagrams visualize business functions and their processes.
- Design: This phase involves creating a logical design for the system based on collected requirements. This includes designing the user interface, files, and databases.
- High-Level Design (HLD): Includes high-level components, outlines of module functionality, dependency relationships, database structures, and architecture diagrams.
- Low-Level Design (LLD): Focuses on the detailed functional logic of modules, specific database structures, interface details, dependency issues, error messages, and input/output specifications for each module.
- Implementation: In this phase, developers write code using the chosen programming language. Code is often divided into units or modules and assigned to different developers. This is the longest phase of the SDLC. Developers need to follow coding guidelines and utilize programming tools like compilers, interpreters, and debuggers.
- Testing: Thorough system testing is vital to identify and fix problems before deployment. Programmers and system analysts conduct testing using both sample and actual data from the current system.
- Deployment & Maintenance: This is the final phase where the software is deployed, users are trained on the new system, and continual maintenance and updates are carried out.
The Waterfall Model
- The Waterfall model is a traditional SDLC model that follows a linear, sequential approach.
- Each phase is completed before moving to the next.
- There is less flexibility for changes after a phase is completed.
