SDLC | Software Development Life Cycle

Meaning of SDLC

SDLC stands for Software Development Life Cycle, and it is also called the System Development Life Cycle. It explains every stage of the development of a software or system.

Database design is an important part of the SDLC. All the stages involved in creating any system are collectively called the SDLC.

Phases of SDLC in Hindi (Phases of SDLC)

The SDLC mainly consists of five phases, which are as follows:

1. Planning
2. Analysis
3. Detailed System Design
4. Implementation
5. Maintenance

1. Planning

In this phase, it is decided what the purpose of the software is and what goals it will achieve. This includes quality requirements and risk identification.

The current system is analyzed to see if it is working correctly or not. Cost estimation and planning for potential changes are also part of this phase.

2. Analysis

In this phase, the problems identified during the planning phase are analyzed in depth. The users' requirements are understood, and the hardware and software of the system are thoroughly examined.

Designers and users work together to solve the problems.

3. Detailed System Design

In this phase, a detailed blueprint of the system design is prepared. This includes technical specifications so that the system can be made more interactive and efficient.

4. Implementation

In this phase, the hardware, software, and database design are implemented. Before this, the process of coding, testing, and debugging is completed. This is the longest phase of the SDLC.

5. Maintenance

This is the final phase of the SDLC. When the system is ready and in use, the problems reported by the users are resolved.

There are three types of maintenance:

• Corrective Maintenance
• Adaptive Maintenance
• Perfective Maintenance
