SDLC

Testing

The code is tested at various levels in software testing. Unit, system and user acceptance testings are often performed.

SDLC?

SDLC (Software Development Life Cycle) is the process of developing software through business needs, analysis, design, implementation and maintenance

The Phases of SDLC

Investigation System Analysis Design Testing Operations and Maintenance

Design

-In systems design the design functions and operations are described in detail, including screen layouts, business rules, process diagrams and other documentation. The output of this stage will describe the new system as a collection of modules or subsystems.

Investigation

The 1st stage of SDLC is the investigation phase. During this stage, business opportunities and problems are identified, and information technology solutions are discussed.

Operations and Maintenance

The deployment of the system includes changes and enhancements before the decommissioning or sunset of the system. Maintaining the system is an important aspect of SDLC. As key personnel change positions in the organization, new changes will be implemented, which will require system.

System Analysis

The goal of system analysis is to determine where the problem is in an attempt to fix the system.This step involves breaking down the system in different pieces to analyze the situation, analyzing project goals, breaking down what needs to be created and attempting to engage users so that definite requirements can be defined.
