What is SDLC?

S - Software (System)

D- Development

L - Life

C – Cycle

It is the process to develop the software.

Steps of SDLC

• Scope Identification: Business Analyst/Project Manager

• Planning: Project Manager

• Analysis: Business Analyst

• Design: Designers/Architect

• Development: Developer

• Testing / Debugging: Software Testers

• Deployment / Installation: Developers/Deployment Engineers

• User Training and User Acceptance: Business Analyst/Project Managers

The systems development life cycle (SDLC) is a model which is used in project management that describes the different phases which involved in system development project from the begging of study of possibility of project through maintenance of the accomplished application/system.

There are several SDLC methodologies have been established in the market to monitor the processes. Some are The Waterfall model which was the original SDLC method; The Agile method; The RAD (Rapid Application Development); The V-shape model; The Fountain model; The Spiral model; The Iterative model; build and fix. Generally most of the models are collective into some sort of hybrid methodology. Irrespective of any type of the model or formula is chosen to develop new application or system, documentation is very important thig and typically documentation is done in parallel with the development of process. May be some approaches is better for particular types of project, but end of the project the most important thing is how carefully the plan was followed.

In overall, an SDLC methodology follows the subsequent steps:

  1. Evaluate the existing system. Find out inefficiencies. This.This can be done by cross-examining users of the system and denoting with personnel support.
  2. Address inefficiencies in the current system with suggestion for upgrading and address the new system requirements.
  3. Design the Project system. Laid out the plans regarding the physical structure, operating system, software design, hardware.
  4. Develop the project system. Acquired and fixed the new mechanisms and agendas. Confirmed all the aspects of new system, and if needed modification must be completed. Provide the training to users of the new system. User must be skilled in its use.
  5. System can be put on use by different way. The old system slowly phased in and replaced with new system or lock down the entire old system and implement the new system all at once.
  6. Evaluate the new system once is active and run for a while. Maintenance must be retained up carefully at all times. Users of the new system should keep themselves up to date regarding latest adjustments.

What is UML?

UML stands for Unified, Modeling, Language

UML is a visual language that let you model software and process. UML is made up of notation and diagrams.

There are four different types of UML Diagrams.

Context Diagram: Context diagram is the highest level view of a system. It is similar to block diagram. Context Diagram is very high level diagram that represents the actors outside a system that could interact with that system. Context Diagram shows system as a whole and its inputs and outputs from / to actors.

Use Case Diagram: Use Case Diagram are created to visualize the relationship between Actors and Use Cases. Use case diagram shows the relationship between the actor and the different use cases in which the actor is involved.

• Activity Diagram: Activity Diagram is used to demonstrate the sequence of activities. Activity Diagram shows the workflow from begin point to the end point with detail and the many decision point. Activity diagram are beneficial for business modeling where detail processing is involved. Very limited number of shapes are used in Activity diagram.

• Sequence Diagram: Sequence diagram is also called as Interaction diagram. Sequence diagram shows how processes function with one another and which order. A sequence diagram shows how objects interface in time series.
