SDLC - A Short Introduction

SDLC (System Development Life Cycle) is a complete process of designing or redesigning a software system in the best possible manner. It takes into account various factors right from the starting point and is completely goal oriented with proper time frame, in depth analysis and hassle free advancement of the entire project. For the system to be built, analyzing the project viability, examining setbacks, selecting design and architecture of the system, enforcing and trying it, up-till the handing over the system is the complete responsibility of the sdlc life cycle.

Software Development Life Cycle is a procedure of steady fine-tuning, denoting that it is carried out through quite a lot of development stages. Each stage continues and fine-tunes what was achieved in the preceding phase. All these activities are generally known as development phases in the SDLC. The following are different stages:

Planning

Planning is the process of realizing the reasons behind the building of the system and determining its necessities. It in addition includes possibility study from quite a lot of diverse viewpoints, practical, financial, and organizational viability features.

Analysis and Designing

Analysis is the stage which includes activities for instance identifying and analyzing the problems, and even forecasting possible troubles that may take place in the future with regard to the system. The products of this segment will drive the ways and means of building the system in addition to guiding the programmers’ works.

System analysis contributes to design judgment, which precisely determines the way the system will operate in relation to process, information, peripheral devices, network substructures, graphical user interface, along with other critical indicators within the system environment.

Implementation

Implementation is essentially the most source-, price-, and time-taking stage of all. This is where the system is in fact built, tested, and ultimately installed. Furthermore, it includes activities for instance training the user as well as system upholding. Some professionals prefer to split them into diverse phases like preparation and preservation. Nevertheless the 4 phases are classified as the most general and established steps.

Deployment and Maintenance

When the software program is carried out, it doesn't imply that the software program is a useful one as it is. All SDLC examples consist of maintenance because there are virtually no methods in which the software will probably be working flawlessly. Someone needs to remain in the current software to look and be sure this software works faultlessly when it is enforced in public. Maintenance is by all means an easy task provided that the right product is served within an anticipated time frame.

SDLC methodologies are way too complex and needs long term understanding. This is a simple excerpt on the vast topic about software development.
