por The system development life cycle (SDLC, Systems Development Life Cycle) refers to the process of planning, creating, testing, and deploying an information system.
It is important that the metadata derived from the system development life cycle and that is part of the metadata function process is defined.
In the management of development projects software It is of utmost importance to understand how the system development life cycle works because this can avoid short- and long-term errors within a project team.
System development life cycle: stages
There are different development phases involved in the system development life cycle. However, prior to these phases, there is a process called requirements gathering, that belongs to the engineering software. It is responsible for applying techniques used in other areas of engineering to develop high-quality products. software that meet the client’s requirements, are within budget and have the estimated duration regardless of their complexity.
There are two types of requirements for the life cycle of a system.
Functional: As their name indicates, they correspond to the requirements necessary to make the system work, that is, for the life cycle of a system. For example, that the system allows users to register, that it allows log inwhich allows access to a list of clients…
Non-functional: are those that are not directly related to the functionality of the system, but rather They will be important for the system to perform well in its environment. For example, the system must use the Mozilla Firefox browser version n or more.
After the definition and analysis of requirements, 4 phases of the system development life cycle are presented, these phases of the SDLC are:
Planning phase
At this stage of a system’s life cycle, a plan for the project is specified that will guide all stakeholders or stakeholders to obtain the product specified in the requirements survey.
The stakeholders correspond to the interested parties or participants of the project, that is, all the people involved in a development project software.
Design phase
In this phase of the systems life cycle, analysts or engineers software create an abstract model of the system to be built based on the functional and non-functional requirements raised in the requirements specification. This model provides details on the architecture of the softwaredata structures, interfaces and components that are needed to implement the system.
In this phase, several activities can be carried out, such as:
Architecture design. Abstract system specification. Interface design. Component design. Design of data structures. Algorithm design.
Development phase
In this phase of the life cycle of a system, the source code is generated in the chosen programming language. Here you can also define the parameterization of the software.
For code development, tools called IDEs (Integrated Development Environment) or integrated development environments, which make coding easier and more practical.
In this phase, unit tests can also be carried out that will define the versatility of the system and its failure detection capacity.
Implementation phase
In this phase of the systems life cycle, the product launch software.
Before the product is shown to the client, several tests are carried out, including:
Component testing. Systems testing (integration testing). Acceptance test.
After implementing the system in the business, it must be understood that there is a possibility of failures and, therefore, a testing, support and maintenance plan must be implemented.
