With all the complex processes involved in software development, it's easy to forget the fundamental process for a successful software development life cycle (SDLC). The SDLC process includes planning, designing, developing, testing and deploying with ongoing maintenance to create and manage applications efficiently.

What is software developing life cycle?

SDLC or the Software Development Life Cycle is a process that produces software with the highest quality and lowest cost in the shortest time possible. SDLC provides a well-structured flow of phases that help an organization to quickly produce high-quality software which is well-tested and ready for production use.

    Software Testing Life Cycle (STLC) is a sequence of different activities performed during the software testing process.

    Difference between SDLC and STLC:

    It helps in developing good quality software. It helps in making the software defects free.
    SDLC phases are completed before the STLC phases. STLC phases are performed after SDLC phases.

    Detailed Solution. Capability Maturity Model (CMM) specifies an increasing series of levels of a software development organization. The higher the level, the better the software development process, hence reaching each level is an expensive and time-consuming process. Unlike other models, it is not a life cycle model.

    What is difference between agile and waterfall?

    Agile and waterfall are two distinctive methodologies of processes to complete projects or work items. Agile is an iterative methodology that incorporates a cyclic and collaborative process. Waterfall is a sequential methodology that can also be collaborative, but tasks are generally handled in a more linear process.

    What is difference between verification and validation?

    Validation is the process of checking whether the specification captures the customer's requirements, while verification is the process of checking that the software meets specifications. Verification includes all the activities associated with the producing high quality software.

    What is V model in software testing?

    The V-Model is a model used to describe testing activities as part of the software development process. The V-Model can be interpreted as an extension of the Waterfall development model, which describes the testing activities as one of the last steps in a sequential development process.

    Which is the longest phase in software life cycle?

    3) Implementation / Coding: On receiving system design documents, the work is divided in modules/units and actual coding is started. Since, in this phase the code is produced so it is the main focus for the developer. This is the longest phase of the software development life cycle.

    What is coupling and cohesion?

    " Coupling " describes the relationships between modules, and " cohesion " describes the relationships within them. This means that in a good design, the elements within a module (or class) should have internal cohesion.

    What is difference between coupling and cohesion?

    The major difference between cohesion and coupling is that cohesion deals with the interconnection between the elements of the same module. But, coupling deals with the interdependence between software modules. Cohesion is defined as the degree of relationship between elements of the same module.
