Object-oriented programming (OOP) developed in the early 1960s and became a dominant programming approach during the mid-1990s.Information Requirement Analysis/Soft systems methodology.Structured systems analysis and design method (SSADM) from 1980 onwards.SDM stands for System Development Methodology Cap Gemini SDM, originally from PANDATA, the first English translation was published in 1974.In some cases, a "sponsor" or "maintenance" organization distributes an official set of documents that describe the process. Methodologies, processes, and frameworks range from specific prescriptive steps that can be used directly by an organization in day-to-day work, to flexible frameworks that an organization uses to generate a custom set of steps tailored to the needs of a specific project or group. Information systems activities revolved around heavy data processing and number crunching routines". The main target of this methodology framework in the 1960s was "to develop large scale functional business systems in an age of large scale business conglomerates. The main idea of the SDLC has been "to pursue the development of information systems in a very deliberate, structured and methodical way, requiring each stage of the life cycle––from the inception of the idea to delivery of the final system––to be carried out rigidly and sequentially" within the context of the framework being applied. According to Elliott (2004), the systems development life cycle (SDLC) can be considered to be the oldest formalized methodology framework for building information systems. The software development methodology (also known as SDM) framework didn't emerge until the 1960s. The field is often considered a subset of the systems development life cycle. For example, there are many specific software development processes that fit the spiral life-cycle model. Other methodologies include waterfall, prototyping, iterative and incremental development, spiral development, rapid application development, and extreme programming.Ī life-cycle "model" is sometimes considered a more general term for a category of methodologies and a software development "process" a more specific term to refer to a specific process chosen by a specific organization. Most modern development processes can be vaguely described as agile. The methodology may include the pre-definition of specific deliverables and artifacts that are created and completed by a project team to develop or maintain an application. It is also known as a software development life cycle ( SDLC).
In software engineering, a software development process is a process of dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design, product management.
