Concurrent models are those models within which the various activities of software development happen at the same time, for faster development and a better outcome. The concurrent model is also referred to as a parallel working model. The waterfall model provides a picture of phases working linearly and sequentially. Advantages: The concurrent process model is applicable to all types of software development and provides an accurate picture of the current state of a project. Agile Development Using Code Branches The Agile software development methodology enables rapid and flexible response to change. Agile often involves concurrent development and requires that the application code base (trunk) always exists in a buildable state. To facilitate agile development, users make code changes in code branches. Concurrent Development ProcessWith CA EndevorĀ® SCM, code branches are implemented using sandbox Subsystems (sandboxes). Each sandbox serves as a branch, that is, a separate development work area that maps to the trunk. This development method is referred to as the CA Endevor SCM sandbox development method for concurrent development. Meaning Of Development ProcessAfter the user creates a sandbox for a project, they copy the Elements that require changes into that sandbox. When the Elements get generated, the generate processor automatically uses (concatenates) the unchanged current source code from the trunk. The generate processor creates an executable form of the Element, together with any associated outputs (such as listings). This process keeps the application trunk stable. Key code windows xp. In the following graphic, three branches (development sandboxes) map to an application trunk to support concurrent development.
