In software engineering, after the planning stage of an application or system, called requirements modeling, the architectural design of the software follows. Component-based software engineering: technologies, development frameworks, and quality assurance schemes Abstract: Component-based software development approach is based on the idea to develop software systems by selecting appropriate off-the-shelf components and then to assemble them with a well-defined software architecture. Components are used to describe specific software services, and ports are used to connect components together[8-10]. All rights reserved. The advantages and disadvantages of component-based software development (CSBD) are discussed. A component-based process model: The creation of software is characterized by change and instability and therefore any diagrammatic representation of the component-based process model should consider overlapping and iteration between its phases. Five Models It is another approach to communicate with system. In the conventional view of component-level design, the component is considered a functional element of the software that integrates the processing logic and necessary internal data structures to perform its task, as well as the interface that allows for calling the component and passing data to it. The shortcut should be easily remembered by the users. The following process stages can take place in this software development model. To achieve object-oriented design it elaborates analysis classes and the infrastructure classes.
