Component design assignment - Essay Exampleh acquits components proposes the possibility of making packet applications by examining together packet components in similar manner to how electronic devices are made from electronic components. This kind of method used to software growing is referred to as component based development. Component based development demands to give a thoroughly new approach to the design, construction, putting into effect and development of software applications. Software applications are bring together from components from the different kinds of sources and these components maybe written in several different programming languages and run on different methods. The desire of this trend is to reuse components that is already completed instead of developing everything from the beginning each time. There are many advantages the component-based development brings such as gives support to the higher level of software reuse, it allows testing to be done by firs t performing a test to each of the components before performing a test to the group of components, free to improve and/or add components asComponents express themselves through interfaces. An interface is the connection to the user that will interact with the component. The act upon Application Programmable Interface (API) are the once who are exposed to the user. If there are any changes to the API, the user has to recompile his code also. In the case of the object-oriented world, the interface is a group of public methods defined for an object wherein this object is controlled through its interface. In the language of C++, the code can only be recompiled when the interface (code) is changed. The task is that the user of the class must use the same programming throughout the entire development. In separating the interface from the implementation, the languages used are the COBRA and COM which is done through double star interfaces.There are three major component models that are s uccessfully used today which show accurately
