Some computer system frameworks also include actual programs, specify programming interfaces, or offer programming tools for using the frameworks.
What are the phases of the framework?Framework is the process of getting through the initiation, requirements collection, design, implementation, testing and deployment stages of a project to produce an application or service.
What are the stages of developing an information system?An information system development consists of six important stages, it is system survey, needs analysis, design, implementation, testing, change and maintenance.
What are the concepts frameworks and components of information systems?An information system is essentially made up of five components hardware, software, database, network and people. These five components integrate to perform input, process, output, feedback and control. Hardware consists of input/output device, processor, operating system and media devices.
