Software reuse;  object-oriented;  Framework;  components;  Design pattern

The basic concepts and significance of software reuse are introduced, the characteristics of the framework and its connection with commonly used object-oriented reuse techniques (BFD) such as class libraries, components, and design patterns are analyzed, and the development process of framework-based software development methods is given. First, domain analysis is carried out, that is, in a given domain, through analysis to find out the common classes and objects for all applications, and establish a domain model; Secondly, combined with the domain analysis, the system requirements specification is given; The third step is framework design, through the analysis and design of the application, the special requirements of the application in this field are obtained, so as to extend the framework to achieve the application; Finally, there is the testing of the software. At present, BFD research is more focused on specific fields such as manufacturing, banking, health systems, etc. In terms of development methods, there will be more
