A method to design domain specific software framework is put forward

which is based on analysis on traditional business operations and generalization of simple application frameworks.Core operations and accessory operations are recognized in traditional business operation processes

and the operations are formalized and simplified in order to form a simple single-functioning application framework

which can be extended to the whole domain by comparison and generalization with other frameworks on the same core operations.The main point of this method is to build up a comparatively simple but effective application framework before a more complex and generalized domain framework can be constructed.
