All the functions of the invoicing system are realized by the main program, and the programs and data of each functional module intersect with each other. With the development of the tax industry, the use environment puts forward more and more frequent demands on the function or performance upgrade of the invoicing system. The intervals are getting shorter and shorter. Often the upgrade and development work of one version has not been completed, and the second and third development and upgrade requirements appear. Because of the existing billing system structure and technical solutions, each upgrade development The workload of the work is relatively large and the cycle is relatively long, which has caused delays in the upgrade and development work, and cannot meet the timely needs of solving practical business problems
