Code reuse based on information items pool and application in WMS

Distribution center provides necessary logistics service for manufacturers and dealers, and the customers of the manufacturers or dealers usually change frequently. The new customers sometime require the bill of document modification, e.g. add a few information items or drop some items, but the logistics services do not changed, which means the information procedure need not been changed. The information system needs to be modified quickly to meet the need of this type of situation, which needs a lot of code programming work to update the system. This paper brings out a model to reduce the workload by reuse the information procedure program based on information items pool. The information items are separated from the information procedure program, and stored in information items pool XML files, the procedure program obtains the necessary information item message from the information items pool, when running. Only the web page and database are modified by update the information items pool when the system needs update, and the information procedure program need not any modification. This method improves the efficiency of the system development and maintenance by the code reuse.
