On the detail discussion of database accessing technology, this paper puts forward a database accessing middleware with combination of factory pattern and strategy pattern, andapplying this database accessing middleware in the construction of a deli network trades platform. The actual application shows that this proposed middleware contributes to simplification of code fragment. Moreover, it enhances system extensibility and maintainability through the Factory and Strategy design pattern, and makes data processing more flexible, easier to modify and reuse.
