【Abstract】 The paper applies the strategy pattern to study the use of the stored procedure of the return data result set at the front end of the high-level module. Under the design of strategy pattern, each stored procedure call is treated as a strategy, and each strategy is a class, to achieve the abstraction of the upper to the strategy family. With a detailed analysis of the two types of storage processes(with and without parameters), we design the class diagram and realize the use of the pettern to further improve the system’s reusability and maintainability.更多还原
