Song Liu · Jilin Normal University Journal · 2011
Aimed at the urgent needs of integrating heterogeneous data resources for most college campus,the paper gived a practical solution based on design patterns.Facade design pattern provided a consistent interface of accessing the heterogeneous database resources of the campus application subsystem and made the data access layer more flexible.Singleton design pattern improved the efficiency of processing data resource in the database,and enhanced the stability of the system.The solution had many adantages,such as development language-independent.It made the data access layer more flexible,and improved the portability and scalability of system.
