Effective Apply of Design Pattern in Database-Based Application Development

In the design of database-based application, effective use of object-oriented programming methodology to optimize the database access code is related to the structure and maintainability of the entire application. Without proper optimization of the access code will cause significant incensement of the degree of coupling between modules, and increase the cost of application maintenance. This paper discusses how to effectively apply thoughts of Design Patterns and technique of Object Oriented Programming to construct the database applications, which will be made to well formed, easy to understand and maintain. Practice has proved that effective apply of appropriate design patterns make database application structure be easy to understand, thereby greatly improve the scalability and maintainability of the whole application.
