Construction of a reusable data access layer based on .NET

1 Introduction 1 In the course of software development, the architecture design of software system plays a key role all the time 1]. For large enterprise application, the system architecture can influence not only the system design and the system development, but also the follow-up development of the system directly. It can even determine whether the whole system development is successful. Currently, because of its obvious advantages , N-tier architecture has already become a standard of str…

Construction of a reusable data access layer based on .NET

A new design solution of data access layer for N-tier architecture is presented. It can solve the problems such as low efficiency of development and difficulties in transplantation, update and reuse. The solution utilizes the reflection technology of .NET and design pattern. A typical application of the solution demonstrates that the new solution of data access layer performs better than the current N-tier architecture. More importantly, the application suggests that the new solution of data access layer can be reused effectively.
