Abstract


With the increasing development of information technology, more and more industries with information technology management through information technology and tools to increase productivity and management efficiency. Therefore, the demand for information systems increasingly large. At the same time, information systems development as a discipline with technological advances in the constantly developing. The development of the information systems are increasingly moving in the direction of the hierarchical forward. At all levels of the system development more specialized, the difference between the levels clearer, more detailed. In the development of information systems, database operations layer has been a very important part, it can be said that any enterprise-level information systems must be involved to this level. So many organizations for this to develop a lot of targeted technologies, such as Java Database Connectivity (JDBC), and Object-relational mapping (ORM), etc., used to improve the efficiency and simplify this part of the operation in this regard. System developers can be more energy to focus on the work of the man-machine interface and service control logic. Brief analysis, analysis of its main advantages and disadvantages of existing mainstream technology in this regard. Efficiency and ease of use for its shortcomings, try to try optimization. And based on a reflective technology related patterns of design ideas. Which first introduced the concept of reflective technology, the second section describes the basic principles of reflective technology to simplify database operations. Subsequently given a preliminary model. Detail during the initial implementation of the core interface and core functionality, specific and important function by analysis and class. On this basis, combined with the development of the actual system, demo mode applications. First introduce the background of the system, and starting from the perspective of many aspects of the system, such as security, stability, etc., and briefly describes the system design ideas for these areas. After focusing on a module system demonstrates the use of the model and the resulting benefits. Concludes with a description of the actual operating efficiency of the the reflection operation mode system, summed up the experience in the development process, and depending on the application, to determine the next step mode to achieve the optimization direction.
