Design And Implementation Of Multi Service Oriented Heterogeneous Database Middleware

The development of technology and people’s pursuit of the convenience of life promote the development of a variety of value-added telecommunications services,data services and Internet services,which has made a higher requirement for the management of business data.In practical applications,it is often required to operate a variety of business data at the same time,and these business data may be stored in a number of heterogeneous database.How to manage and operate the heterogeneous database simply and efficiently is one of the important problems to be solved in the business system.In this paper,we design and implement a kind of database middleware server,which can provide centralized database operation and management ability for a variety of business systems.Database operation requested by a client does not need to explicitly indicate the specific target database,but only needs to carry a service attribute information in the request.The middleware server is responsible to submit the data operation requests to the corresponding target business database.It greatly simplifies the database management requirements of the business system.The target business database can be divided into different types by the real-time requirement.The real-time database operations are synchronously completed while the other database operations completed later.It improves the response speed of business database operation.The throughput of the data operation request is also increased significantly by using a large number of pool response processing modes.The interface capability of the middleware server at the same time serving multiple clients has been tested.It supports automatic analysis of the target database and complete the CRUD operations,and the response speed and efficiency of data synchronization to achieve the expected effect.
