Study Of Application Programming Interface Technology In Data Mediation System

With the rapid development of Network Technology, people are facing a difficult problem that how to handle rapidly, facilitatly and efficiently with more and more data come from different information sources, especially the current popular relational DBMS with huge amount of datas stored in it. Rearchers have to confront with the problem how to well gather and quickly integrate these information from different sources for Decision Support System, it's also the hot issues in the research field of database.Virtual database integration based on the architecture of Mediator/Wrapper is a main direction in the research of data integration currently. This paper studys and implements the API technology used in the data mediation system:1,In order to make the Front-end applications access the data mediation system seamlessly,transparently and conveniently, this paper designs the mediator JDBC driver which imiates the commercial database JDBC driver.2,Design JDBC driver communication server with Non-Blocking I/O technology to establish the communication between data mediation system and JDBC driver.3,Using the thread pool technology to improve communication module which can allow applications through API make queries to the data mediation system concurrently.
