Research on Database Middleware and Its Application in AES

Database technology is a hotspot in the field of computer applications. Using database middleware technology in software development can improve software quality and efficiency. This paper introduces two database middleware technology ODBC and JDBC specifications, and puts these technologies to use in communication interface between agriculture expert system(AES) and database respectively. Knowledge base calls different databases in the same way, it solutes the problem of inconsistency and enlarges the scope of Knowledge acquisition. Finally makes a comparison between them.
