An Implementation of Wrapper Using JDBC under CORBA Frame
Xie Rong-chuan · Microcomputer Development · 2004
Implements a wrapper that can access all kinds of databases in the network.It acts CORBA Server,which encapsulates JDBC inside and provides the same interface as JDBC API outside,as agent using object-wrapped technology of CORBA.It achieves the transparence of network and the independency between client and CORBA Server due to CORBA and OMG IDL techniques.Furthermore,thanks to JDBC technique,it has a better expansibility of connecting more kinds of databases as long as other JDBC driver programs are increased in this system.The wrapper that introduced need not design one wrapper according to one kind of database.We can implement it as long as we encapsulate JDBC driver programs inside the wrapper and supply metadata of all kinds of databases in the Metadata Object.
