ODAC 5.1.0.6

不用oracle客户端，直接访问oracle数据库Oracle Data Access Components (ODAC) library offers some nonvisual components for Borland Delphi and C++ Builder. They serve for access to Oracle RDBMS. ODAC is an alternative to standard way processing data by Borland Database Engine (BDE). ODAC uses Oracle Call Interface (OCI) directly. The Oracle Call Interface is an application programming interface (API) that allows an application developer to use a third-generation language‘s native procedure or function calls to access the Oracle database server and control all phases of SQL statement execution. The OCI provides a library of standard database access and retrieval functions in the form of a dynamic runtime library, ORA*.DLL, that can be linked in by the application. Using BDE in Oracle oriented client/server applications has some deficiencies. So in consequence of BDE community get unable server specific features, use more resources, reduce speed of processing data, cumbrous distribution of an application and its administration.
