What Is ADO (ActiveX Data Object)? ADO is an Application Programming Interface (API) to access relational database management systems.
If you want your ASP pages to access your customer relation management (CRM) system, which is running on an Oracle database system, you need to:
1. Install an ODBC driver for Oracle database systems.
2. Create a DSN with ODBC that connects to the CRM system on the Oracle database.
3. Create ADO object in the ASP page, and connect it to the DSN.
4. Using the methods offered by the ADO object to update and query the CRM system.
The following diagram illustrates how an ASP page can interact with an Oracle database:
ASP page <-- ADO --> DSN <-- ODBC --> Oracle database
