C++ API Classes - Teradata Meta Data Services

C++ API Classes

MDS provides a C++ class library to access the MDS repository. The MDS repository is a set of tables within a Teradata Database specifically designed to manage meta data, and is created for you when you run the Create MDS Repository function after installing the MDS software. The C++ class library allows users to programmatically create application information metamodels (AIMs) to update and delete meta data objects, and to access collections of objects in the repository.

The following is a summary of the C++ classes available in the library. These APIs are described in detail in this document.
