Application Information Metamodels (AIMs)
How metadata is stored in the repository is defined by Application Information Metamodels
(AIMs).
An AIM consists of:
Classes, which are types of metadata objects
Properties, which are data fields associated with a particular class
Relationships, which are associations between two classes
The three AIMs supplied with Teradata MDS are:
Teradata Database Information Metamodel (DIM) – is a predefined AIM for storing the Teradata Data Dictionary information from Teradata
databases and associated business data.
Client Load Metamodel (CLM) – is a predefined AIM for storing the information obtained from Teradata client FastLoad,
MultiLoad and TPump utility scripts and output files.
Common Warehouse Metamodel (CWM) – is a predefined AIM for storing information obtained from supported business intelligence
tools.
These AIMs can be extended or entirely new AIMs can be created to store other metadata
in the MDS repository.
