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.
