Using data dictionaries

In typical functional and logical design activities, key building blocks or components of the designs are reused to save time and effort. To facilitate reuse of these building blocks or components in multiple designs, across several projects or programs, Teamcenter provides a central organizational repository for them.

These repositories are referred to as data dictionaries. A data dictionary is modeled in the Classification perspective as a library. The Classification administrator builds a customer-specific hierarchy under one or more libraries for organizing data, for example, signals and interfaces.

Depending on access privileges, you can then:

• Create, modify, and delete data from the dictionary.
• Associate a project or program with one or more dictionaries. Typically, the product design data is also associated with the same project or program.
• Search the dictionary for data meeting specified criteria.
• Add data from the dictionary to a functional, logical, or physical breakdown.
• Create signals in structures and associate them with interfaces and connections.

Note: A default Signals library type is provided and can be used by the Classification administrator to add a signals library and data dictionary to the classification hierarchy. Your Classification administrator can also create other libraries suited to your business needs, for example, a library of functions.
