Using Naming Standards

• What is a Naming Standard?

– A glossary of words and abbreviations that can be used in model object names

• Why use the Naming Standards Editor?

– Develop model naming standards

– Check model names for accuracy

– Name model objects in models derived from other models

Using Domains

• What is a Domain?

– A set of values and rules assigned to a data element

• Example: Data types, Validation rules

– Used to quickly assign properties to columns

• Why use Domains?

– Speeds Design process

– Easy to maintain

– Use across entire model

Using User Defined Properties (UDPs)

• What is a UDP ?

– Provides the ability to define custom model object properties

• Why use UDPs?

– Further documentation of model objects

– Clarification for users or viewers of models

– Standardize usage across models

• Examples of Common UDPs

– Data Stewards, Status, Document attachments, etc.

Using Datatype Standards

• What is a Datatype Standards file?

– Includes user-defined datatypes and mapping information that is needed to convert logical & physical datatypes.

• Why use a Datatype Standards file?

– Converting models from Logical to Physical

– Converting models from one Physical DBMS to another

– Deriving multiple models from one source

– Introducing new data types

Using Model Templates with Standards

• What is a Model Template?

– A starting point for new models containing reusable objects such as:

• Domains

• Naming standards

• Formatting options

• Etc.

• Why use a Model Template?

– Provides Standardization and Reuse

– Speeds up development/altering of models/databases
