Data Types

Every Table column that you define in your data model has a data type assigned that specifies the type of information that can be stored by the column. The available datatypes for a column are dependent on the selected DBMS for the Table, because each DBMS supports its own list of datatypes. Whilst each DBMS supports the same basic types, such as string, whole or decimal numbers, each DBMS calls them by different names and have different properties.

Each Enterprise Architect repository contains the definitions of the core datatypes for a number of standard DBMS products. However, since data types vary from one DBMS product to another, and from one version of a product to another, Enterprise Architect provides you with tools to:

  • Define new data types for a new version of your DBMS product
  • Define data types for a new, non-standard database product
  • Automatically convert data types from one defined DBMS product to another
  • Import and export datatypes between repositories
