Data Types

Different programming languages support different inbuilt data types. The Programming Languages Datatypes dialog enables you to extend and manage the set of inbuilt data types associated with a language as well as create new programming languages for use within Enterprise Architect.


  • In the Corporate, Business and Software Engineering, System Engineering and Ultimate editions of Enterprise Architect, if security is enabled you must have Configure Datatypes permission to update and delete data types.
  • You can delete data types that you have defined, but you cannot delete any of the predefined data types.

To access this dialog, select the Settings | Code Datatypes menu option.
