{{Note | The length of the fields may vary between databases that are migrated from [[Table differences between migrated and non-migrated databases | Legacy databases and databases]] that were created with {{IMSMANG}} of version 5 or newer.}}
{{Note | [''italic''] will highlight something technical such as {{IMSMANG}} database table name.}}
The Data Dictionary has two different user groups:
* non-technical users
* administratorsand has the ambition to cover both user groups' needs.
There are fields that are shown in the DIM that are of the type calculated fields and they are therefore not included in the Data Dictionary.
