A user-defined object type is called a custom type and the user-defined properties are called custom properties. Properties are also known as attributes. Custom types can be created, modified, and removed as long as certain rules are followed. This section describes the detail around managing custom types.
A custom type can be created using Documentum Application Builder (DAB), using Documentum Administrator (DA), or using DQL/API scripts. DAB is the most commonly used application for creating custom types since it fully supports the data dictionary (see Data Dictionary later in this chapter) and it has a Graphical User Interface (GUI) specifically designed for creating and managing custom types.
Further, DAB can also be used for packaging the types into a DocApp (DocApps are described in detail in Chapter 10). The following screenshot shows the DAB screen for creating and updating a custom type:
