Entities and Objects: Description of Objects: Domain

For technical specifications related domains can be found in the official documentation of PostgreSQL.

The window shown in the figures below, lets you change the properties of an object domain.

As with all objects in a project, the area has a window where you must enter the name of the object, unique within the same project. The window is made up of three folders, grouping in the different logical characteristics of the object

In the first folder "data" are the basic properties of the object. The combo "Type" contains a list of all data types allowed for the release of PostgreSQL selected, and if you position your mouse next to the combo, and if it turns tooltip options in general, you see a brief description the type currently selected.

The second folder is an area where you can enter a description of the object; PostgreSQL provides for almost all objects a property Comment, to allow to document objects.

The last folder, exist in almost all the windows on object-oriented database, appear SQL commands on the building and the construction of instruction takes place in real time, and depends on the settings in the property contained in the current window.
