Entities and Objects: Description of Objects: Table

For technical specifications on the tables, see the official documentation of PostgreSQL.

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

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 six folders, grouping in the different logical characteristics of the object.

In the first folder "Options" are all properties of the table. The combo "Tablespace" contains a list of all objects tablespace in the project, selecting one, it is docked to the table. It is therefore not possible to give any specific tablespace, in this case, the table will be associated with the tablespace default PostgreSQL.

The second folder "Columns" presents a list of all fields and to schedule allows, through buttons appear, access to information on individual fields of the table. Double-click on a row of active list behaves like an edit button, opening the dialog for editing properties of the field.

The third folder "Indices" presents a list of all the indices on the table, and allows through buttons appear, access to information on individual indices of the table itself. Double click on a line on the list behaves like button amendment, opening the dialog for editing properties of the index.

The fourth folder "Triggers" presents a list of all the triggers linked to the table, allowing through buttons appear, access to information on individual objects. Double click on a line on the list behaves like an edit button, opening the dialog box for editing properties of the object. This mode is added to the standard features of editing trigger, which will be described below.

The fifth tab "Relations" presents a tree-structured list, which displays any reports of the table with the other items contained in the draft. The list is for informational purposes only, and has no function.

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.
