Design Editor

The Design Editor is a graphical user interface where you can view your database objects and their relations as graphical objects. A table including its columns, indexes, keys, and constraints is displayed in a so-called table design (see Viewing Table Structure). You can add new tables or edit existing ones or just drag a table into a Design Editor window to see what its structure looks like.

Design Editor

When you add new objects (e.g., tables or columns) to Design Editor or change the structure of existing ones, these changes are not immediately effective in the database. Any changes in the database design are recorded in the Database Structure Change Script and can then either be executed or rejected.

 

When you right-click in an unoccupied area of the Design Editor, several general options are available in the context menu which are listed below. The corresponding Toolbar icons are shown to the left, and keyboard shortcuts to the right of the options if they are available.
