Design a visual database structure
To design your database visually you may use the Visual Database Designer. It allows you to create, edit and drop tables and table fields, set relations between tables and perform other operations you may need to achieve your purpose.
To create a new object right-click within the diagram area and then choose the Create item of the context menu. After that a new object will appear on a diagram.
After you have finished designing your diagram you can click a Compile button to create this structure physically.
