Adding Entities and Attributes

An entity is a table-like construct that contain one or more attributes. An attribute, in turn, represents a single field from the database. You will use entities and attributes to create a business-friendly view of the database schema.

To create a new entity, use one of the following methods:

1. Right-click an empty region of the logical model panel, and select 'New Entity' from the context menu. This opens the 'Entity Wizard', where you can enter a name for the new entity.

 

2. Drag a table from the physical view panel into the logical model panel. This adds a new entity containing all of the table fields as attributes. (Expand the entity node to see the attributes.)

 

To search for a table, see Sorting and Filter­ing a Physical View.

To add an attribute to an entity, drag a field from the View panel onto the desired entity. (Expand the entity node to see the component attributes.)
