Grid canvas

This graphically displays all the entities, relationships and attributes for the current project.

Here is an example of what it looks like:

Entity grid item

This is a graphical representation of an entity. It displays the list of attributes for the entity and has an attached relationship grid item for each relationship the entity belongs to.

Clicking the entity name will select that entity. Double clicking the entity name will cause the focus to be sent to the entity details panel.

Clicking an attribute name will select that attribute. Double clicking the attribute name will cause the focus to be sent to the attribute details panel.

Relationship lead grid items will be displayed below selected entity grid items while the mouse is hovered over them.

Relationship grid item

This is a graphical representation of a relationship. It joins two entity grid items which are the parent and child entities for the relationship.

Clicking a relationship grid item will select the associated relationship.

Double clicking a relationship grid item will cause the focus to be sent to the relationship details panel.

You can change the parent and child entities for a relationship by dragging the relationship grid item points attached to the associated entity grid item onto another one.

Relationship lead grid item

These are displayed underneath selected entity grid items when you hover the mouse over them. They allow you to create new relationships for the entity by dragging them onto other entity grid item. If it is valid, a new relationship will be created with the entity that the lead originated from as the parent and the entity it was dropped onto as the child.

The different types of relationship lead grid items correspond to the different relationship types:

Type  Icon  Description
one-to-one Creates a one to one relationship
one-to-many Creates a one to many relationship
