Entity Relationship Diagram Conventions

The Siebel logical model represents the following in Siebel Business Applications:

• Entities

• Relationships between entities

ERDs represent the significant entities and relevant relationships in a functional area. To enhance their readability, the diagrams do not include every relationship and subtype. Some many-to-many relationships have also been preserved instead of showing them as one-to-many relationships around intersection tables in the logical model.

This topic describes entity relationship diagram conventions, as follows:

• General Entities

• Exclusive Arc Relationship

• Recursive Relationship
