CCRelations

In this model we are going to save the relations between Company and Contacts. Since each contacts can belong to more then one Company we've created a pivot Table.

We have only 3 parameters, each one is a ForeignKey for the One To Many Relation. We also added to this table the information about the Type of contacts for each relation Contact / Company.

FIELD NAME	NULLABLE	TYPE	DESCRIPTION
company	False	FOREIGN-KEY	Company ID
contact	False	FOREIGN-KEY	Contact ID
contact_type	False	FOREIGN-KEY	ContactType ID
creation_date	False	DATETIME	Creation Date
