A relation defines a relation between two tables. One or more records in the first table belong to one or more records in the second table. A one to many relation would be '1 library has N books'. Below is a list of the relations that are currently available in ATK.
- atkOneToOneRelation - 'A person has one address'
- atkOneToManyRelation - 'A department has many employees'
- atkManyToOneRelation - 'A project has a projectleader (that can lead multiple projects)'
- atkManyToManyRelation - 'A shopper buys multiple products, a product can be bought by multiple shoppers'
- atkManyBoolRelation - 'An article has several categories, selected from a list of categories'
- atkManyToOneTreeRelation - 'A category has a parent category'
