Association (JavaLite - Java, light as a feather 3.0-SNAPSHOT API)

java.lang.Object
- org.javalite.activejdbc.associations.Association

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

BelongsToAssociation, BelongsToPolymorphicAssociation, Many2ManyAssociation, OneToManyAssociation, OneToManyPolymorphicAssociation
```
public abstract class Association
extends Object
implements Serializable
```
Associations are synonymous with relationships. However, in some cases, the DB might have referential integrity constraints. ActiveJDBC does not account for DB referential integrity constraints, associations rather based on conventions and convention overrides.
