public abstract class DatabaseMapping extends CoreMapping<AttributeAccessor,org.eclipse.persistence.internal.sessions.AbstractSession,org.eclipse.persistence.internal.queries.ContainerPolicy,ClassDescriptor,org.eclipse.persistence.internal.helper.DatabaseField> implements java.lang.Cloneable, java.io.Serializable
Purpose: Defines how an attribute of an object maps to and from the database
Responsibilities:
- Define type of relationship (1:1/1:M/M:M/etc.)
- Define instance variable name and fields names required
- Define any additional properties (ownership, indirection, read only, etc.)
- Control building the value for the instance variable from the database row
- Control building the database fields from the object
- Control any pre/post updating/inserting/deleting required to maintain the relationship
- Merges object changes for unit of work.
- Clones objects for unit of work.
- cache computed information to optimize performance
