/**
* A BasicEntityPersister maps an entity to a single table in a relational database.
*
* A persister is always responsible for a single entity type.
*
* EntityPersisters are used during a UnitOfWork to apply any changes to the persistent
* state of entities onto a relational database when the UnitOfWork is committed,
* as well as for basic querying of entities and their associations (not DQL).
*
* The persisting operations that are invoked during a commit of a UnitOfWork to
* persist the persistent entity state are:
*
* - {@link addInsert} : To schedule an entity for insertion.
* - {@link executeInserts} : To execute all scheduled insertions.
* - {@link update} : To update the persistent state of an entity.
* - {@link delete} : To delete the persistent state of an entity.
*
* As can be seen from the above list, insertions are batched and executed all at once
* for increased efficiency.
*
* The querying operations invoked during a UnitOfWork, either through direct find
* requests or lazy-loading, are the following:
*
* - {@link load} : Loads (the state of) a single, managed entity.
* - {@link loadAll} : Loads multiple, managed entities.
* - {@link loadOneToOneEntity} : Loads a one/many-to-one entity association (lazy-loading).
* - {@link loadOneToManyCollection} : Loads a one-to-many entity association (lazy-loading).
* - {@link loadManyToManyCollection} : Loads a many-to-many entity association (lazy-loading).
*
* The BasicEntityPersister implementation provides the default behavior for
* persisting and querying entities that are mapped to a single database table.
*
* Subclasses can be created to provide custom persisting and querying strategies,
* i.e. spanning multiple tables.
