+/**
+ * A BasicEntityPersiter 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.
