• How to map a simple and complex domain models in a relational database to the objects developed in Hibernate.
• Role of inheritance when creating an object graph and relational table structure.
• Importance of Hibernate API classes like Session and SessionFactory.
• Mechanisms to store an object with its unique identifier.
• How collections of components can be mapped and used to retrieve data from a relational database.
• Implementing various associations like One to One, Many to One, Many to Many.
• To use lazy fetching and initialization.
• How different collections like Set, Bag or a List can be used to retrieve data from the database.
• How bidirectional relationships can be mapped.
• How to use HQL, JPA QL, Criteria API to fetch data.
• Various states of an object in its persistent life cycle.
• How batch processing improvises the performance when retrieving data.
• Caching of persistent objects in the Hibernate layer including associations, collections and queries.
• Various scopes at which objects can be cached – Transaction, Process, Cluster.
