![]() Application-level conversations that span over multiple web requests.For instance, aside from the typical object-relational mapping feature, Hibernate also implements the following data access patterns: Hibernate is a data access framework implementing many patterns that have been popularized by Martin Fowler in his book Patterns of Enterprise Application Architecture. However, Hibernate is more than an ORM framework that conforms to the Java Persistence API specification. The object-relational mapping (ORM) pattern aims to address this problem, and Hibernate ORM is undoubtedly one of the most successful implementations of this pattern. ![]() The discrepancy between graph-like structures and database tuples is typically known as the object-relational impedance mismatch. ![]() When using an object-oriented programming language, the object graph becomes the most natural representation of data. While the database is responsible for storing and retrieving data, the business logic is usually embedded in the application layer. In a relational database, data is stored in table rows, and relations are expressed through a foreign key.
