HIBERNATE RELATIONAL PERSISTENCE FOR IDIOMATIC JAVA PDF

Hibernate ORM or simply Hibernate is an object-relational mapping tool for the Java programming language. It provides a framework for mapping an object-oriented domain model to a relational database. Hibernate handles object-relational impedance mismatch problems by replacing direct, persistent database accesses with high-level object handling functions. Hibernate's primary feature is mapping from Java classes to database tables , and mapping from Java data types to SQL data types. Hibernate also provides data query and retrieval facilities.

Hibernate: Object /Relational Persistence for idiomatic Java

Working with object-oriented software and a relational database can be cumbersome and time consuming in today's enterprise environments. Hibernate not only takes care of the mapping from Java classes to database tables and from Java data types to SQL data types , but also provides data query and retrieval facilities and can significantly reduce development time otherwise spent with manual data handling in SQL and JDBC. Hibernates goal is to relieve the developer from 95 percent of common data persistence related programming tasks. Hibernate may not be the best solution for data-centric applications that only use stored-procedures to implement the business logic in the database, it is most useful with object-oriented domain models and business logic in the Java-based middle-tier. However, Hibernate can certainly help you to remove or encapsulate vendor-specific SQL code and will help with the common task of result set translation from a tabular representation to a graph of objects. From a command prompt in the distribution directory, type ant eg using Ant , or under Windows, type build eg.
