(In today's enterprise environment, combining object-oriented software with relational databases can be cumbersome and time-consuming. Hibernate is an object / relational database mapping tool for the Java environment. The term object / Relational Mapping (ORM) refers to a technique that maps objects represented by an object model to SQL based relational model data structures.
Hibernate not only manages the mapping from Java classes to database tables (including the mapping from Java data types to SQL data types), but also provides data query and data acquisition methods, which can greatly reduce the time for manual SQL and JDBC processing and the data in the development process.
The goal of Hibernate is to free 95% of the data persistence related programming tasks commonly used by developers. For data centric programs, only stored procedures in the database are often used to implement business logic, and Hibernate may not be the best solution; For those Java based middle tier applications that implement object-oriented business models and business logic applications, hibernate is the most useful. Either way, hibernate can definitely help you eliminate or wrap vendor specific SQL code and help you transform result sets from tabular representations to a series of objects.
If you are new to hibernate and object / relational database mapping, or even to Java, please follow these steps.)
