Hibernate is free software that is distributed under the GNU Lesser General Public License 2.1. 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.
[11] [12] Both input and output parameters must be passed into the database for stored procedures. [13] Update statements such as INSERT, UPDATE and DELETE return an update count indicating the number of rows affected in the database as an integer.

In the above example, the application might supply the values "bike" for the first parameter and "10900" for the second parameter, and then later the values "shoes" and "7400". The alternative to a prepared statement is calling SQL directly from the application source code in a way that combines code and data.
Various methods can be associated with the object, such as methods to return the preferred phone number, the home address, and so on. By contrast, relational databases, such as SQL, group scalars into tuples, which are then enumerated in tables. Tuples and objects have some general similarity, in that they are both ways to collect values into ...

In the SQL 1992 specification, the types of components that can be created are schemas, tables, views, domains, character sets, collations, translations, and assertions. [2] Many implementations extend the syntax to allow creation of additional elements, such as indexes and user profiles.
An object–relational database (ORD), or object–relational database management system (ORDBMS), is a database management system (DBMS) similar to a relational database, but with an object-oriented database model: objects, classes and inheritance are directly supported in database schemas and in the query language.
The Java Class Library (JCL) is a set of dynamically loadable libraries that Java Virtual Machine (JVM) languages can call at run time.Because the Java Platform is not dependent on a specific operating system, applications cannot rely on any of the platform-native libraries.
