  2. Java Database Connectivity - Wikipedia

    en.wikipedia.org/wiki/Java_Database_Connectivity

    An example of this is the KPRB (Kernel Program Bundled) driver [16] supplied with Oracle RDBMS. "jdbc:default:connection" offers a relatively standard way of making such a connection (at least the Oracle database and Apache Derby support it). However, in the case of an internal JDBC driver, the JDBC client actually runs as part of the database ...

  3. Java Metadata Interface - Wikipedia

    en.wikipedia.org/wiki/Java_Metadata_Interface

    Given that metadata is a set of descriptive, structural and administrative data about a group of computer data (for example such as a database schema), Java Metadata Interface (or JMI) is a platform-neutral specification that defines the creation, storage, access, lookup and exchange of metadata in the Java programming language.

  4. Data access object - Wikipedia

    en.wikipedia.org/wiki/Data_Access_Object

    Unit testing code is facilitated by substituting a test double for the DAO in the test, thereby making the tests independent of the persistence layer. In the context of the Java programming language, DAO can be implemented in various ways. This can range from a fairly simple interface that separates data access from the application logic, to ...

  5. Hibernate (framework) - Wikipedia

    en.wikipedia.org/wiki/Hibernate_(framework)

    Hibernate ORM (or simply Hibernate) is an object–relational mapping [2]: §1.2.2, [12] tool for the Java programming language. It provides a framework for mapping an object-oriented domain model to a relational database.

  6. Database abstraction layer - Wikipedia

    en.wikipedia.org/wiki/Database_abstraction_layer

    A database abstraction layer (DBAL [1] or DAL) is an application programming interface which unifies the communication between a computer application and databases such as SQL Server, IBM Db2, MySQL, PostgreSQL, Oracle or SQLite. Traditionally, all database vendors provide their own interface that is tailored to their products.

  7. Outline of databases - Wikipedia

    en.wikipedia.org/wiki/Outline_of_databases

    The following is provided as an overview of and topical guide to databases: Database – organized collection of data, today typically in digital form. The data are typically organized to model relevant aspects of reality (for example, the availability of rooms in hotels), in a way that supports processes requiring this information (for example, finding a hotel with vacancies).

  8. SQLJ - Wikipedia

    en.wikipedia.org/wiki/SQLJ

    Parts 1 and 2 are the basis for part 13 of the SQL standard, SQL Routines and Types Using the Java Programming Language (SQL/JRT). "SQLJ" is commonly used to refer to just SQLJ part 0, usually when it is contrasted with other means of embedding SQL in Java, like JDBC.

  9. Object–relational mapping - Wikipedia

    en.wikipedia.org/wiki/Object–relational_mapping

    Object–relational mapping (ORM, O/RM, and O/R mapping tool) in computer science is a programming technique for converting data between a relational database and the memory (usually the heap) of an object-oriented programming language. This creates, in effect, a virtual object database that can be used from within the programming language.
