Database rows are mapped to objects (or class instances). You can build data models based on existing data sources or you can build data models from scratch, which you then use to create data structures (tables, columns, joins) in a data source. The result is that database records can be transposed into Java objects.
Although PL/SQL's general syntax formerly used to resemble that of Ada or Pascal, there were many improvements that mainly include the Java embedding code [4] and the object-oriented syntax [5] inside the SQL. The mixing and embedding of triggers and stored procedures was one of the breakthrough points up to support the use of PL/SQL in a OO ...
C++, C#, Java, Python, Smalltalk and XML: SQL superset Proprietary: Distributed, Parallel Query Engine ObjectStore: 7.2 (July 2011) C++, Java, interoperable with .NET SQL subset (also has own object query language) Proprietary: Embedded database supporting efficient, distributed management of C++ and Java objects.
Although this design pattern is applicable to most programming languages, most software with persistence needs, and most databases, it is traditionally associated with Java EE applications and with relational databases (accessed via the JDBC API because of its origin in Sun Microsystems' best practice guidelines [1] "Core J2EE Patterns".
jOOQ Object Oriented Querying, commonly known as jOOQ, is a light database-mapping software library in Java that implements the active record pattern. Its purpose is to be both relational and object oriented by providing a domain-specific language to construct queries from classes generated from a database schema .
The ODMG Object Interchange Format (OIF) was used to dump and load the current state to or from a file or set of files. Object Query Language (OQL). The ODMG OQL was a declarative (nonprocedural) language for query and updating. It used SQL as a basis, where possible, though OQL supports more powerful object-oriented capabilities. C++ Language ...
An object database or object-oriented database is a database management system in which information is represented in the form of objects as used in object-oriented programming. Object databases are different from relational databases which are table-oriented. A third type, object–relational databases, is a hybrid of both approaches. Object ...
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.
