ORM articles and products

ORM is used to map object-oriented programming objects to relational databases managed by Oracle, DB2, Sybase, and other relational database managers (RDBMSs). This site provides facts about ORM products, architecture problem-solving, and direction in product comparison and selection.

ORM products are designed to work with object programming languages such as C#, C++, and Java. Database objects appear as programming language objects. Often, the interface for ORM products is the same as the interface for object-oriented databases.

An ORM product likely will reduce your programming code and, through caching, improve performance over using an embedded SQL or call-level interface such as JDBC or ODBC when using an RDBMS. The performance cost of using RDBMSs with objects can be reduced because most ORM products provide transparent persistence with object programming languages and caching. More on these topics can be found in the articles mentioned in the next section.
