Relational calculus - The relational calculus refers to the two calculi, the tuple calculus and the domain calculus, that are part of the relational model for databases and that provide a declarative way to specify database queries. This in contrast to the relational algebra which is also part of the relational model but provides a more procedural way for specifying queries.
Object-Relational impedance mismatch - The Object-Relational Impedance Mismatch refers to a set of conceptual and technical difficulties which are often encountered when a relational database is being used by a program written in an object-oriented programming language or style; particularly when objects and/or class definitions are mapped in a straightforward way to database tables and/or relational schemata. This practice has been recommended ...
Object-relational mapping - Object-Relational mapping (or O/RM), is a programming technique that links databases to object-oriented language concepts, creating (in effect) a "virtual object database." There are both free and commercial packages available that perform object-relational mapping, although some programmers opt to code their own object-relational mapping for their systems.
Multiversion concurrency control - In computer science, in the field of databases, multiversion concurrency control (abbreviated MCC or MVCC) is a concurrency control method used in relational databases. A number of relational database management systems (such as Oracle and PostgreSQL) use it to control concurrent access to the database.
Object-Oriented Databases versus Object-Relational Databases - Gives a rough definition of relational, object-oriented and object-relational databases and compares these paradigms using criteria such as simplicity of use, scalability and maturity.
What Is an Oracle Relational Database? - ... records. Illustrates the layout of an Oracle database table. Explains how primary keys keep the records unique. Explains the concepts of a relational database and a foreign key. Describes the common use of lookup tables.

NHibernate in Action : In the classic style of Manning's "In Action" series, NHibernate in Action shows .NET developers how to use the NHibernate Object/Relational Mapping tool. This book is a translation from Java to .NET, as well as an expansion, of Manning's bestselling Hibernate in Action. All traces of Java have been carefully replaced by their .NET equivalents. The book shows how to implement complex business objects, and later teaches advanced techniques like caching and session management. Readers will discover how to implement persistence in a .NET application, and how to configure NHibernate to specify the mapping information between business objects and database tables. Readers will also be introduced to the internal architecture of NHibernate by progressively building a complete sample application using Agile methodologies.
