Relational database management system

1 A relational database management system (RDBMS) is a database

management system (DBMS) that is based on the relational model as

introduced by E. F. Codd, of IBM's San Jose Research Laboratory. Many

popular databases currently in use are based on the relational database

model.


Relational database management system - Historical usage of the term

1 For clarification, they often refer to some RDBMSs as Truly-Relational Database Management Systems

(TRDBMS), naming others Pseudo-Relational Database Management

Systems (PRDBMS).

Comparison of relational database management systems

1 The following tables compare general and technical information for

a number of relational database management systems. Please see the individual products' articles for

further information. Unless otherwise specified in footnotes, comparisons

are based on the stable versions without any add-ons, extensions or

Comparison of relational database management systems - Fundamental features

1 Comparison of relational database management systems#feat 1|Note (1): Currently only supports read

uncommited transaction isolation. Version 1.9 adds serializable isolation

and version 2.0 will be fully ACID compliant.

through MySQL Workbench.


Comparison of object-relational database management systems

1 This is a 'comparison of object-relational database management

systems' (ORDBMSs). Each system has at least some features of an

object-relational database; they vary widely in their completeness and the

approaches taken.


Object-relational database management system

1 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. In addition, just as with pure relational systems, it supports extension of the data model with custom data type|data-types

and method (computer science) |methods.
