DRDA enables network-connected relational databases to cooperate to fulfill SQL requests.
See navigational database and NoSQL for alternatives to the relational model.
A distinction should be made between alternatives to SQL as a language, and alternatives to the
relational model itself. However, extensions to Standard SQL add procedural programming language functionality,
such as control-of-flow constructs. Interested parties may purchase the standards documents from
ISO, IEC, or ANSI.
