  1. Query language

    Query languages are computer languages used to make queries into databases and information systems. Broadly, query languages can be classified according to whether they are database query languages or information retrieval query languages. The difference is that a database query language attempts to give factual answers to factual questions, while an information retrieval query language attempts to find documents containing information that is relevant to an area of inquiry. Examples include: ⁕.QL is a proprietary object-oriented query language for querying relational databases; successor of Datalog; ⁕Contextual Query Language a formal language for representing queries to information retrieval systems such as web indexes or bibliographic catalogues. ⁕CQLF is a query language for CODASYL-type databases; ⁕Concept-Oriented Query Language is used in the concept-oriented model. It is based on a novel data modeling construct, concept, and uses such operations as projection and de-projection for multi-dimensional analysis, analytical operations and inference; ⁕D is a query language for truly relational database management systems;
