The Constellation Query Language [PDF]
, 2009 Collaboration in modeling is essential to success, but ORM diagrams intimidate many business people, and most would never install an ORM modeling tool on their computers. The Constellation Query Language (CQL) offers an alternative able to represent almost any ORM2 model in plain text using natural language, with the goal of supporting involvement ...

HyQ, the HyTime query language, provides the answer to situations where you need to specify hyperlinks to locations that may change over time or where a compact notation is preferable to a long location ladder. HyQ queries are similar to database queries, except that they have special facilities for dealing effectively with hierarchical structures like

When storing data in heterogeneous databases, one of the top-down design issues concerns the usage of multiple query languages. A common language enables querying of database schemas in a platform independent format. This is particularly useful in federated database systems when newly added databases may be both numerous and heterogeneous.

Journal of Visual Languages & Computing, 1991
A graphical query language is a visual language which is intended as a database interface and which employs visual metaphors in order to express the semantics of a database language. The TableTalk graphical query language assumes an objectoriented data model and is based upon the notion of a functional query language.

We investigate the expressive power of query languages with counting ability. We define a LOGSPACE extension of first order logic and a PTIME extension of fixpoint logic with counters. We develop specific techniques, such as games, for dealing with languages with counters and therefore integers. We prove in particular that the arity of the tuples which

The social web is becoming increasingly popular and important, because it creates the collective intelligence, which can produce more value than the sum of individuals. The social web uses the Semantic Web technology RDF to describe the social data in a machine-readable way.

Earlier in this book, we learned about repositories, containers for entities of a specific type. They are used to look up entities by specific criteria, do updates or deletes, and so on. They do their work with the help of finder methods, which are implemented using Doctrine’s own entity query language DQL, the Doctrine Query Language.

This chapter presents the query language defined in MULTOS for the retrieval of multi-media documents. The main features of this language is its capability to define conditions on components of the searched documents without specifying the exact types of these documents. The multi-media aspect is enhanced in this language, and conditions can be defined

Any programmer knows that programsmay fall into infinite loops and never terminate. Datalog with constraint programs may have the same problem. When providing library programs for naive users, we need to guarantee that our programs terminate and give a meaningful answer each time they are called and for any possible valid database input. This guarantee
