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.

XML data is different from data found in relational databases in several important respects. The article discusses these differences and why they justify development of a new query language for XML. It also reports on the activities of the W3C working group on XML queries.

Once upon a time, 64KB came in a piano crate, not on a small chip, and maintaining and manipulating data was expensive. Memory wasn’t the only problem: software was in its infancy, and simple tasks such as storing and indexing files required lots of support staff. As data grew, so did the need for better ways to maintain and manipulate that data.
