Proceedings 2001 International Database Engineering and Applications Symposium, 2002
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.

Hybrid LLM: Cost-Efficient and Quality-Aware Query Routing
International Conference on Learning RepresentationsLarge language models (LLMs) excel in most NLP tasks but also require expensive cloud servers for deployment due to their size, while smaller models that can be deployed on lower cost (e.g., edge) devices, tend to lag behind in terms of response quality.

Computational Power in Query Languages
SIAM Journal on Computing, 1982Primitive recursion, recursion and partial recursion are defined for languages which query a relational data base. Necessary and sufficient conditions for a language to satisfy these properties are given. The computational power of several extensions of the relational algebra is considered.

IEEE Transactions on Knowledge and Data Engineering, 1993
We define the query language Vizla, in which answers to queries are built up by pointing to representations of sets and functions in a conceptual model of the data base of an application, and to iconic identifiers of computational operators or control constructs.

The t4sql temporal query language
Proceedings of the sixteenth ACM conference on Conference on information and knowledge management, 2007Time characterizes every aspect of our life and its management when storing and querying data is very important. In this paper we propose a new temporal query language, called T4SQL, supporting multiple temporal dimensions of data. Besides the well-known valid and transaction times, it encompasses two additional temporal dimensions, namely ...

A coherent query language for XML
Journal of Intelligent Information Systems, 2008Text search engines are inadequate for indexing and searching XML documents because they ignore metadata and aggregation structure implicit in the XML documents. On the other hand, the query languages supported by specialized XML search engines are very complex.

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.

A multimedia query specification language
Proceedings. International Workshop on Multi-Media Database Management Systems, 1996Typically, multimedia applications involve thousands of hours of video, images, audio, text and graphics that need to be stored, retrieved and manipulated in a large multimedia database. There is therefore an important need for novel techniques and systems which provide an efficient retrieval facility of the voluminous information stored in the ...
