QBD * : a Graphical Query Language with Recursion 1
One of the main problems in the database area is to define query languages characterized by both high expressive power and ease of use. In this paper, we propose a system to query databases, using diagrams as a standard user interface. The system, called Query by Diagram* (QBD*), makes use of a conceptual data model, a query language on this model and a graphical user interface. The conceptual ...
متن کاملStructured Query Language with Recursion
Writing recursive queries for a database is currently a complicated task. The query requires the user to write complex and redundant SQL syntax. Also if the database being used as a backend is not compliant with SQL:1999 then it is not possible to write any recursive queries. In this paper, we present Structured Query Language with Recursion (SQLR), a data retrieval language used for writing re...
متن کاملStructural Recursion as a Query Language
We propose a programming paradigm that tries to get close to both the semantic simplicity of relational algebra, and the expressive power of unrestricted programming languages. Its main computational engine is structural recursion on sets. All programming is done within a "nicely" typed lambda calculus, as in Machiavelli [OBB89]. A guiding principle is that how queries are implemented is as imp...
متن کاملA Graphical Query Language: VISUAL
VISUAL is a graphical query language designed for scientific databases. VISUAL is icon-based and is suitable for domains where visualization of the relationships are important for the domain scientist to express queries. Graphical objects are not tied to the underlying formalism; instead, they represent the relationships of the application domain. VISUAL supports relational, nested, and object-...
متن کاملA Graphical XML Query Language
The structure of aX GLquery consists of two parts: one querying and one constructing XML data graphs. The querying part is defined by means of a simplified form of graph grammar, which is made user-friendly by adding some syntactic simplifications to standard graph grammars. The constructing part is defined by a graph which describes the structure and the content of the document which has to be...
