Conquer-92 Revised Report on the Conceptual Query Language Lisa-d
نویسنده
چکیده
In this report the conceptual query language ConQuer-92 is introduced. This query language serves as the backbone of InfoAssistant's query facilities. Furthermore , this language can also be used for the specification of derivation rules (e.g. subtype defining rules) and textual constraints in InfoModeler. This report is solely concerned with a formal definition, and the explanation thereof, of ConQuer-92. The implementation of ConQuer-92 in SQL-92 will be treated in a separate report.

Conceptual Queries Using ConQuer-II
Formulating non-trivial queries in relational languages such as SQL and QBE can prove daunting to end users. ConQuer is a conceptual query language that allows users to formulate queries naturally in terms of elementary relationships, operators such as “and”, “or”, “not” and “maybe”, contextual for-clauses and object-correlation, thus avoiding the need to deal explicitly with implementation det...
متن کاملConQuer: A Conceptual Query Language
Relational query languages such as SQL and QBE are less than ideal for end user queries since they require users to work explicitly with structures at the relational level, rather than at the conceptual level where they naturally communicate. ConQuer is a new conceptual query language that allows users to formulate queries naturally in terms of elementary relationships, and operators such as “a...
متن کاملAn Algebra for TSQL2
TSQL2 is a declarative query language, and as such, requires a procedural (algebraic) equivalent for implementation. In this chapter, we describe such an algebraic language. We undertook this design in order to show that TSQL2 can be implemented efficiently, with minimal extension of existing techniques. As TSQL2 provides a consistent extension of SQL-92, we had a parallel goal in the construct...
متن کاملOn mapping natural language constructs into relational algebra through E-R representation
Research on accessing databases in natural language usually employs an intermediate form for the mapping process from natural language to database languages However much e ort is needed to bridge the gap between the existing intermediate forms and the database languages In this paper we present a methodology to map natural lan guage constructs into relational algebra through E R representation ...

Deductive Database systems are designed based on a logical data model. Data (as opposed to Relational Databases Management System (RDBMS) in which data stored in tables) are saved as facts in a Deductive Database system. Datalog Educational System (DES) is a Deductive Database system that Datalog mode is the default mode in this system. It can extract data to use outer joins with three query la...
