F-metric: a WWW-based framework for intelligent formulation and analysis of metric queries

Conceptual Modelling of Database Applications Using an Extended Er Model H.2.1 Database Management] Logical Design { Data Modelss Schema and Subschema. H.2.3 Database Management] Languages { Data Description Languages (ddl)) Data Manipulation Languages (dml))

A data model for conceptual design of structural and behavioural aspects of databases using a descriptive logic based query language for the EER model and emphasizing that the various aspects of a database application are speci ed using several appro priate but yet compatible formalisms which are integrated by a unifying common semantic CR.

High Level Database Interface with Application to GIS

A compiler system, which given a database model can compile constraints formulated in hlcl to a directly executable sql query and well-defined datalog interface is described, which is implemented in prolog and tested with actual constraints from the Geographic Information Domain.

Design of Flexible Static Program Analyzers with PQL

  • 1998
The author describes a program query language, called PQL, that facilitates the design of flexible SPAs, that is a conceptual level, source language-independent notation to specify program queries and program views.

The effect of data model, system and task characteristics on user query performance: an empirical study

An empirical study is reported on that investigates the effect of entity-relationship versus relational models, and textual versus visual query languages for user-database interfaces.

Model-based design of tools for business understanding and re-engineering

  • 1995
A design scenario for business understanding and re-engineering tools that is based on the systematic modeling of business knowledge, including an interview assistant tool, support for impact analysis, and an end-user query language in which a user can define new business analysis methods that are not supported by a generic tool environment.

Fundamentals and Pragmatics of an Entity-Relationship Approach

This text presents a comprehensive introduction to an extended Entity-Relationship model both on a conceptual and on a formal, mathematical level and introduces a language for the formulation of constraints in order to restrict database states to consistent ones.

Eine SQL-ähnliche Anfragesprache für das EER-Modell

Der Entity-Relationship-Ansatz zeichnet sich wie kaum ein anderes Datenmodell durch eine Vielzahl an Anfragesprachen unterschiedlicher Couleur aus, die eine einfachere und naturlichere Formulierung

User-Database Interface: The Effect of Abstraction Levels on Query Performance

The huge differences indicate that noticeable improvements can be made by switching from the relational model to the ER model and the experiment also provided valuable data on errors commonly made by users.

Natural Language Restatement of Queries Expressed in a Graphical Language

The result of this work has been the individuation of general criteria to obtain natural languages restatements from a single query expressed in a graphical language on Entity-Relationship schemas.
