Visual Query System (VQS)

Introduction

Visual query interface is a key factor in lowering the treshold at which end users are able to express their adhoc searches.VQS is making querying independant of end users’ skills and knowledge of the underlying textual query language and the structure of data.

Internal querying language and data structure is abstracted behind a representative model -the ontology- of the end-user domain. The familiar vocabulary and structure of this ontology combined with the user-friendliness of graphical query building gives the end-user an unpreceeded ability to build complex queries by himself.

Resource: Optique VQS Demo Video (Apr 2014)

This video from the Optique YouTube page gives a demo of the Optique VQS. It first gives a brief overview of the interface, and then it shows how to construct an example query.

Warning: The video is from 2014, so there is a significant difference between the version used in the video, and the newest version of Optique.

Resource: Northwind Public Demonstrator

The Northwind public demonstrator allows users to test the Optique VQS on the Northwind setup. This is the best easiest way to test the interface yourself.

Optique: a paradigm shift for data access

The project will provide a semantic end-to-end connection between users and data sources. The Optique platform will feature an intuitive, general, but adaptable end-user interface. Data can be integrated from multiple, also streaming, data sources, with the possibility for large-scale parallel cloud processing and storage.

Optique: a unique combination of technologies

The Optique project brings a unique combination of technologies to bear on Big Data challenges: An end-user-oriented query interface; scalable query rewriting from the end-user to the source vocabulary; temporal and real-time continuous stream processing; scalable storage and query evaluation using elastic clouds.
