Design of an interactive data retrieval system for casual users

Among the important criteria in the design and implementation of an interactive data retrieval system for casual users are: a friendly user interface, aids to train beginners on the system, versatility in output media, and error recovery techniques in an interactive session. These factors are considered in the design of an interactive data retrieval system which is used for the study of commodity market data. Although the concepts and considerations discussed in this article are discipline specific, the methodologies adopted are general in nature. The proposed system has been implemented and tested using an experimental data base on gold and silver futures.
