Graphical Querying of Model-Driven Spreadsheets

摘要

This paper presents a graphical interface to query model-driven spreadsheets to simplify query construction for typical end-users with little to no knowledge of SQL. This was based on experience with previous work and empirical studies in querying systems. We briefly show our previous text based model-driven querying system. Afterwards, we detail our graphical model-driven querying interface, explaining each part of the interface and showing an example. To validate our work, we executed an empirical study, comparing our graphical querying approach to an alternative querying tool, which produced positive results.
