Interface and Data Architecture for Query preview in Networked Information Systems

摘要

There are numerous problems associated with formulation queries on networked information systems. These include increased data volume and complexity, accompanied by slow network access. This article proposes a new approach to a network query user interfaces that consists of two phases: query preview and query refinement. This new approach is based on the concepts of dynamic queries and query previews, which guides users in rapidly and dyanmi- cally eliminating undesired records, reducing the data volume to a manageable size, and refining queries locally before submission over a network.
