AbstractHigh speed networking technology has evolved tremendously over the past few years. As a result, network applications which require the transfer of large amounts of data over large geographical areas are now possible using fiber optic networks. One of these such applications is the transfer of color image data at the regional, national, and international levels. ImageNet is a distributed color image database system with multiple database nodes and user workstations linked by a communications network. Each database node serves a number of user workstations within a predefined region. The database nodes are interconnected by a high speed point to point fiber optic network whereas the workstations communicate with the database nodes through a serial link. The work presented here is the design and implementation of the user interface and communication software for a workstation. For development and prototyping purposes, this software was designed to run over an Ethernet network. The results obtained showed that the user workstation software provided the required functionality. We were able to make data dictionary requests, formulate queries, make single and multiple online as well as offline image transfers, and display images.
