碩士 / 國立交通大學 / 工業工程與管理系所 / 92 / Cognitive overload phenomenon means that computer users suffer from how to catch the contents of huge data at first glance. As a result, visualization technology instead of textual or tabular representations has become more and more significant in the applications of database and data warehouse systems. In this thesis, visualization technology is proposed for solving the cognitive overload phenomenon in Vessel Information Propagating System (VIPS) as more data warehouses are added in recently. Essentially it involves two major improvements. One is the refinement of fishing ground maps for reducing the ambiguity of vessel trails when more data displayed on the map. The other is to add more visual features in the On-Line Analytical Processing (OLAP) part of data warehouse. The empirical study shows the feasibility of this visual approach.
