Data object creation and display techniques for the huge database of subscriber cable networks

Abstract

Subscriber cable network management systems have huge-scale relational databases. It is difficult to realize a user-friendly data display for theses ystems due to their nonobject data structure. Two techniques are proposed in order to overcome this problem which create dynamic data objects and provide multi-category views. The creation of dynamic data objects is successfully developed by using a special class which manages an array containing data elements of an arbitrary type. The multi-category view system is developed by realizing a multi-category view server which provides several view objects for client applications by object transportation. A complete prototype system based on these techniques is constructed and evaluated. It is confirmed experimentally that a total time of one second is required from the start of data reference to the completion of data object display on a map.
