Exploitation of World Wide Web to Support Network Updating of Vector ProductFormat Mapping Database at a Feature Level

摘要

This report documents the initial findings and understandings with respect to thedesign of the Object-Oriented Vector Product Format (OVPF) prototype viewer-editor application for: (1) use of commercial hybrID database management systems and (2) the database information update capability over the network. This is a report within the Object-Oriented Database Exploitation within the Global Geospatial Information and Services (GGIS) Data Warehouse project, sponsored by the Defense Mapping Agency (DMA). The primary goal of this project is to investigate, through research and prototyping efforts, the potential impact of object-oriented (OO) technology on DMA's GGIS modernization program. The specific task represented in this report is to address issues and findings involved in supporting database information updating over the network using the OVPF prototype.
