Goal

• A Multi-User Object-Oriented Multimedia Database Management System (DBMS) for Information Super-Highway Applications　　

Features and Characteristics

• An Object-Oriented Multimedia DBMS Tightly Coupled with the Text Information Retrieval(IR) System
• The First Object-Oriented DBMS developed in Korea (version 1.0: 1995.7)
• ODYSSEUS/IR (version 2.0: 1997.6)
• Multimedia Database Facilities
• Client/Server Architecture (Windows 98/NT, UNIX client)
• Based on the Multimedia Object Storage System (COSMOS)
• Object-Oriented Query Language (OOSQL with IR Query Extensions)
• Object Buffer Management
• Efficient Management of Multimedia Composite Objects
• Concurrent Access for Multiple Users and Accurate WAL-Based Recovery
• Scientist of the Month Award '98, Korea Science & Engineering Foundation(KOSEF) and Ministry of Science & Technology(MOST)
• Commercialized in the Samsung SDS's Naver Engine (http://www.naver.com)

Application Areas

• Digital Libraries
• IR Systems and Multimedia DBMSs on Intranets
• Home Shopping
• Multimedia Information Servers for Information Super-Highway Applications
• Base Systems for Hypermedia Systems
• Object-Oriented DBMSs for Geographic Information Systems(GISs)
