A MPQF-based multimedia database retrieval system

The MPEG Query Format (MPQF) developed by MPEG Group aims to standardize query interface for multimedia retrieval systems. MPQF is a XML-Based exchange standard which is platform independence, however now MPQF is not directly supported by any database products such as Oracle, DB2 and MS SQL Server. In this paper a MPQF-Based Multimedia Database Retrieval System is designed. The three-tier architecture of system is presented at first, then the paper focus on the key component of the system MPQF SQL Translator which translates MPQF query to SQL code that relational-based multimedia database can evaluate and execute. A case study over MS SQL Server is shown to illustrate the execution.
