An XML-based Solution for Extensible Photograph Database

There is no uniform standard to describe the metadata of photograph presently, and it is usually diffcult to get all the characters of photograph when building a Photograph Data Base(PDB). Therefore, higher extensibility is required for PDB system. In respect of the extensibility of PDB, this paper analyzes the shortcomings of traditional RDBMS and introduces a new solution based on Native XML-Database which uses XML format to describe and store the metadata of photographs. Making use of the extensibility and structural storage of XML, this solution effectively implements the extensibility of the PDB and enables high retrieval capability and cross-platform character of it.
