Research and application of metadata in information management

Being aimed against to the software reusability and interoperability, we design a metadata-driven information management system. when developing a new application, we can search quickly, locate, and reconstruct on existing IT resources by meta-data description, discovery, mapping and conversion. In the three-tier architecture based on the SSH, we implement B/S model of information management systems by means of entity metadata description and deployment, data Access Services. Experimental results show the design is effective and feasible.
