Distributed heterogeneous inspecting system and its middleware-based solution
Lican Huang, Zhaohui Wu · 2003
There are many cases where an organization needs to monitor the data and operations of its supervised departments, especially un-owned departments, which are managed by its own information systems. A distributed heterogeneous inspecting system (DHIS) is a system the organization uses to monitor its supervised departments by inspecting their information systems. In DHIS, the inspected systems are generally distributed, heterogeneous, and constructed by different companies. DHIS has three key processes-to abstract core data sets and core operation sets, to collect these sets, and to inspect these collected sets. We present the concept of DHIS, mathematical definition of DHIS, a metadata method to solve the interoperability, security strategy for data transfer, and a middleware-based solution of DHIS. We also describe an example of the inspecting system at Wenzhou custom.
