| Summary: | 碩士 === 國立中央大學 === 資訊工程研究所 === 87 === The demand of applying database technology to laboratory integration environment does exist. There are plenty of workflow, tools, users, documentation and data in the laboratory environment. They could be classified by several different structural properties. Among these classes, the graph structure in the workflow is most difficult to handle with traditional database technique. Lacking of data management and query mechanism, researchers may not be able to learn the work model or to accumulate experience from the great amount of workflow and experiment data.
The goal of this research is to provide an index and query system, which is expected to process various structural data in the laboratory environment. In order to accomplish a uniform object description, we adopt the Object Exchange Model from semistructured data development as the object model of our system. Upon this object model, we could get the best flexibility while developing the system.
We utilize the PAT tree structure of full-text indexing technology for our index kernel. By the PAT tree, full-text query, regular expression query and graph structure query are supported and speedy. The system could communicate with the users through a front end, analyze the query statement, filter out the conflict in the query result from index kernel, and send the correct result back to the users.
The future work of the research includes improving resource utilization of the index kernel, enhancement of user interface and enrichment of query language.
