Synthetic retrieval technology for structured data and Non-structured data

A new kind of retrieval software architecture about structured data and Non-structured data was proposed in this paper. In the past, because of the great differences between them, we have to use different ways to deal with their data retrieval. We have been using SQL statements in the structured database search, and using index search in the non-structured data retrieval. But regardless of which search method was taken, it will bring the incomplete problem. Now the architecture resolve the problem.
