半结构化数据到结构化数据的无损映射
Lossless Mapping from Semi-Structured Data to Structured Data
摘要
Abstract
Most semi-structured data are of certain structure regularity. Having been stored as structured data in relational database (RDB), they can be effectively managed by database management system (DBMS). Some semi-structured data are difficult to transform due to their irregular structures. We design an efficient algorithm and data structure for ensuring lossless transformation. We bring forward an approach of schema extraction through data mining, in which different kinds of elements are transformed respectively and lossless mapping from semi-structured data to structured data can be achieved.关键词
