基于模式映射的GML文档存储
STORING GML DOCUMENTS BASED ON SCHEMA MAPPING
摘要
Abstract
With the wide use of CIS, GML has become the de facto international standard for spatial data encoding, transmitting, sharing and distributing. Recently, with large amounts of GML data appearing in form of the document, how to store and manage them efficiently is becoming a new challenge. In this paper, we propose a storage method based on schema mapping according to the feature of GML documents.Firstly, GML schema is mapped into object-relational database schema according to mapping rules; secondly, GML documents are parsed,corresponding SQL statements will be constructed according to mapping information, and the data is stored to database. Experimental result shows that the storage method brought forward in this paper is feasible and efficient.关键词
