XML is fast emerging as the standard for representing data in World Wide Web,there are many strategies for storing XML documents and using relational database to storage XML is one kind of these strategies.In order to store the XML data in relational database,mapping DTD to relational schema is studied.Hybrid Inlining is a good approach from mapping DTD to relational schema,it inlines lots of nodes into table,it reduces the number of joining table when we query table,but Hybrid Inlining has some problems when data is deleted or inserted.This paper focuses on mapping scheme to relational schema with Hybrid Inlining,improving Hybrid Inlining so that to solve some problems such as deletion anomaly,insertion anomaly and so on.Lastly,the paper proves it is an approach to having lossless joint and Preserve Data Dependency.
