Introduction

• Why store XML documents?
• Why use an RDBMS?

3
Some issues

• Mapping to relational data model
• Lossless Mapping
• Handling XML queries
• Reconstruction of XML documents

4
Some proposed methods

• 1. An efficient data extraction and storage
  utility for XML documents
• 2. Relational databases for querying XML
  documents Limitations and opportunities
• 3. Storing and querying XML using an RDBMS
• 4. Storing semi-structured data with STORED

5
Systems overview

• Method 1
• Use of DTDs
• Manual schema translation
• Provides for filtering
• Lossless mapping
• Method 2
• Use of DTDs
• Automatic schema translation
• Lossless Mapping
• XML view of database

6
Systems overview

• Method 3
• No use of DTDs
• Lossless Mapping
• Method 4
• Use of DTDs
• XML view of database
• Lossless Mapping

7
Objectives

• Implement additional features that aim for the
  enhancement of method 1 such as
• Automatic schema translation technique
• XML view of database

8
