This unit investigates the management of semi-structured data. The unit explores the modelling of semi-structured data in XML using XML Schema and the transformation of such data using XSLT. It looks at methods for storing, querying and updating semi-structured data in both native-XML and object-relational database management systems and the design issues involved.
On successful completion of this unit, students should be able to:
- explain differences between structured and semi-structured data;
- evaluate data management requirements and identify situations that can not be appropriately modeled with the relational data model;
- create data repositories for XML documents by applying the concepts of schemas and namespaces in a case study;
- apply transformation languages for transforming and repurposing XML data;
- apply query languages for navigating and querying an XML data store;
- use current Database Management Systems (DBMS) to store, retrieve and update non-relational data;
- compare and describe strengths and weaknesses of object-relational and native XML DBMS for handling XML.
