ABSTRACT
With the advent of the Extensible Markup Language (XML) as a standard for data representation and exchange on the Internet, the presence of XML data becomes more prevalent than ever in the scientific and engineering research communities as well as business sectors. To establish a public microarray gene expression database, as an example, the most challenging problems are annotating microarray experiments in a standardized and machine-readable way, and developing normalization procedures and standards enabling the comparison of data from different experiments possibly performed on different experimental platforms. Understandably, the current consensus is that standards for storing and annotating data be developed based on the XML technology.There are important technical challenges in establishing XML databases, and indexing and querying XML data. First, as opposed to highly structured relational databases, XML data are intrinsically semi-structured. Second, new indexing and query processing strategies are needed for the use of regular path expressions, which is the common feature of the most XML languages to query XML data. Third, the query optimization for XML data still remains largely unexplored. In the past few year, several promising strategies have been proposed to rise to those challenges. We will overview the work done or in progress for mapping XML data to and from the relational model, indexing and querying XML data for path expressions, selectivity estimation for XML queries, and versioning XML documents. We will then discuss the general research issues and future directions.
