Abstract
A method for converting relational data to XML (eXtensible Markup Language) is provided. The method can use a greedy algorithm to efficiently construct materialized XML views of relational databases. A greedy algorithm designed for XML view definition queries is provided for decomposing a large query into smaller queries and determining which query will run faster without actually running the query.
