SBA - Opis:
- The paper presents the concepts related to the design of query optimization methods for nested queries. The proposed methods are dedicated for queries having so called weakly dependent subqueries. A subquery is weakly dependent from its direct operator if it depends only on expressions typed by enumerations. We have successfully developed the weakly dependent subqueries method in the context of object-oriented database management systems based on Stack-Based Approach. Systems storing XML data which are queried using XQuery can be considered simplified object-oriented databases. For this reason we try to adopt SBQL query optimization methods to XQuery expressions.
