1. Comparison and Implementation of Query Containment Algorithms for XPath
Kandidat-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)Sammanfattning : This thesis investigates the practical aspects of implementing Query Containment algorithms for the query language XPath. Query Containment is the problem to decide if the results of one query are a subset of the results of another query for any database. LÄS MER
2. Estimating Query Containment by querying a single database instance
Kandidat-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)Sammanfattning : This paper examines the possibility of simply querying a database as a fast approximation for the query containment problem and measures its accuracy compared with a proper solver. The algorithm for a Correct Query Containment solver, which is used for comparisons sake, as well as the approximative algorithm is laid out. LÄS MER
