Using materialized view to accelerate OLAP queries is one of the most common methods used in ROLAP systems. However, high storage and computation cost make this method very diffic...
Many algorithms have been proposed in the area of materialized view maintenance. They provide different capabilities and features, and have different complexity in their implement...
Abstract. This work discusses the CROQUE approach to the maintenance problem for materialized views. In a CROQUE database, application-speci ed collections (type extents or classes...
Materialized views which are derived from base relations and stored in the database are often used to speed up query processing. In this paper, we leverage them in a traceable peer...
Semistructured data is not strictly typed like relational or object-oriented data and may be irregular or incomplete. It often arises in practice, e.g., when heterogeneous data so...
