A Comprehension-Based Approach for Query Optimization

摘要：

Comprehensions are a good query notation for database programming languages (DBPLs), which subsume query languages such as SQL and OQL in expressiveness. The AutoMed IQL is an intermediate query language based on comprehensions, which can be used to define the semantic relationships between schemas constructs. In this paper, we emphasize the query optimization problem for IQL queries. Since IQL can be smoothly integrated into several DBPLs, our approach is expected to be applied to semantic web environments.
