A comprehensive study of object-relational queries gives not only an understanding of full capability of object-relational query language but also a direction for query processing and optimization. This chapter classifies object-relational queries into REF queries, aggregate queries and inheritance queries. REF queries are queries involving REF pointers, whereas aggregation queries use either nested table structures or index on clusters. Finally, inheritance queries are queries on inheritance hierarchies.
