Abstract
To support emerging database applications,
object-relational databases leverage the mature
relational database technology and allow users
to introduce application-specific types and methods.
Tables in a database may now contain such objects as
geographical shapes, images, and text documents. To realize
the full potential of object-relational databases, efficient
querying and searching of user-defined objects must be supported.
This paper presents a high level framework for indexing of
user-defined types with user-defined predicates. It is orthogonal
to the low level access methods that are supported. It is unique
in providing direct user control over the transformation from a
user-defined type into an abstract domain of index values, the
generation of search keys of a user-defined predicate with
bound search arguments, and the execution of a user-defined
predicate. The high level framework has been implemented in IBM
DB2 Universal Database. Its generality, usability, and performance
have been demonstrated in different application domains, where
indices on user-defined objects can be fully integrated with
SQL queries and exploited by the query compiler.
