User-defined table operators are a new concept for object-relational
database systems. They allow users to define functions that have one
or more input tables as input and that produce a result table as
output. Because of the generality of this approach any database
operator can be implemented as the user-defined table operators.
This thesis give information on how user-defined table operators can
be integrated into the database system prototype MIDAS. Furthermore,
some concepts for giving hints to the database optimizer on the
behavior of a user-defined table operator are given. This
information is essential to allow optimization of query plans that
contain such operators.
