TAILOR is a tool for updating views. It interacts with the database administrator at view definition time to capture syntactic knowledge, structural constraints, and application semantics. It also interacts with the database user and consults the database at view update time to capture additional application semantics and database semantics, respectively. TAILOR uses this information to select from among several alternative update translations against the base relations when the user updates a view. This paper describes an overview of the algorithms used by TAILOR and its implementation using a comprehensive example of a view update and how TAILOR performs it.
