Techniques for Indexing Large Numbers of Constraints and Rules in a Database System

  • Akhil Kumar
Conference paper

Abstract

This paper addresses the problem of indexing a large number of rules and constraints in a database system. The objective of such indexing is to be able to quickly identify the relevant constraints and rules, rather than search sequentially, every time insertions, deletions and modifications are made to the database. The constraints are represented as SQL queries which must return null answers. Each constraint is parsed and stored in one or more indexes. Algorithms for index maintenance and constraint retrieval are given.

Keywords

Database System Horn Clause Internal Form Integrity Check Relevant Constraint 
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
