Abstract

An important component of any data model, particularly a relational one, is the one with which one can specify the conditions to be fulfilled by data in a database. These conditions are called integrity constraints (restrictions). This paper presents the notion of statistical integrity and some integrity indicators with the purpose of generalizing data integrity as a concept. In section 2.2 are described some types of basic integrity constraints that can be specified within a relational model and the integrity mechanisms in DBMSs, and some integrity principles. These mechanisms can help ensuring the correctness of a state by imposing consistency constraints upon information. Consistency constraints also often called integrity constraints or integrity rules in the references.
