This paper discusses data integrity and how it assists in making information systems reliable systems. The paper also shows that data integrity is one of the primary means of establishing, enforcing, and ensuring the effectiveness of information systems. In addition, the paper addresses the different categories of data integrity that help in ensuring information systems' effectiveness. This class of effectiveness is implemented through information systems databases. Information systems facilitate both the distribution of information (information sharing) and decision-making practices to accomplish users' goals. Information systems are used to (a) fulfill users' information needs, (b) control organizations current activities, and (c) predict future management expectations. The reliability of information systems is in most part controlled by the databases from which the systems' information is generated. The databases on which information systems rely must have integrity for the information systems to be deemed effective to the accuracy and correctness of the information they produce. Databases without data integrity are bound to store erroneous data, therefore making the information systems they serve undependable. Data integrity is a measure for enforcing data consistency, accuracy, and completeness within the databases of information systems. In other words, data integrity establishes and maintains correctness of data in databases. Data integrity ensures that the integrities of the databases are enforced and that users' information requirements are satisfactorily met. Databases must meet the data integrity requirements for the information systems they serve to be productive. Data integrity is all about the correctness of data rather than security measures.
