What Is Data Integrity, and What Are the Qualities of Valuable Information? Because data is used to generate information, many organizations realize that data is one of their more valuable assets. Data integrity identifies the quality of data. Data integrity is important because computers and people use information to make decisions and take actions. For a computer to produce correct information, the data that is entered in a database must have integrity. For information to be valuable, it should be accurate, verifiable, timely, organized, accessible, useful, and cost-effective. Accurate information is error free. Verifiable information can be proven as correct or incorrect. Timely information has an age suited to its use. Organized information is arranged to suit the needs and requirements of the decision maker. Accessible information is available when the decision maker needs it. Useful information has meaning to the person who receives it. Cost-effective information should give more value than it costs to produce.
