Completeness - definitions

Completeness : A characteristic of information quality measuring the degree to which all required data is known. (1) Fact completeness is a measure of data definition quality expressed as a percentage of the attributes about an entity type that need to be known to assure that they are defined in the model and implemented in a database. For example, "80 percent of the attributes required to be known about customers have fields in a database to store the attribute values." (2) Value completeness is a measure of data content quality expressed as a percentage of the columns or fields of a table or file that should have values in them, in fact do so. For example, "95 percent of the columns for the customer table have a value in them." Also referred to as Coverage. (3) Occurrence completeness is a measure of the percent of records in an information collection that it should have to represent all occurrences of the real world objects it should know. For example, does a Department of Corrections have a record for each Offender it is responsible to know about? (IQ).
