Coverage (information systems)


The Coverage of an Information system is a criterion for the completeness of the records in the information system.
It is defined as the ratio of the number of instances/records in the system that represent real world entities and the number of entities that exist and should be represented in the information system according to its purpose.
Example: If there are 170 countries in the world and an information system holds 153 country records then the coverage of countries of this information system is 90%.
