Шаблон:More footnotes needed

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 (mostly implemented as a Database) that represent real world entities and the number of entities that exist (in the real world) 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%.
