In order to create a sound and meaningful sampling plan for estimating measures of database integrity, a statistician must first have appropriate theoretical tools 1. for understanding the nature of databases and their integrity constraints, 2. for developing reasonable numerical measures of database integrity, and 3. for determining the sampling unit and its relationship to the integrity measures. This paper uses database theory, mathematical logic, and sampling theory to provide such tools.
