Data integrity is enforced via the Data Model, and therefore dictated by client's requirements.

A comprehensive error reporting tool provides guidance for users. Invalid records are retained in a temporary table for corrections and subsequent entry to the database.

DataShed offers a downhole interval validation tool for those clients who wish to allow invalid intervals into the database and to validate the data at a later stage. This tool checks for overlapping intervals, missing intervals, duplicate intervals and intervals past the specified maximum depth in the collar table.
