# Documentation: Test Metadata DbRecord Classes

## 1. Purpose

This module provides three entity classes—`TestEngineerDetailsDbRecord`, `CustomerDetailsDbRecord`, and `LabratoryDetailsDbRecord`—that model persistent test metadata records for test engineers, customers, and laboratories respectively. Each class serves as a data transfer object (DTO) that implements property change notification, supports instantiation from database readers via `IDataReader`, and provides copy construction for cloning. These records appear to be part of a larger test management system where metadata about test participants is stored and tracked with versioning and audit information.
