Tech-clients are stored in the IAM database roughly using the following two-tiered structure:
![Data model](../media/03_Media/XML-Diagrameditor/IAM/Data_model.theme/1.1/en-us.Data_model_html.png)
This data structure is two-tiered with the following intention:
- Tech-client: the principal entity that controls the tech-client including its credentials.
- Credential types: data used to authenticate tech-clients in different ways.
