tenant_idDescription: The table contains contact/member records. Each row represents a contact with its detailed attributes flattened into dedicated columns — identity and profile fields (names, email, phone, address), membership and marketing metadata, and registration/creation timestamps. This data can be used for:
- building a single reliable contact list for personalization
- analyzing contact management processes and engagement
- tracking changes over time via the timestamp fields
- integrating contact data with other systems
