# SystemUserRef

Domain entity representing System user ref data within the system users area of the claims/policy domain, mapped for NHibernate persistence.*

## Purpose
- Models system user ref data used by the system users area of this library.*
- Inherits shared identity/lifecycle behavior from `EntityBase`.

## Context
- Namespace: `SAIF.Data.Model.SystemUsers`
- Assembly/package: `SAIF.Data`

| EmployeeId | `string EmployeeId { get; set; }` | Foreign-key identifier referencing the related employee record.* |
| LastExtractDate | `DateTime? LastExtractDate { get; set; }` | Date/time value for last extract date.* |
| HasPolicyCenterAccess | `bool HasPolicyCenterAccess { get; set; }` | Indicates whether policy center access.* |

## Behavioral notes
- Properties are typically declared `virtual` to support NHibernate lazy-loading proxies (see the corresponding mapping file under `Data/SAIF.Data.NHibernate`).*

## Constraints and usage notes
- No additional usage constraints beyond standard NHibernate entity/DTO conventions could be confirmed from static analysis.**

> **Note:** Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts. Statements marked with ** could not be confirmed; treat as unknown until verified.
