+#### 자동 생성 필드
+
+- **OID**: `@PrePersist`에서 자동 생성 (고유 식별자)
+- **생성일시**: `@CreatedDate`로 자동 설정
+- **수정일시**: `@LastModifiedDate`로 자동 갱신
+- **생성자/수정자 OID**: 사용자 추적용
+
+#### 사용 예시
+
+```java
+@Entity
+@Table(name = "st_members")
+public class Member extends BaseEntity {
+    // OID, 생성일시, 수정일시 등이 자동으로 관리됨
+    private String userId;
+    private String name;
+}
