21 Department API

This chapter provides a use case for the Department API that describes how to create, update, query, and delete departments in Oracle Enterprise Repository.

This chapter includes the following sections:

21.1 Overview

Departments can be created, read, queried for, and modified. These operations are described below. Bear in mind that after a Department is created, it cannot be deleted. Only two Department attributes are meaningful to a user: name and description.

Additional Import(s) Required

import com.flashline.registry.openapi.entity.Department;
