Setting up EnOS Common Data Service¶

This page describes how to set up EnOS Common Data Service for the first time.

Prerequisites¶

Common Data Service needs to be obtained, authorized, and enabled in the current OU and the target asset tree needs to be tagged with EnosCDS:true.
Common Data Service needs to be authorized to perform the following operations through APIs in the current OU:
- Obtain the ID, username, email, and phone number of all users in the OU.
- Obtain all user permissions in the OU.
For more information about how to assign API permissions, see Authorizing API Permissions.
You need to be assigned the required asset permission and operation permission, and a menu group containing all menus of Common Data Service. If not assigned, contact the application administrator.

Workflow¶

The workflow to set up Common Data Service is as below.

Decide if the existing datasets can meet your needs:
- If so, get the data through Common Data Service APIs.
- If not, go to the next step. This page assumes that the existing datasets cannot meet the needs.
Decide if configuring virtual data based on the existing data can meet your needs:
- If so, configure virtual data and get the data through Common Data Service APIs.
- If not, go to the next step. This page assumes that configuring virtual data based on the existing data cannot meet the needs.
Prepare the required data sets and standardize the data source API according to specifications, and then register the data source API in Common Data Service.
After the data source is registered, register the meta data in Common Data Service to declare the data content that the data source can provide.
After the meta data is registered, query data using Common Data Service APIs to verify data configurations.
