Tutorial 1: Creating a master data model and relationship model

The management of master data is a crucial part of enterprise data governance. The Data Catalog supports model-driven and relationship-driven master data management, as well as improving data search by establishing business terms and tags as a means to help companies gain value from massive amounts of data.

Scenario Descriptions

This tutorial, as an example, uses the management of master data related to wind turbine business in the wind power generation field to introduce operations such as synchronizing data in the Data Catalog and establishing master data models and relationship models. The detailed process is as follows:

Main process

Introduction

Subtasks

Master data type definition

  • Station data type creation

  • Monitoring application data type creation

Master data relationship type creation

Establishing a relationship model among wind turbines, stations, and monitoring applications

  • Wind turbine station relationship modeling

  • Wind turbine monitoring application relationship modeling

Data sync

Synchronizing external data sources to the Data Catalog through Open API with simultaneous data verification and alerts during the sync process

  • Open API data source registration

  • Master data sync

  • Master data relationship sync
