Tutorial 2: Data filtering and calculation using tags¶
The Data Catalog allows the flexible management of master data through the creation of measurement models and tag management of measurement, which can help companies obtain data flexibly and efficiently, as well as perform further data processing and storage.
Scenario Descriptions¶
In the buildings and architecture field, relevant indicators for certain buildings, floors, or equipment. A more flexible method of master data management is required at such times so that the you can more efficiently select data to be calculated. This tutorial uses the calculation of relevant indicators in the buildings and architecture business as an example to introduces using measurement models to manage master data and follow-up calculations in the Data Catalog. In this tutorial you will:
- Create a measurement model in the building business using data sync
- Create tag groups and tag, and configure tags with business meanings for the measurement model
- In stream data processing, realize synchronous data format conversion and perform data filtering and calculation based on tags
Prerequisites¶
- You have already applied for Read And Write Resources and Sync Resources on the Data Catalog’s Resource Management page
- Permission to use the Data Catalog module is enabled
- You have applied for the standalone mode container resource of the stream data processing module on the Resource Management page
- Permission to use the Stream Data Processing module has been enabled
- The model and measurement points have been created in the DCM Module, and data access has been completed
