Quick Start: Create Measurements and Associate Assets


The Data Catalog allows users to create and import multiple types of metadata and master data, as well as to tag these data objects, associate business terms, and establish relationships between data objects. These features exist to help companies manage, discover, and govern data, as well as accelerate the digital transformation their enterprise.

This article, using the creation of a measurement (Measurement metadata) object as an example, and using the primary user path instance of the Data Catalog, helps users quickly get started with core functions such as tagging data and associating business data.

Step 1: Create a Measurement

Measurements can be created in two ways:

Create Manually


  1. Log in to the EnOS Management Console and select Data Catalog from the left navigation bar.

  2. Under the left side of the Data Asset Explorer page, find the Quick Guide, and then click Create Measurement.

  2. On the left side of the Data Asset Explorer homepage, under the Metadata Object Statistics header, click the blue number in brackets in the Measurement category to go to the main page of Data Asset Explorer.

  3. In the search box on the upper left, enter active_energy_reading and click the Search icon search_object_icon to retrieve the newly created measurement data.

The series of operations described above enable measurement data to be better managed and understood. Users can refer to these operations to create other types of data, and associate tags/terms/assets, to more clearly organize large amounts of enterprise data.
