When importing data into the Digital Twin, you may deal with inconsistent data sources. Even when data sources contain consistent data, you may import objects you already have imported before. In order to avoid duplicate data and to clean up inconsistent data, use Data Aggregation
When aggregating data, you merge your imported data to one single data source. This single source is called the Digital Twin. Main scope of Data Aggregation is to help you solve inconsistencies in tagging and attributes, and to have consistent data in the Digital Twin.
