Fivetran is a data integration tool that automates the extraction and loading of data from various sources to a data warehouse. In collaboration with Google and Looker, Fivetran has introduced analytics templates for NetSuite, an essential yet complex ERP system. These templates aim to simplify data integration and analysis by providing a foundation for creating specific dashboards and reports. To use the NetSuite template, users need to set up Fivetran, connect their Netsuite data, access the Github repo, implement Looker source block, and start visualizing and analyzing their data.
