CData Sync is a software tool that enables users to replicate their NetSuite data to various databases, including on-premises and cloud-based options, to facilitate operational reporting in BI tools like Tableau. The process involves configuring connections to the NetSuite data source and replication database, selecting tables to replicate, and setting up flexible scheduling and incremental updates. With CData Sync, users can create custom queries to replicate specific data and perform operations on it before replication, and access secure, monitored backup and archiving features. By replicating their NetSuite data, users can leverage the full capabilities of Tableau for data visualization and analysis, while staying up-to-date with the latest changes in their data source.
