The CData Sync Application is a tool that allows users to replicate their NetSuite data for use in third-party BI tools like Tableau. By replicating data from over 60 on-premises and cloud-based sources, including QuickBooks, Salesforce.com, and SQL Server, the application provides users with easy-to-use solutions for synchronizing data to various databases. The process involves configuring connections to both the data source and replication database, selecting tables to replicate, and setting a replication interval. The Sync Application performs incremental updates, providing fast and frequent data refreshes. Users have flexible configuration options, including the ability to perform operations on the data before replication, as well as scheduling replication at desired intervals. With its secure and monitored backup capabilities, the application offers stand-alone installation without online hosting or transactional fees. By replicating NetSuite data, users can leverage the power of BI tools like Tableau for advanced data analysis and visualization.
