True ETL Tools
If you need more than just to copy data from Help Scout to MariaDB, you may use Skyvia's powerful ETL functionality for Help Scout and MariaDB integration. Skyvia's Import tool will correctly extract Help Scout data, transform it, and load to MariaDB when MariaDB tables have different structure than Help Scout objects. Moreover, Skyvia Import allows loading data in any direction, supporting Reverse ETL scenario.
For more complex cases, you can use Data Flow and Control Flow tools. They are designer-based solutions for creating complex data pipelines, involving not only Help Scout and MariaDB connectors, but any number of connectors in one integration. With these tools you can automate data workflows, involving custom logic, complex multistage transformations, combine data from different sources, load them into multiple destinations at once and many more.
