With this bundle, you get an additional custom report of type "External database" in the Pimcore backend on the "Custom reports" page. With the help of the bundle, you can on the one hand access external databases (e.g. the database of your ERP system, your online store), and on the other hand, the bundle fixes a vulnerability of the standard SQL report adapter of Pimcore by also being able to execute complex statements to query the Pimcore database (e.g. UNION statements). Additionally, in combination with the Pimcore Data Director, you can not only display data from external databases, but also import them into Pimcore right away.
