Yes, that is no problem. In the HubEngine, adapters are available for all the common databases. The common databases include in particular MySQL, MariaDB, PostgreSQL, Microsoft SQL and mongoDB. All available plans can be found via the following link:
If there is no adapter for the database you are looking for in the list, we can develop a suitable one on request. The effort for this is not particularly high (special HubEngine framework).
The synchronisation schedules can be set up flexibly between the database and Leadtributor via the appropriate HubEngine adapter (cf. screenshot).
