Maria db y camunda modeler

Hi, I need your help, I have a project from eclipse and camunda, both are connected and the result is correctly reflected in tasklist but i need to connect the project with MariaDB, i had created a database and one class from ecipse which makes the connection with MariaDb and I can query data, but my question is how to do so that camunda modeler can store the data in MariaDb
because as I have it, the class is to query external data but I cannot connect it directly with Camunda Modeler
I need the tasklist to see the queries I made from MariaDB
