 ## Where to store data
 
 Most of the data are stored in a database and can be stored outside the Bonita container as described above using the PostgreSQL or MySQL container. However, some data remains inside the Bonita bundle. Bonita Home is a folder, called `bonita`, which contains configuration, working, and temporary folders and files. There are also log files inside the `logs` folder.
