UNIQO HMI supports data storage both on relational databases through ODBC connectors, and on embedded databases, which also offer all the necessary reliability features. Embedded databases are easy to use and occupy limited resources, making them an ideal solution for applications on entry-level HMI panels.

An efficient mechanism has been introduced to back up embedded databases and restore them during project execution. Through hot backup, the data can then be stored in a different location from the device on the field.
