IMPORT USERS AND PASSWORDS FROM SQL

How can I populate the OV internal database automatically from a SQL server? or through a csv file? This is needed to create a user everytime a guest is registered in a hotel or patient in a hospital. Thanks.

It is possible to upload a csv/xls/xlsx to OV to populate the database for guests or employees.
To automate this, it would be possible to implement an API that is doing this automated. OV has a Rest-API that would make this possible.
