A mysql database is currently used to provide the data of events. The db config setting is stored in echo_api/inc/dbcfg.inc.php.
You will need at least a table "ed-event" for storing events, with the following fields:
Event id. This is the primary key and is auto-increment.
User id. You can establish user managment with a second table "ed-user" which identifies users with a unique user id.
Start time of event. datetime format.
End time of event. datetime format.
Datetime or timestamp format for storing event updating time.
