After you have logged in to your portal you might have noticed that there are some numbers at the end of every page.

 

 

Believe it or not, all those numbers have a meaning:
V: x.yy is the version number of the frontware (Web interface)
MW: aaa.b.ccccc is the version number of the connected middleware
DM: dddd.e.f is the versionnumber of the datamodel from the database.

 

Last but not least there is also a non visible number of the system services being used. The last part (IP/CTY) is your IP address resolved to a certain country/region.
