Yes, the BaseHead Server is just a small program that runs on your server that shares centralized databases to the BaseHead clients.

It all depends whether in your facility if you have one person in charge of adding files to the database and editing descriptions or allowing multiple people to do this,
If everyone is allowed then the server is needed or if only some people are then you might also want it to set permissions to lock out certain functions from interns so they don’t do much damage…8)
If only one person is allowed to add and edit then the answer is NO you don’t really need it.

We suggest getting 20-30% more connections then you have BaseHead clients.
Connection are not the same as clients.  Each client needs one connection to hold the database constantly and if a user is adding files to the database or renaming descriptions and searching all at once from one client then more then one connection is being used from this client.
Think of a connection as a single operation being done.
Also, if the administrator is logged onto the server making changes this also uses a connection.
So if you have 10 users in your facility we’d recommend getting the next level of 20 connection.
If you have 7 clients  then you should be fine with 10 connections.

the Ultra Edition is server enabled built in, BUT new in version 5.x is the ability to purchase a server Add-on so it can be used with 5.x Lite and 5.x Standard also now.

Nope, it’s a tiny program that just hosts the database .db files and returns search results.  It’s not streaming audio or anything like that.  Basically, it receives searches in and spits results back out to the clients is all it’s doing.  It’s not processor intensive, but of course the faster machine the better always….;-)
