>>The accountant (= accountant(s) + employees) decides to work on my data today (customer 27, year 2008). If (say) 00027_2008.mdf is not attached, it has to be attached to the sql server instance so he can work on it.
>>
>>If another employer wants to work on my data at the same time, the 00027_2008.mdf does not have to be attached since it already is. So he can simply connect to it.
>>
>>When the last person is done with 00027_2008.mdf, it has to be detached from the sql server instance [ we are talking about thousands of databases ]

A web app - horror

I've seen one - it's not practical - response time is important - very important
