Soren - short answer is - I'm afraid - you get what you pay for. Equally -
and very important - this is not a MapInfo-specific issue. All the GIS
vendors - in fact all the vendors full stop- have the same issue when sharing
data between desktops

Subject: SV: MI-L MapInfo files on server
Hi,
Thanks for the shocking answers; I thought it would be easy to set up
a
server application :( It looks like I have to keep the files on
local
machines after all and still use Uffe Kousgaard suggestion.
>If you have 10 users, that update various parts of a database, then
have a
field called userid and give it a value from 1-10, depending on who
modifies
that part of the network. When you get the updates back from user 7,
delete
all records where userid=7 and then append the records from user 7,
where
userid=7. This even allows you to give the users a larger part of the
database, than just the part they are going to update.<
Why has MapInfo not developed an easy server solution??!!
Regards
Soren

Ãmne: Re: MI-L MapInfo files on server
Hi all,
I'll add yet another concern to have in consideration: any standard
MapInfo
Pro will thrash any 3rd party setup since supporting
intelligent TAB multi-editing is not natively supported by Pro (with
proper
locks etc.).
To succeed one needs a stringent environment, in which every single
client
conforms to the multi-editing setup and abstains from
using all the standard table opening and updating methods. Including
all
tools from various sources !
Unless one has few users and dilligent IT enforcers, the setup will
break at
some point. I think this comes under what Paul calls
"Resilience".
I know that Michel talks about MapX, and here its much simpler, but
multi-editing is inherently more interesting to contemplate in a
Pro environment.
Don't know if v8 will come to provide the necessary mechanisms to
implement
record/table locking.
Best regards/Med venlig hilsen
