I am interested in setting up a multi-user database using an IBM compatible
system.  I would like to use DOS but I am open to using another operating
system (I do want to keep my cost down).  The type of system I expect to
develop serves users with database features, providing them access to a 
database which I will maintain.  I would like to begin with three multiple
users then grow from there (with at least a potential of ten users using 
the database at the same time).  The users will access this BBS system through 
regular phone lines.  Any information about setting up a system like this
would be helpful.  I have just started developing this BBS system
and need to know things like:  what BBS software could I use, what database
software can support multiple users and still look great over a BBS network,
how much processing power will I need to support these users (How do I 
determine this?), how would I connect more than one PC to access the common
database to support more users, is there one modem on the market that supports
multiple phone lines, is there a number to a tech. application engineer which
I can talk to about this application, etc.

I don't think this is a trival task and have posted this message before; however
as of yet, have not gotten any response.  I don't know if others do not 
understand this question or if no one has this experience.  Please if you
have experience with setting up multi-node networks, and do not understand 
this question please send me a message indicating this, so that I can
clarify myself.  Your help is needed.

                               
Thank you,
