Help!Database , DCOM Database over network .

Hi,I have to create an application with a central database stored on a network server and applications using this database in a variety of departments.
The maximum amount of users at any given time would not be greater then 150 and probably on average around 60. I want to use DCOM technology to access to the Database because i don't want to install Oracle client on client machine.(must be certification for number of the Oracle client).If is there restriction of the Oracle server for entries Dcom clients?

If is there better TECHNOLOGY for access network database.For examle client/server?

I'll very glad to any answer.Thank you.
