Hi All, I have an application running in a hospital environment for a number of years. In the light of the increasing awareness of data security, the client’s IT in their own words are looking at "redoing the whole 4dcis database onto 2 or 3 tier system where there is a database separation from application layer”
The current setup is a v15 client-server application, with about 80 concurrent client licenses serving users located at 2 separate locations. As it stands, a 4D application already has a 2-layer architecture being a client-server application. We could perhaps enhance it a little to make it a 2-tier environment by moving the segregating the 4D Server software and the 4D structure files (business logic) on to one server and the 4D data files (database) on to a separate server. Doing that however has no effect on the 4D database architecture, it still remains a 2-layer database architecture. Apart from re-developing the application into a complete web-based application, how can a 4D application be refreshed into a 3-tier system? I would like to tap on the collective wisdom of the forum to gather some views on the plausibility of the above. Thank you.
