-
- And I'd even dispute that most C/S access is not remote file access (as in
- our C/S system that talks to 3270-based applications). The TP monitor is
- used to route the data, and is aware of the type and number of servers and
- where they're running, but there's no restriction on the data (i.e. it
- needn't be SQL!).
-
- The confusion probably arises because most C/S systems are used to more
- efficiently access corporate data - but this needn't be in the form of
- direct database access. A lot of it can also be done through existing
- applications (as in our case). It just goes to show that getting consensus
- on the eternal question 'what is C/S?' is well nigh impossible,
