Hmmmmm. Interesting comments about the threading. We stayed away from
doing any cause we had enough problems with business rules.
MTS negates any threading issue that I can see .. so far.

>We have all our SQL externalized. Fully user configurable and designable

>We are considering Ports to IBX, and Oracle DOA, Dont think this will be

>much problem. We make extensive use of caching both at the AppServer and
>the
>Client side. As you can see I really enjoy MIDAS. The down sides are you
>need to design, it is inefficient project management for a small team, it
>is
>hard to stream and manage your own objects, and debugging client and server
>simultaneously can be a drag.

>Overall the Sanderson Client is a success, and will go Global early next
>year.
>
>Some other comments...
>
>Once the team gets over three people you start to pick up development
>efficiency gains because you can modularise a lot more, and give your team
>members seperate projects to work on.
>
>I cant stress enough the importance of an initial R&D phase where you
>design
>your Server Threading strategy very carefully. We use multiple RDM's for
>logical business partitioning, and each RDM inherits from a base RDM
>
>Midas bigest enimy is its lack of documentation..
>
>RDM inheritance is important to understand.
>
>Traffic considerations are important...ALWAYS use small datasets...
>
>Sync is a real issue to contend with
>
>Feel free to pass anything on you like. Overall, we really like MIDAS. I
>see
>MIDAS as a strategy - as much as a technology.

>If you go with the flow it is quite easy, and good. Just like BDE and other
>strategies, if you go with it it works for you. Fight it and you'l hate it.

>guesse thats my bigest advice to anyone.
