hi all,

i am using D7+mySQL 5 to develop my inhouse ERP solution, trying of migrate
my application from C/S
to multi-tier, my question is, did i need to use RemObject Data Abstract or
using the exisitng
delphi7 MIDAS component? What type of connection did i need to use? My ERP
con-current users can
be up to 100 users. Any suggestion is appreciated. Thanks.

There are several multitier framework you can use, including RO-DA, Others
are MIDAS, kbmMW, ICS, ... and RtcSDK. I, myself, working on our ERP system
using RtcSDK, combined with embedded Python used as business process
execution language. Having dynamic language such as python being used as
business process language is a lot of fun, flexible, allow dynamically
changed without need to recompile the whole server.

Thank Jaimy,

I read on the RtcSDK website, seems that the application server is using
the HTTP server, some kind of socket connection, am i rite?
Will it be able to handle a huge connections? Or possible to peform load
balancing if more then one application server deployed.
Thanks in advance.

Basically, larger request could be handled because it use stateless
connection, but of course there will be a limit in which could only be
solved by implementing load balancing. This feature is unavailable on
current RtcSDK, if you want a middleware framework that has load balancing
feature, may be you could give a try kbmMW.

How about the RemObjects? Do you try it before?

I use RO SDK and recommend it. The nice thing is that you can use it as
the communication layer for DataSnap. This way you can still use
standard DataSetProviders and ClientDataSets. It also supports load
balancing and the like.

RO DataAbstract is another product and will replace DataSnap
completely. It's a good tool if you need to support several databases
and plataforms (Win32, .NET, Linux, MacOS).
