What is your question? Are you asking for the Lazarus equivalent of
Datasnap in Delphi?

AFAIK there isn't one. You have to write the middleware layer
yourself. I wrote a simple one using Indy10. Since Delphi 2009,
DataSnap has been based on Indy anyway. 

Check out the following

Freeware alternative to MIDAS in Delphi

I've never tried it in Lazarus but the source code is available so you
can try to port it

N-tier multiuser application development

How can i develop Lazarus multi-tier applications(like delphi
midas!!!??)?

You can also try tiOPF

I don't use it but they say it's good.

Actually I'm just asking, I'm not planning to use DataSnap even in
Delphi, and even once.
Why NOT?
There are lots of database server like:
mySQL,
Firebird,
msSQL,
Oracle
etc.,

So, why bother using that, while we can make fast, using those servers
3tier?
1. Application Development
Using Lazarus Free Pascal  Language
2. Database Server
mySQL (linux/windows)
Lazarus Free Pascal Win Forms with mySQL Server (linux/windows)
3. Clients
Lazarus Free Pascal Win Forms with mySQL connection (linux/windows)


thanks

btw, I've read your post before asking this

kbmmw was working on a Delphi port I believe

I haven't used it myself, but some Delphi programmers I know were
quite happy with it.
