Hi group

Well, today I went to this hands-on seminar, and I'm impressed.

The core of the engine is an object oriented data store. You create as
easy as in Access - in a very nice designer using a basic like
language - classes for storing data. When compiled, these classes are
at once compiled too - and represented - as tables via ODBC and JDBC,
classes via C++, Java, ActiveX (COM), .net and XML, and you can access
the data simultaneous via all interfaces. These layers are all highly
efficient they claim is the main reason for the high speed of the
engine next to the speed of the engine itself.

Further, you can create CSP pages similar to ASP and JSP pages with a
direct connection to the engine. An add-in for Dreamweaver is offered
with wizards for creating web pages. These pages are interesting as
they offer live update of presented data via either a server call or a
hidden frame meaning that requery or repaint of the displayed page is
avoided - this is in my opinion mandatory for anything serious
application-like running in a browser.

The best perspective of this, in my eyes, is that you can start using
the engine and your proven tools whatever they might be (Access) while
moving to or adding other interfaces like another language, a browser
interface, XML or web services (SOAP). Rome was not built in one day,
remember.

The engine scales to shadowed servers, clusters and TB size with no
more efforts than within reach of a developer (we are impatient and
really have no time for this, you know), and it runs on close to
anything including WinNT/200x/XP, Redhat/Suse Linux, Solaris, OpenVMS,
Tru64, HP-UX, AIX, and Win ME/98 - even Win95 - and MacOX with the
next release - requiring modest hardware only.
