technology is not an alternative, because applets neither support complex
persistance, nor survive the exceptions raised on connection loss (session). Excessive loading
times occur on each re-start of an applet.
How to solve these conflicts ?

in short: The synchronization between devices and server is confronted with a
very complex scenario of items on change. Here is one of the application hearts
- we use elaborated algorithms to resolve all possible conflicts in order
to present consolidated data to the user and the server side applications. With
our applications, it is even possible to have more then one user operating on
the same data, e.g. on the same work-list. Look at this Scenario: 2 or more
devices get the same work order, because their users are working on the same
object. Their data will be combined the smart way. Ask us for details, we
can proof this!
Template driven technology
Templates define major parts of the application's
behaviour and functionality. Templates are text files in standardized XML
Where are the benefits?
The application is generated on server side using the template input and distributed to the
clients. This approach has all those advantages, which came up with the web
technologies. But it takes a step further, because we now can run the
clients even offline, while keeping the central, single point deployment and
therefore an inherent update capability for data and code.
The template finally defines, which user data fields appear with which data,
capabilities, constraints and so forth. The server processes it for the
database persistance layer and produces the user interface code and
data files, which are downloaded on demand to his clients, whenever they
