Best way to pass data to a WebService

[Anil Pundhir]

What is the best way to pass data to a web service.
The client(to send data) has .net environment and also the server on which
the web service is hosted also has the .net environment.

Should I send dataset or an xml which will be created at the client and
parsed at the server, in the web service.

Which will have a better performance.

Thanks,
Anil

for the best performance, use with services with TCP, see wise, and if
possible do compression for the data. bear i n mind is not the best for
interoperabilit y. avoid dataset i possible

If you are using XML on the wire, the choice of data set or custom classes
will not be significantly different. My own preference is to create a
strongly typed, class based interface that is comprised of data types that
readily map between Java, XML Schema data types, and .NET framework. In
general this means stick to string, float, double, int (not integer), and
dateTime. Avoid fancy schema constructs such as group or union - as these
map poorly to object based data representations . Feel free to use
inheritence, but avoid secondary interfaces on your data objects.

The advantage of this approach is that it is more closely mapped to the
application domain, and it avoids the loosely coupled interface that things
like passing strings (which contain XML), XMLDocument/XmlNode etc, or
Object. This aids in reducing the need to help the client side developer
understand what data will be sent/passed and for how long (e.g. contract
stability).

Additionally, avoiding loosely coupled approaches and/or single platform
data types (such as Java HashMaps and .NET datasets) helps you achive the
primary benefit of web services - cross platform interop.

I hope this helps
