XML Application
Development is one of the key technologies
that are driving Enterprise development
today XML Application Development promises a
standard data format that can be shared
easily across applications and different
organizations that need to share data.
|
XML is a key
technology in distributed applications. But
unlike other over-hyped technologies XML has
been rapidly accepted because it solves very
specific technical problems by using a
standard protocol/data representation. The
simple act of agreeing to a common data
format for data is making data exchange
drastically easier than it ever was before.
|
Even in its
simplest form XML as a standard has lots of
potential as a data representation and
messaging mechanism. Data representation
typically involves translating the data from
a native format into XML, and then back into
the same format or even a completely
different one on the other end of a
connection.

has the experience & the technological
expertise the highest end solution in XML
domain. We have experience in designing and
developing application which require strong
knowledge of XML, Schema, DTD & XSL.
Following are some of the examples that
drive the acceptance of XML:

XML as
a standard data exchange format
This is particularly useful in Web
applications where XML can provide a
standard, agreed upon format to transfer
data over the Internet. In this respect XML
is similar to a data format such as Comma
Delimited or SDF file in the past. However,
as a data representation format XML is also
much more powerful & flexible than these old
formats. Most other text formats have been
hampered by their limited ability to
transport complex data like memo fields or
binary data. XML is very flexible in what
kind data it can carry because of its tag
based language definition where every XML
data element is marked with a start and end
tag.
|
A good example
may be a VB.net application publishing some
of its data via XML and another application,
possibly a Java Servlet, picking up that XML
data and using it internally.

Support
for multiple sub-documents
Another huge advantage of XML as a data
representation mechanism is that XML can
combine multiple pieces of data into a
single document. The markup language has
support for stacked and hierarchical data
representation. XML documents can combine
several separate entities (be it tables,
objects, messages or metadata) into a single
XML document. For example, you can send the
actual data of say a table, as well as a
message header that describes the data or
maybe contains any error conditions that
might have occurred in obtaining that data.
You could also combine multiple tables (as
an example) into a single document. Or a
table and an object both parsed into XML.
