FDX XML Server is another XML Server available in market. This product is created by Snapbridge. This server is also used to create and deploy sophisticated XML applications. XSL, XSLT and scripts are supported in this server so that data can be transformed to any format requested by user or any other application.

Sonic XML Server is another product from Sonic software which is built upon native XML processing engine. This helps in pipelined processing of XML documents which eliminates need for generating intermediate xml text file for processing. This improves speed of transaction dramatically.

This pipelined processing of document helps in very large and complex processing tasks to improve speed of those tasks. The in-built engine in Sonic XML Server enables a user to store any size of XML document in it and to query, retrieve and update that data.

We have seen that an XML Server is any server that gives an XML document as an output so that other applications can use it for processing. The document can be delivered in any format using XSL and XSLT engines. It is possible for us to write some code in ASP which will serve an XML document to user when they view that ASP page. We can store this code in a web server and this code can be said to be a very simple XML Server since it serves user with an XML document. Go through code given below:

<% response.ContentType="text/xml" response.Write("") response.Write("") response.Write("") response.Write("Its You") response.Write("The book outlines steps involved in developing an XML Web Server") response.Write("") %>

Save above code in your web server as book.asp and store it in same directory where you stored your other web pages. Then view that page in browser to see an XML document in display. In above code you may note that content type for page is set to “text/xml”. This is why output is displayed as XML file. You may develop a little more complex program to retrieve data from a database and generate an XML document from data retrieved from database. Thus you can start developing your own XML web server.

Weather Another feature that is becoming increasingly available is weather for a location. The system will tell you weather at a certain location on map i.e. at that beach location you are planning to visit.

When you want to plan a journey you will need to enter start and end destination, this can be done in a number of ways, city, street and house number. The street intersections, post codes and a location chosen on on screen map. The start can be done in same way with addition of present location as starting point (remember unit knows where you are). There are then itinerary or way points, these allow you to program destinations along way. Finally you are usually presented with choices of routes with choices like, Fastest Route, Shortest Route, Scenic Route, Avoid Motorways etc some have choice to avoid toll charges.

Fitting The units can be fitted into car in a number of ways but 2 most popular ways are with a mounting bracket that has a strong suction cup that sticks to windscreen. The second way is a bracket that fixed to cars air vents, this method can be very good but required a fixing for each type of car. The unit is then fitted to brackets and adjusted to best viewing angle.

There are dozens of systems available now with a variety of choices of options available. You need to choose which of above options are important to you and then choose until that best suits you or suits you price range.

You can see a large variety of different units at different costs at my favourite comparason site www.wangled.co.uk just type in "Mobile GPS"
