Web Services are a standardized way of ensuring security and the ability to manage technologies by combining web based applications that are independent of a vendor. Web Services are independent of a browser or HTML. Web services allow different machines that otherwise wouldn't be able to communicate with each other the ability to do so. Web Services focus on business functions and data which is communicated using different programming languages to produce a functional application that will met the requirements of a business. The web services are then added to a GUI (graphical user interface) which can be a web page or a executable program that is presented to the user. The communication that takes place in Web Services is between different programming tools like XML (Extensible Markup Lanquage), SOAP (Simple Object Access Protocol) , WSDL (Web Services Description lanquage) and UDDI (Universal Description, Discovery and Integration).
Web services are a good way for businesses to communicate with customer's and improve information flow between both parties. Their usage has grown in the last couple of years because developers have seen the potential of web services as a tool that can improve customer and business satisfaction. Some examples of web services would be sites that provide up to the minute stock quotes and online auctioning sites such as Ebay. Ebay is using (API's) application programming interfaces to provide a way for customer's to interact directly with their databases giving to up to the minute information on the products offered and the current selling price.
According to Webopedia, there is a website called Wikimaps that's using new web services called mash-up's. A mash-up can take information from different sites such as Google maps or yahoo maps and combine it with another web application to create one web service with information from all these areas. The website for wikimaps is www.mywikimap.com
