Web Services on Rails

Mon, 12 Feb 2007 11:00:00 EST

The term Web Services refers to loosely coupled, executable application components linked dynamically over the network with open standards. Typically, they are software components that employ one or a combination of the following XML standards: SOAP, WSDL, and UDDI. Ruby on Rails is an open source Web application framework written in Ruby that closely follows the Model View Controller (MVC) architecture. It strives for simplicity, allowing real-world applications to be developed in less code than other frameworks and with a minimum of configuration. To define Rails - the Web Services or a Web Framework - we have to say that Rails is a full-stack, open source Web development framework that requires comparatively less time and effort to code XML interfaces than most other frameworks.

Adding Reliability to Occasionally Connected Computing in Mobile Devices

Mon, 17 Apr 2006 15:30:00 EDT

Mobile devices use wireless networks that have limited range. Therefore, they may not always be connected to a network. This kind of intermittent connectivity in mobile devices has been one of the factors inhibiting enterprise-level adoption of pervasive mobile applications. Occasionally Connected Computing (OCC) deals with this problem. The challenge that mobile application developers face today is to develop applications that will let users interact uniformly with the application regardless of the connection status.

Legacy systems are a core asset at many organizations. These legacy systems have been around for decades and have a very critical impact on day to day business processes. However, owing to a variety of reasons, these legacy systems have high TCO and represent a bottleneck towards the emergence of an agile IT portfolio. In this article we'll focus on a variety of options that may be available for the seamless integration of legacy systems with an enterprise IT portfolio.

Differential QoS Support in Web Services Management

Tue, 13 Sep 2005 09:00:00 EDT

Web services are gaining acceptance as the prime technology used to interconnect disparate applications and ease interoperability between heterogeneous and autonomous systems both for internal and external integration. The variation of contexts in which shared Web services could be used and the resulting variation in functional and Quality of Service (QoS) requirements motivate extending Web services management platforms with more sophisticated control mechanisms to cater to differentiated service offerings.
