We have developed some web portals and some web applications using service-oriented architecture.

SOAs offer the following advantages over traditional approaches to distributed computing:

• They offer business services across the platforms
• They provide location independence
• Services need not be at a particular system or particular network
• Completely loosely coupled approach
• Authentication and authorization support at every level
• The search and connectivity to other services is dynamic

Benefits from the perspective of Business Value

• Ability to more quickly meet customer demands
• Lower costs associated with the acquisition and maintenance of technology
• Management of business functionality closer to the business units
• Leverages existing investments in technology
• Reduces reliance on expensive custom development

The web services has been developed in a Web Services Contract First approach.

For the front-end we have use ASP.NET and ASP.NET AJAX to create a rich and responsive user interface.

We have use Microsoft SQL Server 2005 as a database server. This capable and at the same time affordable relational DBMS (RDBMS) provides high-level security of the data stored and high-speed access to the information.
