Web applications are browser delivered programs popular in modern computing for their ease of deployment and rapid development. The benefits of such systems are that they can be extremely cost effective but still retain the functionality that traditional thick clients offer.
Working on a Client Server model, the computing is done at a central server whilst the application is rendered at the browser (client). Because of this scalability is dramatically improved as well as maintainability.
Here at SIS we primarily develop with Microsoft's proprietary ASP.NET framework which allows us to leverage a vast amount of existing code. This means we don't have to reinvent the wheel. Also the use of ASP.NET lends itself to work with Microsoft's enterprise level RDBMS SQL Server seamlessly. By using these two technologies incredibly robust applications can be created offering excellent performance at very little cost.
We are however not tied into any technology and have the skills to adapt to any given project if we can see advantages in doing so (e.g. Java, Perl or PHP).
