BCCR decided to upgrade the Visual Basic code using the Upgrade Wizard in Visual Basic .NET. The Wizard includes technology developed by ArtinSoft, a Costa Rican company. ArtinSoft supplied three consultants to assist 10 engineers from the bank’s staff with the upgrade. A smart client application, now implemented with Windows Forms and user controls, talks to a server that uses Serviced Components, Remoting, and Microsoft ADO.NET, which in turn executes transactions on the SQL Server 2000 database. The upgraded system has 40 total servers, all running Windows Advanced Server 2000. Five servers run SQL Server 2000, while the rest run Web servers and business logic. The business logic and database run on high-availability clustered servers. Out of the five servers running SQL Server, two (one cluster) belong to production, two (a second cluster) are located in the test center, and one is used for development. The development process proceeds in three stages: coding of improvements and updates on the development machines, evaluation in the test center, and finally deployment on the production system.
