Technologies and Tools

PowerBuilder is our preferred tool for advanced business applications with a rich GUI interfacing to a database, often in an n-tier architecture with a data service layer as the middle tier. PowerBuilder is a 4GL (4.Generation Language) environment for making Rapid Application Development (RAD). For experienced PowerBuilder developers, PowerBuilder is certainly a real RAD tool, and PowerBuilder is naturally object-oriented as most modern tools are. The PowerBuilder Foundation Class (PFC) library is generally used to jump-start the system development, and we are using the PFC with our own extension library for in-house projects.

.NET is the technology we use for making Windows or Web-based systems for customers whose IT is based on Microsoft products. We focus on using the language C# for .NET projects, to have a leading edge language with all the advantages and less flaws than other 3GLs like C++ and Java. A Microsoft Web-based system is centered on the IIS web-server, using ASP.NET technology for the web-server applications. A .NET Web-Service application is also built on the IIS platform.
