From desktop to web [power engineering software application]

This paper presents an overview of the conversion process for a specialized software application from a desk top environment to a web based environment. The technology based business software is used in planning applications for new electric power generation and storage facilities. The software, called TAG-Supply/spl reg/, is an integrated application of database, text (pdf) and an analytical engine. The desktop version of the TAG-Supply/spl reg/ is a 32-bit client server application written in Visual C++ 4.2 making use of a proprietary object-oriented database and a pre-Windows GUI. Because of the ageing GUI, obsolescence of the database, updates to C++ since development the update to the application software was necessary. After evaluating the options, it was decided to make the move to a web based application to include a database for multiple user access, saving and retrieving. The technology for the new architecture is ASP, SQL Server 2000, Windows 2000 Server and IIS 5.0.
