Hi, Roshan
In top of my head, There is a two or three major part on Re-engineering
1. Data Base Server
2. Presntation Server
3. Business Logic Server
1. SQL base data base are recomended
like Oracle, SQL server...
2. Web Sever is recomended
IIS base ASP, ASP.NET
http://www.port80software.com/surveys/top1000webservers/
3. Web services to connect other computer
like business logic processor, any computer as long as
Web services is available even if legacy computer.
Please download a sample from www.exmlsoft.com
Oracle to ASP, Access to .NET, etc...
