Volia Software addressed Softengi with a request to perform works for one of its customers – RISC, Inc.

The company had the already developed system called Virtual Training Assistant (VTA) – a comprehensive application automating the process of personnel training for large corporate customers in the United States.

Softengi’s main task was to port the system, which was initially developed with Microsoft Visual FoxPro, to Microsoft .NET platform considering the predetermined extensibility requirements. Besides, it was necessary to extend the system with the new functionality at the succeeding stages of its development.

Challenges

The ultimate goal of porting the system to .NET platform was to employ new facilities provided by this technology, create thin web clients as application front-ends, extend security mechanisms, provide multilingual UI, increase performance, etc.

Another challenge was to provide better supportability, since Microsoft announced that it would stop supporting VFP 9 soon.

Besides, special synchronization strategy was needed to ensure subtle migration process for the current users of the running system.

Softengi Team Tech Contribution

Softengi team has split the porting process into several stages focusing on certain subsystems in the application suite.

It used the agile development methodology, as well as the most essential practices like model-driven engineering, prototyping and test-driven development.

In the course of the system extensions development Softengi provided support and kept close communication and collaboration with the customer with regard to both on-site and off-site activities.

Main contributions made by the Softengi team:

  • Changes made to certain elements like security, multilingual, license management, and others.
  • New system architecture meeting such specific requirements as possibility to work in distributed environment, integration with legacy system, etc.
  • Functional changes and changes in interaction scenarios to achieve balance between expectations of users used to work with VFP-based system and new possibilities provided by the modern technology.
  • Scalable solution targeted to various categories of users from small companies to large corporations working under two pricing models – ASP and Licensed Software.
