You Have Enjoyed the Benefits of MultiValue for Decades but Now...

Client Demands for Web and Mobile

Many applications still rely on 'green screen' technology in spite of broad demand for web and mobile interfaces. Extending MV apps with these capabilities are critical.

Inability to Leverage Modern Technologies

Once there were a dozen providers of MV databases competing and innovating. In this shrinking market those investments have also shrunk.

With many experienced MV developers retiring and little to no new developers entering this industry, the risks of maintaining your applications have increased.

To the contrary, investments of hundreds of billions of dollars in modern database and development tools are left untapped by many MV applications. 

You Must Modernize, but the Choices Are Daunting...


Decades of business logic. The thought of unwinding, coupled with the impact on business processes seems impossible to reconcile.

Buy New?

The cost, time and risk of finding and implementing a new system seems equally intimidating.


Building new apps that leverage your MV applications and surfacing data in ways where modern reporting tools can be the answer.
