Zen is an InterSystems Web application framework. Using Zen you can easily and rapidly build data-driven web applications with rich and highly interactive user interfaces. Zen includes an extensive library of data aware user interface components. These components come ready-to-use, but they can also be customized, combined, and extended to create new components. Zen components are also tightly integrated with the Caché database making data exchange between Zen components and Caché fast and efficient as well as easy to develop.
After running PROTOCLASS on your DICT files, you can use Zen with your multivalue data. You can also use MVBasic to code your Zen methods.
Caché provides extensive documentation for Zen. See both Using Zen and the Zen QuickStart Tutorial.
