Creating applications with DataFlex

To create applications with DataFlex, there are three products to your disposal. The most important one is DataFlex Studio. In Studio you create tables, business rules and applications. For integrating reports in your application you can use DataFlex Reports. To add management information to your applications, take a look at Dynamic AI.

For deploying DataFlex applications

Depending on which platform you seek to deploy, you will need special components to do so. For running on Windows, you will need Windows Client licenses and for a web application, you need a WebApp server. Depending on which database system you want your application to run on, you will need a Connectivity Kit. If you will be using the free, embedded DataFlex database, you will not need a Connectivity Kit.
