Data Flow Manager - Version 2.0 Data Flow Manager (DFM) is an add-in for MS Accessr, designed to easily plug into your custom MS Accessr database application and efficiently manage the flow of data in and out of the application. Almost every MS Accessr based desktop application that you develop has a requirement to communicate with other systems, big and small. Systems communicate through a cyclic process of data transfers. Yet, there is no tool available today that helps you do this in an efficient and elegant way, without having to build your own interface framework every time. Well... not until now.
