Abstract: Techniques for communicating between an embedded device and at least one remote database for a wide variety of applications, including human machine interface and supervisory control and data acquisition and B2B applications. An application program interface interfaces an application program seeking access to a predetermined database and which operates on an operating system not operating a database driver program. A parser translates communications with the application program interface into and from commands and formatted data of an operating system independent form. A protocol stack formats the commands and formatted data into header formatted communications signals to accord with a predetermined protocol. Another protocol stack receives the header formatted communications signals and removes header data from the header formatted communications signals for generating database communications signals.
