Unidata does indeed support triggers. You can define update and delete routines that are run automatically by the database itself. The trigger would provide you with an API to add additional processing whenever the trigger enabled file is written to. That API hook is a UniBasic routine that has access to the data about to be written and provides you with the opportunity to add any logic you like to it. That could be running another application, writing the data to another file, creating an XML file, running a webservice, etc., etc. whatever the system is capable of.

Is this what we're talking about? It sounds like you're talking about database triggers. I don't know off-hand if Unidata supports triggers but if it does then the answer is yes. (I can ask on my side and get an answer on that but I'm sure someone will chime in here.) One of your normal processes will update a unidata file, the trigger sends an event to some remote process which then puts the data into some other application. The "other application" must have an Application Program Interface (API) which is a "plug" that we can hook into for importing and exporting data. I personally specialize in understanding these plugs, and connecting products like this with MV apps. This same sort of thing can be done by storing data to a localhost OS file and then spawning another program to process that data, but this may not be possible if your "other application" isn't on the localhost. Part of the service we provide is getting to understand your topology so that we can recommend effective ways to do these things. If mv.NET isn't the right tool for the job, like if you need a completely Linux solution, I won't try to sell mv.NET.
