Accessing data during acquisition.

[mf@lfb]

Hello, my application acquires 16 analog channels, 30 scans/s and continuously dumps the values to a file. A second application should communicate with a database over a serial port and send 1-minute mean values of each channel once every minute using a protocol tbd. Are there any issues accessing a file for read while it is opened for write by another task or could the requested functionality also be implemented with LabView?

Using the intermediate and/or advanced file IO VIs you should be able to read and write to a file that is open. You can also just communicate with the database directly using your LabVIEW application. The VISA VIs make serial communication, or communication over many other ports, very easy. I don't see any reason why you need a separate applicaiton to communicate with the database unless you want it that way.
