Data Collection Systems

1. Sources of data, for example telemetry. Typically the source or sources are interfaced to the VME bus.

2. A repository for the data. This can be a raw device such as a tape, or it can be a disk file or even a database system.

3. Rules for processing. The data collection system might be asked only to buffer the data and copy it to disk. Or it might be expected to compress the data, smooth it, sample it, or filter it for noise.

4. Optionally, a display. The data collection system may be required to display the status of the system or to display a summary or sample of the data. The display is typically not required to maintain a particular frame rate, however.
