The CMS Barrel Muon Alignment System is composed of a series of elements - each of large quantity -to be calibrated individually and together after assembly. This requires an approach based on modular control and data acquisition HW/SW including data validation features during data taking. The measured data of all calibration steps (including full images) are stored in a database together with the final results obtained after the processing and evaluation of raw data. A dynamic

WEB-based reporting tool makes it possible to follow the status of calibration and assembly, and to search for any data.
