Christie's are the world's leading art business with global auctions and private sales that totaled £3.3 billion in 2010. Using an adapted version of 4D-powered Matrix CMS by the UK's Matrix Software, users can log into the content management system via a browser from any of Christie's 57 offices. The system has proved to be a great success, trimming several days off of sale catalogue production by reducing proofing and designer workload, all the while providing more control to auction managers.
