The present invention includes a personal ornament having a white coating layer and a method for making the same. The collar is at least partially formed from a resilient material that in use extends peripherally entirely around a user’s neck. The process is particularly suitable for use with supported metallocene catalyst systems in the slurry or gas phase. If the first condition of the in-memory database meets the first defined criterion, the in-memory database is stored in a persistent data store as a storage based database.
