Mercury is the only common metal which is liquid at ordinary temperatures. Mercury is sometimes called quicksilver. It is a heavy, silvery-white liquid metal. It is a rather poor conductor of heat if compared with other metals but it is a fair conductor of electricity. It alloys easily with many metals, such as gold, silver, and tin. These alloys are called amalgams.
describe big data, so that you can speak intelligently about it when asked. So probably the main thing to recognize is this notion of the three V's of big data, which are volume, velocity and variety.
Converged, Customizable, and Extensible. Successful big data deployments continue to get bigger and more complex. With new data sources, new use cases, new workloads, and new user groups, managing that growth requires a complete understanding of what is currently happening in the system.
