hrough your life, you may have come across some very large collections.
These collections can vary from things that you use in your day to day
life to things such as stones or even bugs. You also might have met with
some of the organizations having large databases like Google and
Facebook who are nearing to a billion users. So now the question- what
is a database? Well databases are nothing but massive collection of
billions and trillions of information’s that are in the forms of fields
and records and on how they are being stored and served.
To justify the old saying that “Size alone doesn’t matters”, databases are merely not listed according to their sizes. It depends on their storage and service. So keeping this in mind here’s a list that features top 10 Largest Databases in the World.
1. The World Data Centre for Climate:
With a massive 220 terabytes of data, it’s the World Data Centre for Climate (WDCC) who bags the coveted number one spot in our list that features top 10 largest databases across the globe. WDCC, operated by the Max Planck Institute for Meteorology and German Climate Computing Centre, also are the proud owners of a supercomputer worth 35 million Euros. Excluding the 220 terabyte, which are accessible across the web; the WDCC also has an additional 110 terabytes of data that are mainly used for climate simulation and 6 petabytes of extra data’s that are stored in magnetic tapes for easy access.
2. National Energy Research Scientific computing Center:
The National Energy Research Scientific Computing Center (NERSC) based in Oakland, California has a unique kind of database that non others can even think of. The NERSC database comprises a mammoth 2.8 petabytes of information that vary from atomic energy research, high energy physics experiments to simulations of our early universe. The NERSC which are owned and operated by the Lawrence Berkeley National Laboratory and the U.S Department of Energy, has the second largest database in the world with a whole lot of information that are handled by a minimum of 2,000 computational scientists.
