10 Largest online databases

Library of infinity



Talking about infinit numbers of multimedia! Can you imagine combining "multi" and "infinit" in the same sentence, so how much am i talking about?



All of us have tried to collect items in our childhood and maybe even now. But of course we can reach a huge number but not even close to infinity. We might do pir best to collect as much songs we could on our computers, but still, limited. If so, could there be somwhere an infinit number of data?! Many has confirmed that the closest to an "infinit library" is the internet. So in this post i would like to list the largest databases on our beloved net.



The question to be asked... could there be a limit to storage? or is infinity the number that we will reach?







10. Library of Congress:


Library of Congress (LC) boasts more than 130 million items ranging from cook books to colonial newspapers to U.S. government proceedings. 20 Terabytes of data.


9. Central Intelligence Agency


The CIA, do i have to explain? Of course, there is an unknown number of information in this database, and the exact number of size is remained mysterious, but it is known that each month 100 Freedom of Information Act (FOIA) items are added with comprehensive statistics of 250 countries.


8. Amazon


A pretty famous database; Which is the largest retail store online. Containing more that 54 million customers worldwide, and more that 42 database of data.


7. YouTube


Another famouse database; Known for storing videos. It contains at least 45 terabytes of videos. "Given: 65,000 videos per day X 30 days per month = 1,950,000 videos per month; 1 terabyte = 1,048,576 megabytes. If we assume that each video has a size of 1MB, YouTube would expect to grow 1.86 terabytes next month. Similarly, if we assume that each video has a size of 10MB, YouTube would expect to grow 18.6 terabytes next month."


6. ChoicePoint


Imagine if this ChoicePoint database is a book, and you would have to search in a book of a billion pages for a phone number! This database contains information of 250 million people which leads to a big number of 250 terabytes of personal data! Are you able to comprehend the numbers?
5. Sprint


One of the largest telecommunication companies. It offers services to more than 53 million subscribers. 365 million call record processed by day, 70 thousand call detail recorded per second.
4. Google


Everybody knows "Google". This blog would be made if it werent for google. 91 million searches per day (Among them me!), with a countless number of users.
3. AT&T


Similar to "Sprint", the United States' oldest telecommunications company AT&T maintains one of the world's largest databases. Containing 1.9 trillion phone call record leading to a database of 323 terabytes of information.


2. National Energy Research Scientific Computing Center


The second largest database in the world, National Energy Research Scientific Computing Center (NERSC) in Oakland, California, is owned by Lawrence Berkeley National Laboratory and the U.S. Department of Energy. Now we have reached a new number, we now can use the peta! For this database has 2.8 petabytes of data that is operated by 2,000 computational scientists.


1. World Data Centre for Climate

Operated by the Max Planck Institute for Meteorology and German Climate Computing Centre, The World Data Centre for Climate (WDCC) is the largest database in the world. Our winner has 220 terabytes of web data and 6 petabytes of additional data!

So if you ask me: Did we reach infinity yet? Now you can answer for yourself!
