Top 10 Largest Databases in the World
We all collected things as children. Rocks, baseball cards, Barbies, perhaps even bugs -- we all tried to gather up as much stuff as possible to compile the biggest most interesting collection possible. Some of you may have even been able to amass a collection of items numbering into the hundreds (or thousands).
As the story always goes, we got older, our collections got smaller, and eventually our interests died out...until now.
There are currently organizations around the world in the business of amassing collections of things, and their collections number into and above the trillions. In many cases these collections, or databases, consist of items we use every day.
In this list, we cover the top 10 largest databases in the world:
10. Library of Congress
Not even the digital age can prevent the world's largest library from ending up on this list. The Library of Congress (LC) boasts more than 130 million items ranging from cook books to colonial newspapers to U.S. government proceedings. It is estimated that the text portion of the Library of Congress would comprise 20 terabytes of data. The LC expands at a rate of 10,000 items per day and takes up close to 530 miles of shelf space -- talk about a lengthy search for a book.
If you're researching a topic and cannot find the right information on the internet, the Library of Congress should be your destination of choice. For users researching U.S. history, around 5 million pieces from the LC's collection can be found online at American Memory.
Unfortunately for us, the Library of Congress has no plans of digitizing the entirety of its contents and limits the people who can check out materials to Supreme Court Justices, members of Congress, their respective staff, and a select few other government officials; however, anyone with a valid Reader Identification Card (the LC's library card) can access the collection.
By the Numbers
- 130 million items (books, photographs, maps, etc)
- 29 million books
- 10,000 new items added each day
- 530 miles of shelves
- 5 million digital documents
- 20 terabytes of text data
9. Central Intelligence Agency
The Central Intelligence Agency (CIA) is in the business of collecting and distributing information on people, places and things, so it should come as no surprise that they end up on this list. Although little is known about the overall size of the CIA's database, it is certain that the agency has amassed a great deal of information on both the public and private sectors via field work and digital intrusions.
Portions of the CIA database available to the public include the Freedom of Information Act (FOIA) Electronic Reading Room, The World Fact Book, and various other intelligence related publications. The FOIA library includes hundreds of thousands of official (and occasionally ultra-sensitive) U.S. government documents made available to the public electronically. The library grows at a rate of 100 articles per month and contains topics ranging from nuclear development in Pakistan to the type of beer available during the Korean War. The World Fact Book boasts general information on every country and territory in the world including maps, population numbers, military capabilities and more.
By the Numbers
- 100 FOIA items added each month
- Comprehensive statistics on more than 250 countries and entities
- Unknown number of classified information
8. Amazon
Amazon, the world's biggest retail store, maintains extensive records on its 59 million active customers including general personal information (phone number address, etc), receipts, wishlists, and virtually any sort of data the website can extract from its users while they are logged on. Amazon also keeps more than 250,000 full text books available online and allows users to comment and interact on virtually every page of the website, making Amazon one of the world's largest online communities.
This data coupled with millions of items in inventory Amazon sells each year -- and the millions of items in inventory Amazon associates sell -- makes for one very large database. Amazon's two largest databases combine for more than 42 terabytes of data, and that's only the beginning of things. If Amazon published the total number of databases they maintain and volume of data each database contained, the amount of data we know Amazon houses would increase substantially.
But still, you say 42 terabytes, that doesn't sound like so much. In relative terms, 42 terabytes of data would convert to 37 trillion forum posts.
By the Numbers
- 59 million active customers
- More than 42 terabytes of data
7. YouTube
After less than two years of operation YouTube has amassed the largest video library (and subsequently one of the largest databases) in the world. YouTube currently boasts a user base that watches more than 100 million clips per day accounting for more than 60% of all videos watched online.
In August of 2006, the Wall Street Journal projected YouTube's database to the sound of 45 terabytes of videos. While that figure doesn't sound terribly high relative to the amount of data available on the internet, YouTube has been experiencing a period of substantial growth (more than 65,000 new videos per day) since that figures publication, meaning that YouTube's database size has potentially more than doubled in the last 5 months.
Estimating the size of YouTube's database is particularly difficult due to the varying sizes and lengths of each video. However if one were truly ambitious (and a bit forgiving) we could project that the YouTube database will expect to grow as much as 20 terabytes of data in the next month.
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.
By the Numbers
- 100 million videos watched per day
- 65,000 videos added each day
- 60% of all videos watched online
- At least 45 terabytes of videos
6. ChoicePoint
Imagine having to search through a phone book containing a billion pages for a phone number. When the employees at ChoicePoint want to know something about you, they have to do just that. If printed out, the ChoicePoint database would extend to the moon and back 77 times.
ChoicePoint is in the business of acquiring information about the American population -- addresses and phone numbers, driving records, criminal histories, etc., ChoicePoint has it all. For the most part, the data found in ChoicePoint's database is sold to the highest bidders, including the American government.
But how much does ChoicePoint really know? In 2002 ChoicePoint was able to help authorities solve a serial rapist case in Philadelphia and Fort Collins after producing a list of 6 potential suspects by data mining their DNA and personal records databases. In 2001 ChoicePoint was able to identify the remains of World Trade Center victims by matching DNA found in bone fragments to the information provided by victim's family members in conjunction to data found in their databases.
By the Numbers
- 250 terabytes of personal data
- Information on 250 million people
5. Sprint
Sprint is one of the world's largest telecommunication companies as it offers mobile services to more than 53 million subscribers, and prior to being sold in May of 2006, offered local and long distance land line packages.
Large telecommunication companies like Sprint are notorious for having immense databases to keep track of all of the calls taking place on their network. Sprint's database processes more than 365 million call detail records and operational measurements per day. The Sprint database is spread across 2.85 trillion database rows making it the database with the largest number of rows (data insertions if you will) in the world. At its peak, the database is subjected to more than 70,000 call detail record insertions per second.
By the Numbers
- 2.85 trillion database rows.
- 365 million call detail records processed per day
- At peak, 70,000 call detail record insertions per second
4. Google
Although there is not much known about the true size of Google's database (Google keeps their information locked away in a vault that would put Fort Knox to shame), there is much known about the amount of and types of information Google collects.
On average, Google is subjected to 91 million searches per day, which accounts for close to 50% of all internet search activity. Google stores each and every search a user makes into its databases. After a years worth of searches, this figure amounts to more than 33 trillion database entries. Depending on the type of architecture of Google's databases, this figure could comprise hundreds of terabytes of information.
Google is also in the business of collecting information on its users. Google combines the queries users search for with information provided by the Google cookies stored on a user's computer to create virtual profiles.
To top it off, Google is currently experiencing record expansion rates by assimilating into various realms of the internet including digital media (Google Video, YouTube), advertising (Google Ads), email (GMail), and more. Essentially, the more Google expands, the more information their databases will be subjected to.
In terms of internet databases, Google is king.
By the Numbers
- 91 million searches per day
- accounts for 50% of all internet searches
- Virtual profiles of 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. Architecturally speaking, the largest AT&T database is the cream of the crop as it boasts titles including the largest volume of data in one unique database (312 terabytes) and the second largest number of rows in a unique database (1.9 trillion), which comprises AT&T's extensive calling records.
The 1.9 trillion calling records include data on the number called, the time and duration of the call and various other billing categories. AT&T is so meticulous with their records that they've maintained calling data from decades ago -- long before the technology to store hundreds of terabytes of data ever became available. Chances are, if you're reading this have made a call via AT&T, the company still has all of your call's information.
By the Numbers
- 323 terabytes of information
- 1.9 trillion phone call records
2. National Energy Research Scientific Computing Center
The second largest database in the world belongs to the National Energy Research Scientific Computing Center (NERSC) in Oakland, California. NERSC is owned and operated by the Lawrence Berkeley National Laboratory and the U.S. Department of Energy. The database is privy to a host of information including atomic enegry research, high energy physics experiements, simulations of the early universe and more. Perhaps our best bet at traveling back in time is to fire up NERSC's supercomputers and observe the big bang.
The NERSC database encompasses 2.8 petabytes of information and is operated by more than 2,000 computational scientists. To put the size of NERSC into perspective, the total amount of spoken words in the history of humanity is estimated to be at 5 exabytes; in relative terms, the NERSC database is equivalent to 0.055% of the size of that figure.
Although that may not seem a lot at first glance, when you factor in that 6 billion humans around the globe speak more than 2,000 words a day, the sheer magnitude of that number becomes apparent.
By the Numbers
- 2.8 petabytes of data
- Operated by 2,000 computational scientists
1. World Data Centre for Climate
If you had a 35 million euro super computer lying around what would you use it for? The stock market? Building your own internet? Try extensive climate research -- if there's a machine out there that has the answer for global warming, this one might be it. 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.
The WDCC boasts 220 terabytes of data readily accessible on the web including information on climate research and anticipated climatic trends, as well as 110 terabytes (or 24,500 DVD's) worth of climate simulation data. To top it off, six petabytes worth of additional information are stored on magnetic tapes for easy access. How much data is six petabyte you ask? Try 3 times the amount of ALL the U.S. academic research libraries contents combined.
By the Numbers
- 220 terabytes of web data
- 6 petabytes of additional data
* Additional Databases
The following databases were unique (and massive) in their own right, and just fell short of the cut on our top 10 list.
Nielsen Media Research / Nielsen Net Ratings
Best known for its television audience size and composition rating abilities, the U.S. firm Nielsen Media Research is in the business of measuring mass-media audiences including television, radio, print media, and the internet. The database required to process such statistics as Google's daily internet searches is nothing short of massive.
Myspace
It would seem appropriate that the world's largest social networking site, Myspace, has a rather large database to keep up with all of its user's content.
United States Customs
The U.S. Customs database is unique in that it requires information on hundreds of thousands of people and objects entering and leaving the United States borders instantaneously. For this to be possible, the database was special programmed to process queries near instantaneously.
HPSS
There are various databases around the world using technology similar to that found in our countdown's second largest database NERSC. The technology is known as High Performance Storage System or HPSS. Several other massive HPSS databases include Lawrence Livermore National Laboratory, Sandia National Laboratories, Los Alamos National Laboratory, Commissariat a l'Energie Atomique Direction des Applications Militaires, and more.

Posted by: Sime | Feb 15, 2007 5:31:16 PM
This list can't be exhausting.
We're not on it, for example, and we have more than 300TB of photos. We're growing at >1TB per day.
I seriously doubt we're on the Top 10 list, either, which means lots of these entries don't belong.
Let's not forget, for example, that the Internet Archive came up with a platform for their storage called the Petabox: http://www.archive.org/web/petabox.php
But they're not on the list.
Posted by: Don MacAskill | Feb 15, 2007 5:31:16 PM
Hold on just a sec - 220 terabytes is less than 1 petabyte (which is defined as 1024 terabytes).
You've gotta rearrange these databases.

What would be *really* interesting is to know the underlying technology that runs these massive databases. I doubt it's MySQL... but that would be freakin' cool. Now that I ponder that thought, I wonder what's the largest MySQL database currently out there....

This is crap. Fermilab has 5 petabytes alone of collected events and Monte Carlo events in it's enstore database. Now if we start including the fact that CERN will be part of this, you're way larger then any of this. If you're going to make a top 10 list you should actually go out and search for the top 10. What a bunch of crap.

I think you're taking it a little too serious to clammer and hoo-haw about how this isn't exhaustive. Pretty much the only ones without any estimated stats were the top two. Anyway, this was a really interesting on what the hugest amounts of data in the world are storing. It makes you wonder, how well does the combined storage of everyone's personal computers stack up compared to databases...

At the SMALL art studio where I work, we've got about 5 terabytes of storage on external harddrives and dvd's... this is a business with 1 artist and 2 employees. I can only imagine the hundreds of corporate businesses that have more than the 8-10 positions on this list.
It's like John Dvorak says - any top 10 list (or top whatever) is typically a bunch of popular jaw-dropping names thrown together during a lunch meeting.

I find it unlikely that YouTube includes their flash videos as binary large objects (blobs) in the database. More likely, they keep some pointer information that tells the application where to find the video files.
That would shrink the size of their database by several orders of magnitude. Gigabytes instead of terabytes.
Posted by: Johnny Fuery | Feb 15, 2007 6:46:09 PM
David, this is a list of database sizes. I don't think the data your art studio is storing is databases.

Where is Walmart? about 10 years ago they had one of the top 10 databases and they are growing everyday and I know even 10 years ago they were over 20TB.
Posted by: James Dickens | Feb 15, 2007 7:18:57 PM
You guys seem to miss the point that the definition of a database is "A database is a collection of data that is organized so that its contents can easily be accessed, managed and updated.", and although the term originated from the electronic storage of information in this way the word has been adapted to a generic definition of "A collection of data that is organized and easily retrievable."
So that is why anything can be included, I do have to admit however that alot of these dont belong on the top 10 list.
Posted by: Eric | Feb 15, 2007 7:22:21 PM
Sci-Tech had Google, AOL, Hotmail and Yahoo all above a Petabyte.
http://www.sci-tech-today.com/perl/story/19162.html
That's nothing. Article claims the genome centres are sharing over 7 Petabytes with Universities and that life sciences data is increasing faster than any other data source.

I know of at least one service that's absent from this list that is well over 10 petabytes. The average geek's desktop running Vista or Leopard will have a search index covering tens of terabytes in a year or two, I would expect the big boys to be talking exabytes by now.

I'm suprised that MySpace got a mension when hotmail didn't.
Hotmail has been around for atleast 8 years and probably had more people sign up for it than myspace and you tube put together.
There probably the number one target for spam as well.

I'm not suprised that Wiki wasn't on there, after all it's a program for managing content. The providers of that content are all individual organisations with individual servers. Wiki shouldn't be the sum of all Wiki pages everywhere.

Posted by: Andreas Maratheftis | Feb 16, 2007 4:09:30 AM
What about databases in other parts of the world than the US ?
at CERN alone, in Geneva, they reached their 1st Petabyte as early as 1998 and planned to have collected 10 petabytes of particle accelerator's data by 2003.
These numbers and estimations are completely unimpressive.

I am most impressed with the Library of Congress. To be considered for this list with over 100 million physical items that you can touch and see is unbelievable. The average person has no concept of 50 terabytes or 2 petabytes or whatever.

"Hold on just a sec - 220 terabytes is less than 1 petabyte (which is defined as 1024 terabytes). You've gotta rearrange these databases." -Mark
I guess he meant to say that it was 6 petabytes, and they keep 220 TB for quick access.
Posted by: rolandog | Feb 16, 2007 7:08:23 AM
While it's fun that you've tried to put these databases in order, it seems rather arbitrary to put the Library of Congress - a place dedicated to assembling all books published in a relevant manner, to a database that collects a seemingly endless stream of raw data on weather reports world wide. It's the difference of putting someone with a lot knowledge next to someone with a lot of wisdom. It's not a just comparison. Sure, one might have more terabytes/know more facts but that doesn't mean it has any right to be higher up on any list. I'd be more curious to see a list of the largest collections of human knowledge (lexus nexus, library of congress, etc.) or any other list determined by far less arbitrary measures then raw size. And if you're determined to do raw size I'd do a bit more research first. All the same-a fun read for some items. Thanks for taking the time.

I'm surprised CERN weren't at least considered.. granted they might not have "much" in the way of records (rows) compared with, say, google, but they sheer size of the data has got to be in the 10s of TB
Posted by: Peter | Feb 16, 2007 8:13:09 AM
Although it'd be unreasonable to assume that every DB in the world can be equally measured, I found one site / company that does a good comparison every couple of years. It's voluntary though, so google likely won't be in such a list.
Wintercorp has also their test method on their site that explains that they require specific vendor-provided scripts to be run to have machine generated data in order to compete in their DB size contests.

How about hotmail? i believe it has a lot more
for user accounts and mails for each account.
Also, the telephone based companies also have
lots data because each call data record is a
record (that includes you turn on and off the cellphone), so, the company such as Chinese Mobile should be in the list as well simply it has larger users. Also, the China government who
tries to collect all citizens data should be
calculated as well.

CERN with 10's of terabytes? Let me tell you that universities have 10's of terabytes easy. Hell I have a data server with 4 terabytes just for a group of 10 of us. CERN, FERMILAB these are places with large databases. We're talking about 10's of petabytes of fast access data delivered on demand. When the LHC turns on the 10 on this list will look like an ipod. You want to talk about large databases, talk to the astrophysicists and particle physicists.

This article should have been entitled "An uneducated guess at the top 10 American databases". Still entertaining and a good read though.

So, if Sprint has 2.85 trillion rows total, but Google produces 33 trillion per year? How does that make Sprint have the largest number of rows?

Posted by: David Wells | Mar 16, 2007 7:45:06 AM
Hmmm... There should be Yahoo... here it has countless users and also huge search engine can some one get the Yahoo DB size.... ??

An interesting list. The Library of Congress is a marvelous resource. A larger catalog of library resources (which includes the Library of Congress catalog) is worldcat.org from OCLC, the world's largest library cooperative.

People don't tend to talk about all of the data they have. Medical fiend for example with some scans can create huge amounts of data. Wouldn't surprise me that in next 10 years the larger hospitals might start to rival the NSA for total database volumes.
Interesting list but as Dr Phil would say "That dog don't walk boy".

SLAC had half a petabyte in 2002, now it is well over 2 petabytes. We are now building O(100) petabyte database for astronomers.

As in my opinion , shelfs and books are not databases. Are bookbases :) . Any way, google has the biggest database. Not only the search database, the gmail , maps , documents, patents, etc.....

I understand that the largest database in Europe is the vehicle movement and associated number plate recognition database in the UK, which is purported to hold the last 13 months of vehicle movement data for every police operated vehicle tracking camera in the country.
Am I right? Any comments?
