National Energy Research Scientific Computing Center
<snip>
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.
<snip>
2.8 petabytes of data
Operated by 2,000 computational scientists

World Data Centre for Climate

2. You forgot the largest one - The NSA

[ChairmanAgnostic]

3. the NSA has all of those, plus mucho more.

[progressoid]

10. Yep.

I would think they dwarf the CIA database.

Of course, how can one know when even the article says of the CIA "Unknown number of classified information". One can only speculate on the size of these agencies databases.

4. ChoicePoint? I had never heard of them until now.

Very interesting article. Recommended.

5. Look up Choicepoint sometime. I did, a few years ago.

They have the ability to suck everything in, then sell it.

6. They are used for screening of the info

in employment applications and applications for renting or home owning to name a few.

It was sold to Lexis Nexis's parent company.
Here is the website:

Read wikipedia article about them:
http://en.wikipedia.org/wiki/ChoicePoint

I have heard that they also will compare info that people send in at different times such as applying for jobs even several years apart. They flag even tiny discrepancies which can be used to judge someone.

Read the articles and look at their site. They are truly scary.

7. Is Google earth part of the Google database?

8. They forgot Wal-Mart

http://www.eweek.com/c/a/Enterprise-Applications/At-WalMart-Worlds-Largest-Retail-Data-Warehouse-Gets-Even-Larger/

In 2004(!) they had 500 terabytes of data.

9. My to-do list /nt

11. What about the Mormons and their Genealogy data store?

I thought they had data on every man, woman, and child ever born squirreled away in some mountain cave somewhere. Maybe its all in filing cabinets and does not meet the criteria to be considered a database.
