The Top 10 Largest Databases in the World: Past and Present 

The ranks of the top 10 largest databases in the world have exploded immensely since the inception of cloud-based CRM storage solutions. Businesses and organizations no longer had to maintain their own storage servers when storage giants such as Amazon Web Services can host your data for you. Even though the largest database in the world has grown and evolved in current times and seems to show no sign of stopping, it is also fascinating to explore the largest database in the world from the early 2000s.  

It is fascinating to observe how the largest databases from the past were oriented more towards gathering and storing data for big corporations and government entities while the largest database of the present is far more accessible and has bridged the gap for smaller operations that may not be able to handle the infrastructure required to maintain such databases. Modern CRM software solutions are becoming more commonplace with companies noticing the importance of data hence, the need for maintaining independent databases within companies is becoming apparent. This is where the current largest database in the world comes in handy.

These days there are serious concerns about data security and testing in these largest database of the world. Without strict data measures and the assurance that customer data is and privacy is respected at all times, CRM security has had to improve a lot in recent years.

The biggest difference in the largest database in the world during present times is how they are measured. Instead of the size of storage and how big of an audience each largest database in the world serves, the newer largest database in the world is judged according to its ranking.

Microsoft SQL Server

Citus Data, a PostgreSQL extension, allows distributed SQL features to allow transactional guarantees in the business. Partial index, bloom filters, and non-blocking are also popular features of this largest database in the world.

Semi-structured data needs are the best use for this largest database in the world. It possesses several free (Community Server), commercial (Enterprise Server), and cloud services (Atlas) and horizontal scaling for its users.

Library of Congress

The digital age couldn’t prevent the largest database in the world from ending up on this list. The Library of Congress (LC) boasts more than 173 million items (including over 53 million books) ranging from cookbooks to colonial newspapers to U.S. government proceedings.

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 largest database in the world 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.

Central Intelligence Agency

The Central Intelligence Agency (CIA) is one of the largest database in the world that was well known 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’s largest database in the world 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 largest database in the world library contains topics ranging from nuclear development in Pakistan to the type of beer available during the Korean War.

Amazon, the world's biggest retail store, maintains the largest database in the world of extensive records on its 300 million active customers including general personal information (phone number address, etc), receipts, wish lists, and virtually any sort of data the website can extract from its users while they are logged on. Amazon still keeps the largest database in the world of more than 33 million titles available online and allows users to comment and interact on virtually every page of the website, making Amazon one of the largest database in the world.

This data coupled with millions of items in inventory Amazon sells each year -- and the millions of items in inventory Amazon associates sell – made for one of the largest database in the world. If Amazon had published the total number of largest database in the world they maintain and the volume of data each database contained, the amount of data we knew Amazon houses would increase substantially.
