World Record:10-Table Join Across 10 Systems

Updated: Oct 31

Survival is not the norm; it's the exception. Humans have evolved more than any other species on Earth. Plants, insects, fish, and other mammals are beautiful, but humans are the dominating force.

Nothing evolves faster in today's world than business because of the power of data and analytics. A company's survival and the survival of your career should never be taken for granted. If the tool you use to access data is not federated, it is underrated because tools need to evolve over time.

Below is a video of a ten-table join across ten systems in a single query. You will be shocked at the genius behind the architecture for federated queries.

It's not that I started my career by programming for ten years, wrote 85 books on all database platforms, or taught over 1,000 classes to the largest companies in their industry.

It's because I did all of the above and then set my sites on building the greatest software the world would ever know, then spent 20 years developing and evolving the product.

Nobody had the vision longer and was willing to sacrifice more than I did because I knew it was inevitable that data would evolve and become so important and so massive that everyone would one data need to access data across hundreds of systems.

I took no shortcuts. I know data, and if you can't join data across systems in the blink of any eye, your company and your career are in danger because neither is evolving fast enough.

Write me back or give me a call so we can set you up to try Nexus today. Then, it will no longer be about survival because you will dominate.

Yours in all data,


Here is the video of ten tables joining across ten database systems in a single query. Warning: This video contains what many experts thought was impossible.

Tom Coffing has also led a team of developers for almost 20 years to create the Nexus, which queries, migrates, and joins data across all systems. Amazingly, Nexus migrates between all the databases below with the click of the mouse.


• Excel

• Microsoft Access

• Snowflake

• Redshift

• Synapse

• BigQuery

• Teradata

• Oracle

• SQL Server

• DB2

• Hadoop

• MapR

• Greenplum

• Postgres

• Vertica

• Netezza


• Yellowbrick

• SQLite

The picture above shows Nexus in dark mode migrating Oracle data to Snowflake. Some customers are migrating thousands of tables to Snowflake in a single job.

Watch Sherry and Sandy's bold moves to meet their cloud migration deadline.
