World Record! Nexus Does 20-Table Join Across 20 Systems

Updated: Jan 26, 2023

For almost 30 years, the largest companies in their vertical have trusted Tom Coffing and the Nexus for their data warehouse books, training, and software. Tom's Nexus development team has been evolving and improving the product for 18 years with a mission to query all systems, migrate data between any two systems, and join data across all systems.

Business users who are not technical love Nexus because Nexus builds the SQL for the user. IT love Nexus because they can develop on any system and build solutions that support its customers, who can point and click to receive the analytics they need. The ETL teams love Nexus because they can automatically migrate thousands of tables quickly, and the DBA teams love Nexus because they can manage all systems in their enterprise.

Nexus performs a 20-table join across 20 database systems in a single query.

Please get in touch with me directly to learn more about bringing Nexus into your company.
