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 Postgres. Some customers are migrating thousands of tables to Postgres in a single job.
