Tonic Subset by Tonic.ai shrinks petabytes of data down to gigabytes without breaking referential integrity, cutting storage costs and maximizing developer efficiency. It creates targeted test datasets using custom WHERE clauses or simple percentages to pull in just the data needed from across a database with a patented subsetter. Tonic Subset runs subsetting and de-identification together to minimize risk and data footprint. Virtual foreign keys capture all relationships in a database by adding foreign key constraints, and Tonic traverses foreign key dependencies to build subsets. It integrates with every leading database, from relational data to data warehouses to document-based data in MongoDB.
