The technique uses production data as input and outputs sample data in the same relational schema while preserving the integrity of joins of the different tables in the schema. For a given relational schema, the master tables are found. Then a subset is created by placing selection criteria in a query defining how to sample the data for these master tables. Following the joins, the dependent tables are added to the query automatically."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Database consistent sample data extraction","description":"Various embodiments of systems and methods for database consistent sample data extraction are described herein.
