Testing on full production copies is slow, expensive and risky. Testing on generic dummy data means missing the real-world cases that crash an application in production. Most teams swing between these two extremes and pay the price in both quality and time. DOT Extract<\/a> resolves exactly this tension.<\/span><\/p>\n<\/div><\/div><\/div> Key takeaways<\/span><\/p>\n<\/div> DOT Extract generates targeted, lightweight datasets that reflect the real diversity of production data, instead of copying the entire database.<\/p>\n<\/div><\/li> Relationships between tables and across sources are preserved, and can even be recreated virtually when the source database declares none.<\/p>\n<\/div><\/li> Combined with DOT Anonymizer, DOT Extract secures non-production environments and helps meet GDPR, NIS 2, DORA, Law 25 and the FADP.<\/p>\n<\/div><\/li><\/ul><\/div><\/div> DOT Extract is a test data extraction solution<\/a><\/strong> that generates realistic, consistent datasets \u2014 small<\/strong> enough to support fast test cycles, yet large enough<\/strong> to faithfully reflect the variety of production data.<\/p>\n The principle: rather than copying the entire database, you intelligently sample a representative subset.<\/p>\n The solution is part of ARCAD Software's DOT suite<\/a>, backed by 34 years of DevSecOps leadership, covering the full test data management lifecycle: discovery<\/a>, extraction<\/a>, masking and anonymization<\/a>.<\/p>\n<\/div> Where many tools simply extract \"everything or a percentage,\" DOT Extract<\/a> delivers targeted, lightweight datasets that still capture the real diversity of the data.<\/p>\n<\/div> Relationships between tables and across sources are maintained, ensuring consistent, usable data. And when the source database carries no declared relationships \u2014 a very common case on legacy systems \u2014 DOT Extract<\/a> can create or import virtual relationships and run consistent sampling on that basis. You get reliable datasets, even where the database schema doesn't help.<\/p>\n<\/div> DOT Extract<\/a> integrates with DB2\/z, DB2i, DB2 LUW, Oracle, SQL Server (including the Azure version), MySQL<\/a>, PostgreSQL<\/a>, Informix, MongoDB and MariaDB \u2014 from legacy mainframe environments to modern relational and NoSQL databases.<\/p>\n<\/div> DOT Extract<\/a> pairs with DOT Anonymizer<\/a> to extract and anonymize in a single pipeline. Everything starts from a copy of production, delivering realistic data without exposing the live database. From this multi-DBMS source, the system generates a targeted sample<\/strong>: small, but true to the real variety of the data. This sample can then optionally pass through DOT Anonymizer to mask sensitive data<\/a>. The result is made available to non-production environments (UAT, development, business intelligence, training), which finally get relevant, consistent and compliant datasets \u2014 with zero risk to production (fig. 1).<\/p>\n<\/div> Figure 1 \u2014 The data journey, from pre-production to test environments.<\/p><\/div><\/div><\/div> DOT Extract<\/a> helps you meet the requirements of GDPR<\/a>, NIS 2<\/a>, DORA<\/a>, Law 25<\/a> and the Swiss FADP<\/a> by reducing the exposure of sensitive data outside production.<\/p>\nWhat is DOT Extract?<\/h2><\/div>
