DTM Data Generator
What DTM Data Generator is
DTM Data Generator creates database rows and schema objects for test databases, performance analysis, quality assurance, and load testing. It examines existing schemas and resolves master-detail key relationships, then generates values through fifteen methods. Its engine has about 70 built-in functions and an expression processor. Values can be drawn from databases, CSV and text files, Excel, XML, JSON, web resources, and user-defined scripts. Connections use ODBC, OLE DB, or Oracle Call Interface; JDBC is available with the multiplatform runtime. Supported database systems include Microsoft SQL Server, Oracle, IBM DB2, Sybase, Informix, MySQL, PostgreSQL, Interbase/Firebird, and SQLite. Results can be loaded directly into a database or exported as SQL scripts, text or CSV, XML, and JSON. XML and JSON output require Professional or Enterprise, while scrambling data is an Enterprise feature. Standard allows 128 rules per project and 10,000,000 rows per rule; higher per-rule row limits and unlimited rules are included in Professional and Enterprise. The self-hosted software supports Linux, macOS, and Windows. Demo downloads are offered for all three editions, and command-line use is available with a predefined project file.
