EMS Data Generator for PostgreSQL is a software tool designed to create large volumes of test data for PostgreSQL database tables. It enables users to simulate production environments by generating data with customizable parameters, supporting a wide range of PostgreSQL data types, and offering both graphical and command-line interfaces. The tool can generate data for multiple tables simultaneously, maintain referential integrity, and allows users to save and edit data generation scripts without executing them directly on the server.

Key Features

Unicode support Handles international character sets for global database requirements.

• Supports multi-language data.
• Ensures compatibility with diverse datasets.

User-friendly wizard interface Guides users through the data generation process with step-by-step prompts.

• Simplifies setup for new users.
• Reduces configuration errors.

Script saving and editing Allows generated data to be saved as SQL scripts for review or modification before execution.

• Enables offline editing and auditing.
• Prevents unwanted changes to live databases.

Multi-table and multi-database support Generates data for several tables across different databases on the same host.

• Efficient for complex database environments.
• Saves time on large-scale test setups.

Comprehensive PostgreSQL data type support Handles all standard and custom PostgreSQL data types, including arrays, network addresses, geometry, bit fields, and user-defined types.

• Provides realistic data coverage.
• Supports advanced PostgreSQL features.

Flexible data generation methods Supports random, list-based, and mask-based data generation, and can use SQL query results as value sources.

• Accommodates diverse testing scenarios.
• Enables realistic data simulation.
