Fine-tuning the Data Generation Process

Data Generator offers several distribution modes that allow you to fine-tune the data generation process. You can generate data by the specified number of rows, by the time specified, using a linked table, populating tables that already contain some data, or specifying the exact number of rows. These options provide you with the flexibility to tailor the data generation process to your specific needs.

In addition, you can customize individual generators for each supported data type. This includes setting the number of NULL rows, empty rows, defining data uniqueness, value ranges, and value distribution mode. These customization options ensure that the generated data closely mimics the characteristics of your actual data, thereby enhancing the realism and usefulness of your test data.

By leveraging these features and capabilities, you can create realistic test data in PostgreSQL effortlessly and efficiently.
