Interesting characteristics include: Fast: Relational Data Generator can generate million records in a matter of seconds. Repeatable: each run will produce the same data again. (It is possible to change this behavior in the project settings page). Convenient: it comes with standard generators for common data, for instance: First/Last names; Addresses, cities, countries; Email addresses, phones numbers; IP/MAC addresses. Easy to use: generators can be entirely configured using the graphical interface. There are no arcane Domain Specific Languages, or configuration files to fiddle with. Developer-friendly: once the project has been configured in the graphical interface, it can be integrated easily via a Command Line Interface.
