Why Trust Our Software Reviews

DTM Data Generator Overview

DTM Data Generator offers extensive data generation options and strong database compatibility, making it a solid choice for teams needing granular control over test data. Its pricing is straightforward, and support is responsive, but the interface feels dated and onboarding can take time. Compared to others, it excels in customization and scripting but lacks modern UI and built-in integrations. It’s best for users who prioritize flexibility and need to simulate complex data scenarios, such as QA engineers or database administrators working in regulated or legacy-heavy environments. For those judging tools on depth over aesthetics, it’s a reliable pick.

Our Review Methodology

How We Test & Score Tools

We’ve spent years building, refining, and improving our software testing and scoring system. The rubric is designed to capture the nuances of software selection and what makes a tool effective, focusing on critical aspects of the decision-making process.

Below, you can see exactly how our testing and scoring works across seven criteria. It allows us to provide an unbiased evaluation of the software based on core functionality, standout features, ease of use, onboarding, customer support, integrations, customer reviews, and value for money.

Core Functionality (25% of final scoring)

The starting point of our evaluation is always the core functionality of the tool. Does it have the basic features and functions that a user would expect to see? Are any of those core features locked to higher-tiered pricing plans? At its core, we expect a tool to stand up against the baseline capabilities of its competitors.

Standout Features (25% of final scoring)

Next, we evaluate uncommon standout features that go above and beyond the core functionality typically found in tools of its kind. A high score reflects specialized or unique features that make the product faster, more efficient, or offer additional value to the user.

We also evaluate how easy it is to integrate with other tools typically found in the tech stack to expand the functionality and utility of the software. Tools offering plentiful native integrations, 3rd party connections, and API access to build custom integrations score best.

Ease of Use (10% of final scoring)

We consider how quick and easy it is to execute the tasks defined in the core functionality using the tool. High scoring software is well designed, intuitive to use, offers mobile apps, provides templates, and makes relatively complex tasks seem simple.

Onboarding (10% of final scoring)

We know how important rapid team adoption is for a new platform, so we evaluate how easy it is to learn and use a tool with minimal training. We evaluate how quickly a team member can get set up and start using the tool with no experience. High scoring solutions indicate little or no support is required.

Customer Support (10% of final scoring)

We review how quick and easy it is to get unstuck and find help by phone, live chat, or knowledge base. Tools and companies that provide real-time support score best, while chatbots score worst.

Customer Reviews (10% of final scoring)

Beyond our own testing and evaluation, we consider the net promoter score from current and past customers. We review their likelihood, given the option, to choose the tool again for the core functionality. A high scoring software reflects a high net promoter score from current or past customers.

Value for Money (10% of final scoring)

Lastly, in consideration of all the other criteria, we review the average price of entry level plans against the core features and consider the value of the other evaluation criteria. Software that delivers more, for less, will score higher.

Core Features

Multi-Database Support

Generate test data for Oracle, SQL Server, MySQL, PostgreSQL, and more. This flexibility lets you use one tool across different environments.

Custom Data Generation Scripts

Create complex data sets using SQL expressions, templates, and scripts. This allows you to match real-world data patterns and business rules.

Automatic Foreign Key Handling

Preserve referential integrity by automatically generating related records. This is essential for testing applications with complex relational databases.

70+ Built-In Data Generators

Access a wide range of data types, including names, dates, emails, and custom formats. This speeds up the process of creating realistic, varied test data.

Command-Line Automation

Run data generation tasks from the command line for batch processing. This supports automated testing workflows and scheduled data refreshes.

Project and Scenario Management

Save and reuse data generation projects and scenarios for consistency. This feature helps teams standardize test data across multiple test cycles.

Ease of Use

DTM Data Generator’s interface feels dated and can be overwhelming for new users, especially those without strong SQL or scripting experience. While its feature set is deep and highly configurable, the navigation and setup process require patience and technical know-how. Users often mention that once configured, it’s reliable and flexible, but the initial learning curve and lack of modern UI elements make it less approachable than many newer and more user-friendly database testing tools.

Integrations

DTM Data Generator integrates with Oracle, Microsoft SQL Server, MySQL, PostgreSQL, IBM DB2, Azure SQL, SQLite, Interbase, and Sybase, among others.

DTM offers several APIs through their Data Generation SDK for different levels of services.
