    Criteria for comparing test data providers

    Choosing the right Test Data Management (TDM) software is crucial for maintaining the balance between development velocity and data security in testing. To assess the different solutions available in the market as alternatives to Tonic.ai, it's important to consider several key criteria that reflect the needs of modern development environments. For this developer tools comparison, we will use the following:

    • Test data quality: This refers to how closely de-identified test data mimics production data in terms of structure, behavior, and variability, without compromising sensitive information. Capabilities to achieve high quality include complex data masking and synthetic data generation.
    • Native data source connectors: The ability of the software to seamlessly connect with various data sources directly affects its adaptability and efficiency.
    • Subsetting: The capability to create smaller, manageable versions of data sets that are still representative of the whole, while being faster and less costly to use.
    • Ephemeral data environments: The ability to provision temporary test databases that can be set up and torn down quickly, minimizing costs and resource usage.

    K2View

    4.4 Average score • ( G2: 4.4 | Gartner Peer Insights: 4.4 )

    K2View is an established player in the data integration space that more recently added data masking capabilities to enter the field of TDM. As a result of its origins, its platform approaches test data management via a less common path of entity modeling, which is ideal for data integration but can introduce complexity in test data generation.

    • Test data quality: The first step toward quality data in K2View is building out an entity model for your data, which requires you to identify and configure all relevant relationships across your databases up front. It will ensure consistency and referential integrity within your output data but at a cost in terms of up-front configuration time.
    • Native data source connectors: K2View can connect to most data sources. As a result of their entity model approach, their platform transforms connected data into their proprietary data format, rather than working natively in the format of the connected data source.
    • Subsetting: K2View’s subsetter is also tied to entity modeling, allowing you to subset based on specific business entities. It is unclear whether you can craft a subset based purely on a percentage or size to which you want to shrink your database down.
    • Ephemeral data environments: This is not a focus of K2View, given their emphasis on continuous data integration; they do not appear to offer a solution in this space.
    • Ease of use: The platform targets technically proficient users, capable of managing their data fabric approach.
    • Performance: Once fully configured, the platform performs at speed with large data environments.

    IBM Optim

    4.35 Average score • ( G2: 4.6 | Gartner Peer Insights: 4.1 )

    IBM Optim is an established player known for its data management and archiving capabilities.

    • Test data quality: IBM Optim offers standard data masking capabilities, but runs into limitations when it comes to more complex and larger scale data, making it difficult to maintain realism and relationships across tables and databases. Its support is limited when it comes to maintaining input-to-output consistency and de-identifying data types like JSON and Regex.
    • Native Data Source Connectors: Strong integration capabilities with IBM’s suite of products, though integration with non-IBM products can be less straightforward. Additionally, it does not appear to support connecting to flat files.
    • Subsetting: Not a focus of the platform; users have reported difficulties in ensuring referential integrity when subsetting in IBM Optim, requiring them to manually configure relationships between tables.
    • Ephemeral data environments: Not a core feature of IBM Optim, with more focus on persistent data management solutions.
    • Ease of use: Users cite an upfront learning curve with unclear documentation. Manual scripts are also often needed to customize the platform to meet your use cases..
    • Performance: Built for high performance in large-scale environments, though some users have flagged limitations on the number of records the platform can process per table.

    Informatica Test Data Management

    4.1 Average score • ( G2: 4.1 | Gartner Peer Insights: 4.1 )

    Informatica is a leader in data integration that acquired a test data management solution, adding TDM to its capabilities.
