    For running application tests it's well suited. H2 [Database Engine] can replace the real-world database solution for them easily and removes the requirement to set up a a separate database instance just for running unit tests. For using in actual production application one needs to consider scale. H2 is suitable if application runs in single instance and database is located in same machine as a file where that application runs. This means the application shouldn't have a large user base. However it's easy to switch to an actual MySQL instance if the need arises, it's most likely only a configuration change and doesn't require new code.

    Cons
    Open Source
    • There's a warning in official FAQ "Is it Reliable?"-section which makes it seem like H2 is not yet a mature product.
    • If raw SQL queries are used there maybe be differences between MySQL & H2. ORM library should be used.
    • Support seems to be community-based only.

    • It is very difficult to find a missing functionality in Informix, technically is great. I will again criticize the business side and how it has been managed over the past, I hope this could be improved with HCL's help. I know they are working hard, but we need to start letting the world know and revert their concept about its existence and that it is one of the best competitors within the data treatment, in the market. We need to start telling the world about success cases and stories showing this and backing up its strong technology.

    Server management is easy enough to be able to embed the engine in a device and let it run for years without maintenance.

    While both can run as an in-memory database, H2 Database Engine was just so much easier for us to use since we primarily use the Java stack and H2 Database Engine is also built with Java.

    Return on Investment
    Open Source
    • Doesn't take time from developers, once it's configs are set up for testing it works in everyone's development environments
    • Easy to integrate in application, no need to setup separate database software, no maintenance
    • No need to deal with infrastructure related issues/costs - database runs in same machine as the application that uses it.

    • Although I do not own nor have visibility on my company's figures:
    • Informix generates consistent savings on DBA staffing, no need for many DBAs as other DBMS require.
    • The replication architecture allowed consistent savings in the infrastructure as well as developments and maintenance, the job is already done, no need to develop complex and costly solutions, it's just a matter of configuring it.
    • The advantages of hybrid development (i.e mixing SQL and NoSQL in the same database) is not just a marketing hype: it allowed us to solve with a brilliant solution, in one afternoon of coding, a functional problem we have been having for more than 10 years!
    • The biggest drawback is that IBM pricing may be constraining, it has too important gaps between the mid range and highrange in terms of pricing
