Db2, an Enterprise-level Relational DB solution

It is best suited for scenarios where security cannot be compromised (such as, financial systems). This is something that Db2 caters for and why it was considered in our use case. Its recoverability capabilities are also important to note, again due to some systems requiring availability 24/7. In general though, it is an Enterprise solution, meaning that the licensing cost can be hard to shoulder for smaller companies, which coupled with the lack of trained engineers on it, make it less attractive to more mainstream solutions

We have particularly appreciated the integration with Apache Iceberg and with other, less refined, sources of data (such as CSV and exports from spreadsheets-management tools). For what concerns deployments, the focus was primarily for our financial systems and at that we were testing different options, so while it was clear that the capability is there, we could not take advantage of it fully

It's a bit difficult to evaluate this area as we did not encounter any issues while working with it, so in general I would say that Db2 was always available when we needed it; giving a higher rating without having faced any errors in this case would not reflect correctly our experience.
