I thought there would be a higher profile announcement. I don't currently use Interbase, and kind of stumbled across this by accident, but it certainly caught my attention.
Some of my applications are stand alone or occasionally connected with their own local database storage. Situations where installing a separate database server would be overkill. When I can, I like using the same database for this everywhere. This means consistent features and SQL syntax, I can share common code and data I don't need separate data administration tools for different applications. Cost is also a consideration. I'm fine to pay for a good database, but I don't like license fees at the best of times, let alone for an embedded database.
There are any number of great solutions for this on Windows, and everyone has their favourites (I'm looking at you ElevateSoft), but there are fewer choices once you throw Mac and mobile into the mix.
I have been using SQLite and like it, but IBLite seems to be more robust with support for stored procedures and more complete SQL. I've also been bitten a couple of times by SQLite's dynamic column typing.
Either way, both databases are fully supported in Delphi Professional and higher on every platform that Delphi currently targets - Windows, OS X, iOS and Android.
I like having options.
