Multiple, independent apps poking changes into the database is a kind of failure too. For writer apps > 1 it is often preferable to route them through a middle tier / web API / etc.

Data lives far, far longer than applications. You may not have multiple apps using the database now, but if your system lasts 10 years or more than it certainly will.

I think this approach creates bottlenecks and ultimately has an inner-platform effect.

Use your RDBMS to the max, they are powerful tools!
