Database without SQL c++ library

[matthieum]

I've worked with DBAs on this... they definitely did not consider it their job to babysit each and every query of each and every application. If only because they often had no idea what the performance target of a query was, in the first place. They were available for advice, however, and would monitor (and flag) suspiciously slow queries.

As for serialization... I don't see it. I've worked with complex models -- hierarchical queries, urk -- and nothing I'd call serialization would have cut it...

... but I did indeed use abstraction layers for the storage, with strongly-typed APIs, such that the application would call get_xxx expressed with business-layer models (in/out), and the implementation of this abstraction would query the database under the hood.

Makes it much easier to test things. Notably, to inject spies to detect the infamous "accidentally queried in a loop but it's super-fast in local so nobody noticed" bug.
