假設一個system同時用十幾個不同品牌的db, 仲要款款不同種類, 例如有oracle, 有mongodb, 有neo4j, 有cassandra
咁既情況你會唔會係db同app中間整多層layer, 統一個interface去access唔同既db?
定係會係program入面, 各自access自已需要既db?

it really doesn't matter as long as it is working and meet end user requirements. I will pick the one which requires less time to develop. Clients really dont care what is in the code

"Hybrid" database type is very common.
It is worth to build a Model layer (transparent API) to access different databases behind the scenes, then your program could be more decoupled.

ORM tools can take this job
e.g.: hibernate / entity framework
