> Any situation where complex functionality is wrapped in another layer runs the risk of increasing the overall complexity when the wrapping layer is itself complicated. This often comes along with leaky abstractions - wherin the wrapping layer can't do a perfect job wrapping the underlying functionality, and forces programmers to fight with both layers simultaneously.
I think we can all agree that a mapping layer from a relational DB to your language is needed in almost every application, so the question is whether to build it yourself or use an off-the-shelf solution.
I work at prisma.io and we've set out to make database workflows as easy as possible for developers, this includes database access (= ORM) and schema migrations.
With polyglot persistence becoming a standard pattern in modern applications, today's ORMs fall short since they only map from relational databases. Our goal at Prisma is to provide a type-safe mapping layer to all your databases at once. This will allow developers to focus on their application logic and not worry about how to access the data from the various data sources.
