This is where Prisma 7 comes in. As an advanced ORM (Object-Relational Mapper) and database toolkit, Prisma 7 offers extended functionalities specifically designed to abstract and simplify the management and access to heterogeneous data sources, without sacrificing the specific advantages of individual databases.
