Data Layer vs Direct Database Access

Developers should implement a Data Layer when building applications that require clean separation of concerns, such as web apps, mobile apps, or enterprise systems, to manage data persistence and business rules independently from UI logic meets developers should use direct database access when they need maximum performance, such as in high-throughput systems like financial trading platforms or real-time analytics, where orm overhead is unacceptable. Here's our take.
