How does LINQ influence system design decisions in large-scale architectures?

LINQ influences abstraction boundaries, data access design, and performance trade-offs in large systems.

In large-scale architectures, LINQ shapes how data access layers are designed. It promotes repository patterns and abstraction over raw SQL. However, it can also blur boundaries if IQueryable leaks into upper layers. Architects must balance LINQ convenience with control over query execution, performance tuning, and observability.
