Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
SQLAlchemy's ORM and SQL toolkit features are extensive, requiring significant time to master.
ORM operations can introduce additional processing steps that slow down query execution times.
Configuring relationships, inheritance patterns, and custom mappers requires deep understanding of SQLAlchemy's internals.
The official documentation is comprehensive but lacks beginner-friendly tutorials and examples.
