Offers flexible schemas (document, key-value, graph, wide-column) optimized for high write speeds and horizontal scaling. Database Indexing
Backend engineers must know how to store and fetch data efficiently. Relational Databases (SQL) PostgreSQL, MySQL.

Databases like MongoDB (document-based), Cassandra (wide-column), or Neo4j (graph) offer flexible schemas. They scale horizontally more easily than SQL databases and are optimized for specific data structures and high-speed write operations. Indexing and Query Optimization
Fundamentals of Backend Communications and Protocols (course) gRPC The server processes client requests
The Open Systems Interconnection (OSI) model standardizes network functions. Backend engineers primarily work with the Transport Layer (Layer 4) and the Application Layer (Layer 7). Layer 4 handles protocols like TCP and UDP, focusing on packet delivery. Layer 7 handles protocols like HTTP and MQTT, focusing on data formatting and user interaction. REST vs. GraphQL vs. gRPC
The server processes client requests, executes business logic, and interacts with databases. executes business logic
: Vertical scaling adds power (CPU, RAM) to an existing server. Horizontal scaling adds more servers to the pool.
