Use SQL (PostgreSQL, MySQL) for structured data needing ACID compliance. Use NoSQL (Cassandra, DynamoDB, MongoDB) for horizontal scalability and unstructured data 2.
: Define performance metrics explicitly. Quantify target availability (e.g., 99.99%), acceptable latency (e.g., p99 < 200ms), and data consistency boundaries (eventual vs. strong consistency). 2. Core API Definition & Data Modeling (5 Minutes)

Draw a bird's-eye view of the system. Outline the end-to-end flow of data without getting bogged down in implementation details. : Define performance metrics explicitly
Know when to use HTTP/HTTPS, WebSockets (for real-time), or TCP/UDP. 2. Key Components of System Architecture
Databases like PostgreSQL or MySQL excel at structured data, complex queries, and ACID compliance. Ideal for financial transactions or user profile management.
