SQL vs. NoSQL Databases The choice between SQL and NoSQL impacts how your application stores, scales, and manages data. SQL (Relational Databases) SQL databases use a structured, table-based format with rows and columns. They rely on a predefined schema, meaning you must define the data structure before adding any information. Strengths: Excellent for complex queries, multi-row transactions, and maintaining strict data integrity (ACID compliance). Best Use: Financial systems, accounting software

Дашборд тормозит 5 секунд на каждой загрузке из-за тяжёлой агрегации? В Postgres это чинится одной командой — без Redis. VIEW не спасёт: это просто сохранённый текст запроса, агрегация гоняется заново каждый раз. А MATERIALIZED VIEW хранит готовый результат на диске — любой SELECT отдаёт его за ~50 мс вместо 5 секунд. В 100 раз быстрее. Нюанс: сам не обновляется — нужен REFRESH (обычно по расписанию). Зато, в отличие от Redis, его можно индексировать, фильтровать в SELECT и джойнить как обычную
