Everything you need to know about storing, querying, scaling, and managing your data — across SQL, NoSQL, and beyond.
This category is for anyone working with SQL, from writing basic SELECT queries to joining tables, optimizing performance, or debugging strange results.
Unlike backend or data-related categories, this one focuses purely on working with relational databases and SQL syntax, no programming logic or frameworks, just the data layer.
Topics can include query help, database design, joins, indexing, performance tuning, migrations, and SQL-specific questions across MySQL, PostgreSQL, SQLite, and others.
