SQLite

Tək faylda tam verilənlər bazası.

SQLite is a complete SQL database in a single file. There is no server to install: the engine is a small library inside the app, which is why it runs on every Android phone and iPhone, in every major web browser and in countless apps. You already know SQL from the SQL track, so this course is about what makes SQLite different: the sqlite3 shell, flexible types and STRICT tables, safe access from Python, transactions and WAL mode, indexes and query plans, JSON, and foreign keys.

Every query and program in this track was really run, and every result you see is exactly what it printed.
