Does SQLite support many to many?

What are the limitations of SQLite?

An SQLite database is limited in size to 281 terabytes (248 bytes, 256 tibibytes). And even if it could handle larger databases, SQLite stores the entire database in a single disk file and many filesystems limit the maximum size of files to something less than this.

How many tables can SQLite handle?

SQLite does not support joins containing more than 64 tables. This limit arises from the fact that the SQLite code generator uses bitmaps with one bit per join-table in the query optimizer. SQLite uses an efficient query planner algorithm and so even a large join can be prepared quickly.

Can SQLite handle multiple users?

Yes SQLite can support multiple users at once. It does however lock the whole database when writing, so if you have lots of concurrent writes it is not the database you want (usually the time the database is locked is a few milliseconds - so for most uses this does not matter).

Does SQLite support concurrency?

SQLite does support multiple concurrent connections, and therefore it can be used with a multi-threaded or multi-process application. The catch is that when SQLite opens a write transaction, it will lock all the tables.
