SQLite: The in-process SQL engine that ships in every phone, browser and OS: one file, zero servers. ZODB: Transparent persistence for Python objects with ACID transactions and history.

key differences

  • SQLite is primarily a relational database; ZODB is object.
  • Only SQLite has joins, secondary indexes, full-text search, json, triggers.
  • Only ZODB has time travel, online schema changes.
