Sep 20, 2021 · SQLite databases store data in tables, which may contain multiple fields of various data types such as text or integers. Developers can access and modify this data using SQL queries or "CRUD" (create, read, update, delete) operations. Since databases are self-contained, updates to the database are fully contained within the SQLITE file. SQLite is a server-less database and is self-contained. This is also referred to as an embedded database which means the DB engine runs as a part of the app. On the other hand, MySQL requires a server to run. MySQL will require a client and server architecture to interact over a network. Data Type Support - SQLite vs MySQLWhat Is Core Data.
