What is the difference between SQLite and Express SQL?

SQLite is a lightweight, autonomous, serverless, self-contained transactional database. Data is stored in a single file.

SQL Server Express is a free edition of Microsoft SQL Server. It is a server-based database requiring installation and server management.
