What is schema in SQLite?

Every SQLite database contains a single "schema table" that stores the schema for that database. The schema for a database is a description of all of the other tables, indexes, triggers, and views that are contained within the database.

What are the data types in SQLite?

SQLite only has four primitive data types: INTEGER, REAL, TEXT, and BLOB. APIs that return database values as an object will only ever return one of these four types. Additional . NET types are supported by Microsoft.

What is SQLite index?

Advertisements. Indexes are special lookup tables that the database search engine can use to speed up data retrieval. Simply put, an index is a pointer to data in a table. An index in a database is very similar to an index in the back of a book.

How is SQLite data stored?

The complete state of an SQLite database is usually contained in a single file on disk called the "main database file". During a transaction, SQLite stores additional information in a second file called the "rollback journal", or if SQLite is in WAL mode, a write-ahead log file.
