SQLite is contained in a C programming library. SQLite is cross platform and portable and runs amazingly in all types of devices, from servers, to desktops and especially in mobile devices.This is because in contrast to many other database management systems, it is not a client–server database engine. Rather, it is embedded into the end program.
SQLite is ACID-compliant and implements most of the SQL standard, using a dynamically and weakly typed SQL syntax that does not guarantee the domain integrity.
ACID in full is Atomicity, Consistency, Isolation, Durability.These are properties of database transactions intended to guarantee validity even in the event of errors, power failures, etc. In the context of databases, a sequence of database operations that satisfies the ACID properties is called a transaction.
SQLite is used in:
It also has bindings to many programming languages like Java, C#, PHP, Python etc.
