What is Sqlite?
SQLite is an in-process library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. The code for SQLite is in the public domain and is thus free for use for any purpose, commercial or private.
SQLite is an embedded SQL database engine. Unlike most other SQL databases, SQLite does not have a separate server process. SQLite reads and writes directly to ordinary disk files.
A complete SQL database with multiple tables, indices, triggers, and views, is contained in a single disk file. The database file format is cross-platform - you can freely copy a database between 32-bit and 64-bit systems or between big-endian and little-endian architectures.
Features
Serverless
SQLite does not require a separate server process or system to operate. The SQLite library accesses its storage files directly.
Zero Configuration
No server means no setup. Creating an SQLite database instance is as easy as opening a file.
Cross-Platform
The entire database instance resides in a single cross-platform file, requiring no administration.
Self-Contained
A single library contains the entire database system, which integrates directly into a host application.
Small Runtime Footprint
The default build is less than a megabyte of code and requires only a few megabytes of memory. With some adjustments, both the library size and memory use can be significantly reduced.
Transactional
SQLite transactions are fully ACID-compliant, allowing safe access from multiple processes or threads.
Full-Featured
SQLite supports most of the query language features found in the SQL92 (SQL2) standard.
Highly Reliable
The SQLite development team takes code testing and verification very seriously.
Overall, SQLite provides a very functional and flexible relational database environment that consumes minimal resources and creates minimal hassle for developers and users.
