Nevertheless, performance is usually quite good even in low-memory environments. In this SQLite with Swift tutorial, you’ll learn how to perform the following database operations: Create and connect to a database. SQLite generally runs faster the more memory you give it. There is a tradeoff between memory usage and speed. SQLite can also be made to run in minimal stack space (4KiB) and very little heap (100KiB), making SQLite a popular database engine choice on memory constrained gadgets such as cellphones, PDAs, and MP3 players. (Some compiler optimizations such as aggressive function inlining and loop unrolling can cause the object code to be much larger.) If optional features are omitted, the size of the SQLite library can be reduced below 180KiB. Reference describes the classes and functions this module defines.
Tutorial teaches how to use the sqlite3 module. It provides an SQL interface compliant with the DB-API 2.0 specification described by PEP 249, and requires SQLite 3.7.15 or newer. With all features enabled, the library size can be less than 300KiB, depending on compiler optimization settings. The sqlite3 module was written by Gerhard Hring.

Think of SQLite not as a replacement for Oracle but as a replacement for fopen() If you need a GUI for database management, you can install NAVICAT. These features make SQLite a popular choice as an Application File Format. Proceed to the next (third) window area and choose the operating system bottle. 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. Highlight the installer and click on ‘Use this installer’.
A complete SQL database with multiple tables, indices, triggers, and views, is contained in a single disk file. SQLite reads and writes directly to ordinary disk files. Unlike most other SQL databases, SQLite does not have a separate server process. SQLite is an embedded SQL database engine. SQLite is currently found in more applications than we can count, including several high-profile projects. The code for SQLite is in the public domain and is thus free for use for any purpose, commercial or private. SQLite is an in-process library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine.
