==History==
[[D. Richard Hipp]] designed SQLite in the spring of 2000 while working for [[General Dynamics]] on contract with the [[United States Navy]].<ref name="Owens06">{{cite book |last=Owens |first=Michael |title=The Definitive Guide to SQLite |chapter=Introducing SQLite |year=2006 |publisher=[[Apress]] |isbn=978-1-59059-673-9 |doi=10.1007/978-1-4302-0172-4_1}}</ref> Hipp was designing software used for a [[Damage control (maritime)|damage-control]] system aboard [[guided-missile destroyer]]s; the damage-control system originally used [[HP-UX]] with an [[IBM Informix|Informix]] [[database]] back-end. SQLite began as a [[Tcl]] extension.<ref name=":0" />

In August 2000, version 1.0 of SQLite was released, with storage based on [[gdbm]] (GNU Database Manager). In September 2001, SQLite 2.0 replaced gdbm with a custom [[B-tree]] implementation, adding [[Database transaction|transaction]] capability. In June 2004, SQLite 3.0 added [[Internationalization and localization|internationalization]], [[manifest typing]], and other major improvements, partially funded by [[America Online]]. In 2011, Hipp announced his plans to add a [[NoSQL]] interface to SQLite, as well as announcing UnQL, a functional superset of [[SQL]] designed for [[document-oriented databases]].<ref name="unql-interview">{{cite web |url=http://www.infoq.com/news/2011/08/UnQL |title=Interview: Richard Hipp on UnQL, a New Query Language for Document Databases |publisher=InfoQ |date=August 4, 2011 |access-date=October 5, 2011 |archive-date=April 8, 2014 |archive-url=https://web.archive.org/web/20140408215240/http://www.infoq.com/news/2011/08/UnQL |url-status=live }}</ref>

In 2018, SQLite adopted a [[Code of conduct|Code of Conduct]] because some clients would not use the software without one.<ref>{{Cite web |last=Hipp |first=D. Richard |title=Code of Ethics |url=https://sqlite.org/codeofethics.html |access-date=January 24, 2025 |website=SQLite}}</ref> It was based on the [[Rule of Saint Benedict]] and was controversial for its religious nature. The document was later renamed as a Code of Ethics.<ref>{{Cite web |last=McCarthy |first=Kieren |title=SQLite creator crucified after code of conduct warns devs to love God, and not kill, commit adultery, steal, curse... |url=https://www.theregister.com/2018/10/22/sqlite_code_of_conduct/ |access-date=2022-11-17 |website=www.theregister.com |language=en |archive-date=2022-11-17 |archive-url=https://web.archive.org/web/20221117120853/https://www.theregister.com/2018/10/22/sqlite_code_of_conduct/ |url-status=live }}</ref>

SQLite is one of four formats recommended for long-term storage of [[Data set|datasets]] approved for use by the [[Library of Congress]].<ref>{{Cite web |url=https://sqlite.org/locrsf.html |title=LoC Recommended Storage Format |website=sqlite.org |access-date=2020-04-09 |archive-date=2020-04-23 |archive-url=https://web.archive.org/web/20200423212849/https://sqlite.org/locrsf.html |url-status=live }}</ref><ref>{{Cite web |url=https://www.loc.gov/preservation/digital/formats/fdd/fdd000461.shtml |title=SQLite, Version 3 |date=2017-03-28 |website=www.loc.gov |access-date=2020-04-09 |archive-date=2020-05-11 |archive-url=https://web.archive.org/web/20200511194518/https://www.loc.gov/preservation/digital/formats/fdd/fdd000461.shtml |url-status=live }}</ref><ref>{{Cite web |url=https://www.loc.gov/preservation/resources/rfs/data.html |title=Recommended Formats Statement – datasets/databases |publisher=Library of Congress |access-date=2020-04-09 |archive-date=2018-08-22 |archive-url=https://web.archive.org/web/20180822113435/https://www.loc.gov/preservation/resources/rfs/data.html |url-status=live }}</ref>

==Design==
SQLite was designed to allow the program to be operated without installing a database management system or requiring a [[database administrator]]. Unlike [[Client–server model|client–server]] database management systems, the SQLite engine has no standalone [[process (computing)|process]]es with which the application program communicates. Instead, a [[Linker (computing)|linker]] integrates the SQLite library{{emdash}}[[static library|statically]] or [[dynamic linker|dynamically]]{{emdash}}into an application program which uses SQLite's functionality through simple [[subroutine|function calls]], reducing [[latency (engineering)|latency]] in database operations; for simple queries with little concurrency, SQLite [[Computer performance|performance]] profits from avoiding the overhead of [[inter-process communication]].

Due to the serverless design, SQLite applications require less configuration than client–server databases. SQLite is called ''zero-configuration''<ref>{{cite web |title = SQLite Is A Zero-Configuration Database |url = https://sqlite.org/zeroconf.html |access-date = August 3, 2015 |publisher = SQLite.org |archive-date = May 2, 2024 |archive-url = https://web.archive.org/web/20240502210736/https://sqlite.org/zeroconf.html |url-status = live }}</ref> because configuration tasks such as service management, startup scripts, and password- or [[Data control language|GRANT]]-based access control are unnecessary. [[Access-control list|Access control]] is handled through the [[file-system permissions]] of the database file.<ref name=":2">{{Cite web |title=SQLite |url=https://clickhouse.com/docs/en/engines/database-engines/sqlite |access-date=January 25, 2025 |website=ClickHouse Docs}}</ref> Databases in client–server systems use [[File system|file-system]] permissions that give access to the database files only to the [[Daemon (computing)|daemon]] process, which handles its locks internally, allowing [[Concurrency (computer science)|concurrent]] writes from several processes.

SQLite stores the entire database, consisting of definitions, [[Table (database)|tables]], indices, and data, as a single [[Cross-platform software|cross-platform]] file, allowing several processes or [[thread (computer science)|threads]] to access the same database concurrently. It implements this simple design by [[lock (computer science)|locking]] the database file during writing.<ref name=":2" /> Write access may fail with an [[error code]], or it can be retried until a configurable timeout expires. SQLite read operations can be [[Computer multitasking|multitasked]], though due to the serverless design, writes can only be performed sequentially. This concurrent access restriction does not apply to temporary tables, and it is relaxed in version 3.7 as [[write-ahead logging]] (WAL) enables concurrent reads and writes.<ref>{{cite web |url = https://sqlite.org/wal.html |title = Write Ahead Logging in SQLite 3.7 |publisher = SQLite.org |access-date = September 3, 2011 |quote = WAL provides more concurrency as readers do not block writers and a writer does not block readers. Reading and writing can proceed concurrently. |archive-date = May 2, 2024 |archive-url = https://web.archive.org/web/20240502210711/https://sqlite.org/wal.html |url-status = live }}</ref> Since SQLite has to rely on file-system locks, it is not the preferred choice for write-intensive deployments.<ref>{{cite web |title = Appropriate Uses For SQLite |url = https://sqlite.org/whentouse.html |access-date = 2015-09-03 |publisher = SQLite.org |archive-date = 2024-05-02 |archive-url = https://web.archive.org/web/20240502210713/https://sqlite.org/whentouse.html |url-status = live }}</ref>

SQLite uses [[PostgreSQL]] as a reference platform. "What would PostgreSQL do" is used to make sense of the SQL standard.<ref>{{cite web |url=https://lwn.net/Articles/601144/ |title=PGCon 2014: Clustering and VODKA |website=Lwn.net |access-date=2017-01-06 |archive-date=2015-06-29 |archive-url=https://web.archive.org/web/20150629195442/https://lwn.net/Articles/601144/ |url-status=live }}</ref><ref>{{cite web |url=https://www.pgcon.org/2014/schedule/events/736.en.html |title=PGCon2014: SQLite: Protégé of PostgreSQL |website=Pgcon.org |date=20 September 2015 |access-date=2017-01-06 |archive-date=2014-12-30 |archive-url=https://web.archive.org/web/20141230193958/http://www.pgcon.org/2014/schedule/events/736.en.html |url-status=live }}</ref> One major deviation is that, with the exception of [[primary key]]s, SQLite does not enforce [[type checking]]; the type of a value is dynamic and not strictly constrained by the [[database schema|schema]] (although the schema will trigger a conversion when storing, if such a conversion is potentially reversible). SQLite strives to follow [[Robustness principle|Postel's rule]].<ref name=":1">{{cite web |title=SQLite: StrictMode |url=https://sqlite.org/src/wiki?name=StrictMode |url-status=live |archive-url=https://web.archive.org/web/20160304115940/https://sqlite.org/src/wiki?name=StrictMode |archive-date=March 4, 2016 |access-date=September 3, 2015 |website=Sqlite.org}}</ref>

==Features==
SQLite implements most of the [[SQL-92]] standard for SQL, but lacks some features. For example, it only partially provides [[database trigger|triggers]] and cannot write to [[view (database)|views]] (however, it provides INSTEAD OF triggers that provide this functionality). Its support of [[Data definition language#ALTER statement|ALTER TABLE]] statements is limited.<ref>{{Cite web|url=https://sqlite.org/changes.html|title=Release History of SQLite|access-date=2021-03-22|archive-date=2021-03-16|archive-url=https://web.archive.org/web/20210316043517/https://sqlite.org/changes.html|url-status=live}}</ref>

SQLite uses an unusual [[type system]] for an SQL-compatible DBMS: instead of assigning a [[SQL data types|type]] to a column as in most SQL database systems, types are assigned to individual values; in language terms it is ''dynamically typed''. Moreover, it is ''weakly typed'' in some of the same ways that [[Perl]] is: one can insert a [[string (computer science)|string]] into an [[Integer (computer science)|integer]] column (although SQLite will try to convert the string to an integer first, if the column's preferred type is integer). This adds flexibility to columns, especially when bound to a dynamically typed scripting language. However, the technique is not portable to other SQL products. A common criticism is that SQLite's type system lacks the [[data integrity]] mechanism provided by statically typed columns, although it can be emulated with constraints like {{code|2=sql|1=CHECK(typeof(x)='integer')}}.<ref name="Owens06" /> In 2021, support for static typing was added through STRICT tables, which enforce datatype constraints for columns.<ref>{{Cite web |title=STRICT Tables |url=https://sqlite.org/stricttables.html |access-date=January 24, 2025 |website=SQLite}}</ref>

Tables normally include a hidden ''rowid'' index column, which provides faster access.<ref>{{cite web |title=SQL As Understood By SQLite |url=https://sqlite.org/lang_createtable.html#rowid |website=SQLite |access-date=21 May 2018 |quote=Searching for a record with a specific rowid, or for all records with rowids within a specified range is around twice as fast as a similar search made by specifying any other PRIMARY KEY or indexed value. |archive-date=21 May 2018 |archive-url=https://web.archive.org/web/20180521104530/https://sqlite.org/lang_createtable.html#rowid |url-status=live }}</ref> If a table includes an INTEGER PRIMARY KEY column, SQLite will typically optimize it by treating it as an alias for the ''rowid'', causing the contents to be stored as a [[strictly typed]] 64-bit signed integer and changing its behavior to be somewhat like an auto-incrementing column. SQLite includes an option to create a table without a rowid column, which can save disk space and improve lookup speed. WITHOUT ROWID tables are required to have a primary key.<ref>{{Cite web |title=Clustered Indexes and the WITHOUT ROWID Optimization |url=https://sqlite.org/withoutrowid.html |access-date=January 24, 2025 |website=SQLite}}</ref>

SQLite supports foreign key constraints,<ref>{{cite book |last=Karwin |first=Bill |editor-last=Carter |editor-first=Jacquelyn |date=May 2010 |title=SQL Antipatterns: Avoiding the Pitfalls of Database Programming |publisher=The Pragmatic Bookshelf |isbn=978-1-934356-55-5 |page=70 |quote=Sometimes you're forced to use a database brand that doesn't support foreign key constraints (for example MySQL's MyISAM storage engine or SQLite prior to version 3.6.19).}}</ref><ref>{{Cite web|url=https://sqlite.org/releaselog/3_6_19.html|title=SQLite Release 3.6.19 On 2009-10-14|website=sqlite.org|access-date=2020-10-15|archive-date=2020-10-29|archive-url=https://web.archive.org/web/20201029060401/http://sqlite.org/releaselog/3_6_19.html|url-status=live}}</ref> although they are disabled by default and must be manually enabled with a PRAGMA statement.<ref>{{Cite web |title=SQLite Foreign Key Support |url=https://sqlite.org/foreignkeys.html |access-date=January 24, 2025 |website=SQLite}}</ref>

[[Stored procedure]]s are not supported; this is an explicit choice by the developers to favor simplicity, as the typical use case of SQLite is to be embedded inside a host application that can define its own procedures around the database.<ref>Source: developers' comments on [https://sqlite.org/forum/info/78a60bdeec7c1ee9 SQLite forum] {{Webarchive|url=https://web.archive.org/web/20230401220416/https://sqlite.org/forum/info/78a60bdeec7c1ee9 |date=2023-04-01 }}</ref>

SQLite does not have full [[Unicode]] support by default for backwards compatibility and due to the size of the Unicode tables, which are larger than the SQLite library.<ref>{{Cite web |title=Quirks, Caveats, and Gotchas In SQLite |url=https://sqlite.org/quirks.html |access-date=January 24, 2025 |website=SQLite}}</ref> Full support for [[Unicode]] case-conversions can be enabled through an optional extension.<ref>{{cite web |title = Case-insensitive matching of Unicode characters does not work |url = https://sqlite.org/faq.html#q18 |website = SQLite Frequently Asked Questions |access-date = 2015-09-03 |archive-date = 2015-09-05 |archive-url = https://web.archive.org/web/20150905054749/https://sqlite.org/faq.html#q18 |url-status = live }}</ref>

SQLite supports [[full-text search]] through its FTS5 loadable extension, which allows users to efficiently search for a keyword in a large number of documents similar to how [[search engine]]s search webpages.<ref>{{Cite web |title=SQLite FTS5 Extension |url=https://sqlite.org/fts5.html |access-date=January 24, 2025 |website=SQLite}}</ref>

SQLite includes support for working with [[JSON]] through its ''json1'' extension, which is enabled by default since 2021. SQLite's JSON functions can handle JSON5 syntax since 2023. In 2024, SQLite added support for JSONB, a binary serialization of SQLite's internal representation of JSON. Using JSONB allows applications to avoid having to parse the JSON text each time it is processed and saves a small amount of disk space.<ref>{{Cite web |title=JSON Functions And Operators |url=https://sqlite.org/json1.html |access-date=January 24, 2025 |website=SQLite}}</ref>

The maximum supported size for an SQLite database file is 281 terabytes.<ref>{{cite web|url=https://sqlite.org/limits.html|title=Limits In SQLite|website=SQLite.org|access-date=2022-09-19|archive-date=2021-11-07|archive-url=https://web.archive.org/web/20211107064937/https://sqlite.org/limits.html|url-status=live}}</ref>

==Development and distribution==
SQLite's code is hosted with [[Fossil (software)|Fossil]], a [[distributed version control system]] that uses SQLite as a local cache for its non-relational database format, and SQLite's SQL as an implementation language.<ref>{{cite web|url = https://www.fossil-scm.org/home/doc/trunk/www/theory1.wiki|title = Thoughts On The Design Of The Fossil DVCS|publisher = Fossil-scm.org|date = July 12, 2017|access-date = October 14, 2022|archive-date = October 13, 2022|archive-url = https://web.archive.org/web/20221013234319/https://www.fossil-scm.org/home/doc/trunk/www/theory1.wiki|url-status = live}}</ref><ref>{{cite web|url = https://www.fossil-scm.org/index.html/doc/tip/www/stats.wiki|title = Fossil: Fossil Performance|publisher = Fossil-scm.org|date = August 23, 2009|access-date = September 12, 2009|archive-date = October 9, 2009|archive-url = https://web.archive.org/web/20091009054952/http://www.fossil-scm.org/index.html/doc/tip/www/stats.wiki|url-status = live}}</ref>

A standalone [[Console application|command-line]] [[Shell (computing)|shell]] program called ''sqlite3''<ref>{{cite web|url = https://sqlite.org/cli.html|title = Command Line Shell For SQLite|publisher = Sqlite.org|access-date = October 14, 2022|archive-date = October 6, 2022|archive-url = https://web.archive.org/web/20221006104551/https://sqlite.org/cli.html|url-status = live}}</ref> is provided in SQLite's distribution. It can be used to create a database, define tables, insert and change rows, run queries and manage an SQLite database file. It also serves as an example for writing applications that use the SQLite library.

SQLite uses automated [[regression testing]] prior to each release. Over 2 million tests are run as part of a release's verification. The SQLite library has 156,000 lines of source code, while all the test suites combined add up to 92 million lines of test code. SQLite's tests simulate a number of exceptional scenarios, such as power loss and I/O errors, in addition to testing the library's functionality. Starting with the August 10, 2009 release of SQLite 3.6.17, SQLite releases have 100% branch test coverage, one of the components of [[code coverage]]. SQLite has four different [[Test harness|test harnesses]]: the original public-domain TCL tests, the proprietary C-language TH3 test suite, the SQL Logic Tests, which check SQLite against other SQL databases, and the dbsqlfuzz proprietary [[fuzzing]] engine.<ref name="tests">{{cite web |title=How SQLite Is Tested |url=https://sqlite.org/testing.html |url-status=live |archive-url=https://web.archive.org/web/20091006224147/https://sqlite.org/testing.html |archive-date=October 6, 2009 |access-date=September 12, 2009 |publisher=SQLite.org}}</ref>

* [[Component Object Model|COM]] ([[ActiveX]]) wrapper making SQLite accessible on Windows to scripted languages such as [[JScript]] and [[VBScript]]. This adds SQLite database capabilities to [[HTML Application]]s (HTA).<ref>{{cite web|url = https://sqlite.org/cvstrac/wiki?p=SqliteWrappers|title = sqlite&nbsp;— Sqlite Wrappers|date = February 7, 2009|publisher = SQLite.org|access-date = February 7, 2009|archive-date = February 5, 2009|archive-url = https://web.archive.org/web/20090205225756/http://sqlite.org/cvstrac/wiki?p=SqliteWrappers|url-status = live}}</ref>

===Web browsers===
* The browsers [[Google Chrome]], [[Opera (web browser)|Opera]], [[Safari (web browser)|Safari]] and the [[Android Browser]] all allow for storing information in, and retrieving it from, an SQLite database within the browser, using the official SQLite Wasm ([[WebAssembly]]) build,<ref>{{Cite web

}}</ref> or using the [[Web SQL Database]] technology, although the latter is becoming deprecated (namely superseded by SQLite Wasm or by [[IndexedDB]]). Internally, these [[Chromium (web browser)|Chromium]] based browsers use SQLite databases for storing configuration data like site visit history, cookies, download history etc.<ref>{{cite web |url=https://www.foxtonforensics.com/browser-history-examiner/chrome-history-location |title=Location of Google Chrome history |website=www.foxtonforensics.com |date=2020-10-06 |access-date=2020-10-06 |archive-date=2023-02-28 |archive-url=https://web.archive.org/web/20230228184524/https://www.foxtonforensics.com/browser-history-examiner/chrome-history-location |url-status=live }}</ref>
* [[Mozilla Firefox]] and [[Mozilla Thunderbird]] store a variety of configuration data (bookmarks, cookies, contacts etc.) in internally managed SQLite databases. Until Firefox version 57 ([[History of Firefox#Firefox 57|"Firefox Quantum"]]), there was a third-party add-on that used the API supporting this functionality to provide a user interface for managing arbitrary SQLite databases.<ref>{{cite web|url=https://addons.mozilla.org/en-US/firefox/addon/sqlite-manager/ |title=SQLite Manager :: Add-ons for Firefox |website=Addons.mozilla.org |date=2015-02-28 |access-date=2017-01-06 |url-status=dead |archive-url=https://web.archive.org/web/20170102010658/https://addons.mozilla.org/en-US/firefox/addon/sqlite-manager/ |archive-date=2017-01-02}}</ref>
