SQLite began as a [[Tcl]] extension. [54] => [55] => 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]].{{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}} In 2018, SQLite adopted a Code of Conduct based on the [[Rule of Saint Benedict]] which caused some controversy and was later renamed as a Code of Ethics.{{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}} [56] => [57] => SQLite is one of four formats recommended for long-term storage of [[Data set|datasets]] approved for use by the [[Library of Congress]].{{Cite web |url=https://www.sqlite.org/locrsf.html |title=LoC Recommended Storage Format |website=www.sqlite.org |access-date=2020-04-09}}{{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}}{{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}} [58] => [59] => ==Design== [60] => 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]]. [61] => [62] => Due to the serverless design, SQLite applications require less configuration than client–server databases. SQLite is called ''zero-conf''{{cite web |title = SQLite Is A Zero-Configuration Database |url = https://sqlite.org/zeroconf.html |access-date = August 3, 2015 |publisher = SQLite.org}} because it does not require service management (such as startup scripts) or access control based on [[Data control language|GRANT]] and passwords. [[Access-control list|Access control]] is handled by means of [[file-system permissions]] given to the database file itself. 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. [63] => [64] => SQLite stores the whole database (definitions, [[Table (database)|tables]], indices, and the data itself) as a single [[Cross-platform software|cross-platform]] file on a host machine, 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. 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.{{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.}} Since SQLite has to rely on file-system locks, it is not the preferred choice for write-intensive deployments.{{cite web |title = Appropriate Uses For SQLite |url = https://sqlite.org/whentouse.html |access-date = 2015-09-03 |publisher = SQLite.org}} [65] => [66] => SQLite uses [[PostgreSQL]] as a reference platform. "What would PostgreSQL do" is used to make sense of the SQL standard.{{cite web |url=https://lwn.net/Articles/601144/ |title=PGCon 2014: Clustering and VODKA |website=Lwn.net |access-date=2017-01-06}}{{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}} 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]]. [67] => [68] => ==Features== [69] => 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.{{Cite web|url=https://www.sqlite.org/changes.html|title = Release History of SQLite}} [70] => [71] => 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')}}. Strict tables were added in version 3.37.1.{{cite web |title = SQLite: StrictMode |url = https://sqlite.org/src/wiki?name=StrictMode |website=Sqlite.org |access-date = September 3, 2015}} [72] => [73] => Tables normally include a hidden ''rowid'' index column, which gives faster access.{{cite web |title=SQL As Understood By SQLite |url=https://www.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.}} If a database includes an Integer Primary Key column, SQLite will typically optimize it by treating it as an alias for ''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. Future{{when|date=August 2019}} versions of SQLite may include a command to introspect whether a column has behavior like that of ''rowid'' to differentiate these columns from weakly typed, non-autoincrementing Integer Primary Keys.{{cite web |url=https://www.sqlite.org/src/info/2494132a2b1221a4 |title=SQLite: Check-in [2494132a] |quote=Add the "PRAGMA table_ipk(TABLE)" command for evaluation purposes. |website=www.sqlite.org |date=2017-11-28}}{{failed verification|date=August 2019}} [74] => [75] => Version 3.6.19 released on October 14, 2009 added support for foreign key constraints.{{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).}}{{Cite web|url=https://sqlite.org/releaselog/3_6_19.html|title=SQLite Release 3.6.19 On 2009-10-14|website=sqlite.org}} [76] => [77] => [[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.Source: developers' comments on [https://sqlite.org/forum/info/78a60bdeec7c1ee9 SQLite forum] [78] => [79] => Full support for [[Unicode]] case-conversions can be enabled through an optional extension.{{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}} [80] => [81] => SQLite version 3.7.4 first saw the addition of the FTS4 ([[full-text search]]) module, which features enhancements over the older FTS3 module.{{cite web |title = SQLite Release 3.7.4 On 2010-12-08 |url = https://sqlite.org/releaselog/3_7_4.html |access-date = September 3, 2015 |date = December 8, 2010 |publisher = SQLite.org}} FTS4 allows users to perform full-text searches on documents similar to how [[Search engine|search engines]] search webpages.{{cite web |title = SQLite FTS3 and FTS4 Extensions |url = https://sqlite.org/fts3.html |access-date = September 3, 2015 |publisher = SQLite.org}} Version 3.8.2 added support for creating tables without [[Pseudocolumn|rowid]],{{cite web |title = SQLite Release 3.8.2 On 2013-12-06 |url = https://sqlite.org/releaselog/3_8_2.html |access-date = September 3, 2015 |date = December 6, 2013 |publisher = SQLite.org}} which may provide space and performance improvements.{{cite web |title = The WITHOUT ROWID Optimization |url = https://sqlite.org/withoutrowid.html |access-date = September 3, 2015 |publisher = SQLite.org}} [[Common table expressions]] support was added to SQLite in version 3.8.3.{{cite web |title = SQLite Release 3.8.3 On 2014-02-03 |url = https://sqlite.org/releaselog/3_8_3.html |access-date = September 3, 2015 |date = February 3, 2014 |publisher = SQLite.org}} 3.8.11 added a newer search module called FTS5, the more radical (compared to FTS4) changes requiring a bump in version.

More about us

About

It is embedded into many popular applications and is sometimes referred to as an "embedded database. " SQLite is self-contained, serverless, and does not require a separate database server process to operate. It is present on a wide range of computing platforms, including Windows, macOS, iOS, Android, and Linux. SQLite follows a transactional and ACID-compliant design and supports SQL queries and database triggers. It is licensed as public domain software, allowing its use in both proprietary and open-source applications. SQLite is known for its small footprint, efficiency, and stability, making it a popular choice for small to medium-sized projects, as well as mobile and embedded systems.
