It is actively +tested on all currently popular CPUs and operating +systems. +The extreme portability of the SQLite code and file +format will help it remain viable on future platforms. + +</p></li><li><p> +<b>Stable, Cross-platform Database Files</b> → +SQLite <a href="fileformat2.html">database files</a> are bit-for-bit identical on +32-bit, 64-bit, big-endian, and little-endian platforms. You +can copy an SQLite database file from one system to another +without having to translate or convert the database. +Furthermore, the file format is well documented and stable. +Database files created today will be readable and writable by +future versions of SQLite decades in the future. + +</p></li><li><p> +<b><a href="testing.html">Aviation-grade testing</a></b> → +Every machine-code branch instruction is tested in both +directions. Multiple times. On multiple platforms and with +multiple compilers. This helps make the code robust for +future migrations. The intense testing also means that new +developers can make experimental enhancements to SQLite and, +assuming legacy tests all pass, be reasonably sure that the +enhancement does not break legacy. + +</p></li><li><p> +<b>Extensive, detailed documentation</b> → +SQLite has candid, developer-friendly, +and open-source documentation. Docs are written by and +for programmers. +(A few examples: +<a href="./arch.html">[1]</a> +<a href="./fileformat.html">[2]</a> +<a href="./queryplanner.html">[3]</a> +<a href="./opcode.html">[4]</a> +<a href="./compile.html">[5]</a> +<a href="./malloc.html">[6]</a> +<a href="./debugging.html">[7]</a> +<a href="./howtocorrupt.html">[8]</a>) +The extensive documentation helps new developers +come up to speed on SQLite very quickly. + +</p></li><li><p> +<b>Heavily commented source code</b> → +The SQLite source code is over 35% comment. Not boiler-plate +comments, but useful comments that explain the meaning of variables +and objects and the intent of methods and procedures. +The code is designed +to be accessible to new programmers and maintainable over a span +of decades. + +</p></li><li><p> +<b>Disaster planning</b> → +Every byte of source-code history for SQLite is cryptographically +protected and is automatically replicated to multiple +geographically separated servers, in datacenters +owned by different companies. +Thousands of additional clones exist on private servers around the +world. +The primary developers of SQLite live in different regions of the world. +SQLite can survive a continental catastrophe. + +</p></li><li><p> +<b>Old school</b> → +Nobody is completely immune to trends and fads, but the SQLite +developers work hard to avoid being sucked into the latest programming +fashion. Our aim is to produce timeless code that will be +readable, understandable, and maintainable by programmers +who have not yet been born. +</p></li></ul> + +<p> +In addition to "supporting" SQLite through the year 2050, the developers +also promise to keep the SQLite +<a href="cintro.html">C-language API</a> and <a href="fileformat2.html">on-disk format</a> +fully backwards compatible. +This means that application written to use SQLite today should be able to +link against and use future versions of SQLite released decades in the +future. + +</p><p> +Our goal is to make the content you store in SQLite today as +easily accessible to your grandchildren as it is to you. + +</p><p> +<b>Update on 2018-05-31:</b> +Our goal of supporting SQLite long-term have apparently come to the +notice of the preservationist at the +<a href="https://www.loc.gov">US Library Of Congress</a> who have identified +SQLite as a <a href="locrsf.html">recommended storage format</a> for the preservation of +digital content. +</p><p align="center"><small><i>This page last modified on <a href="https://sqlite.org/docsrc/honeypot" id="mtimelink" data-href="https://sqlite.org/docsrc/finfo/pages/lts.in?m=c7fb3381bb">2022-01-08 05:02:57</a> UTC </small></i></p> + |
