wxSQLite3 is a C++ wrapper around the public domain SQLite 3.x database and is specifically designed for use in programs based on the wxWidgets library.
wxSQLite3 does not try to hide the underlying database, in contrary almost all special features of the current SQLite version 3.53.4 are supported, like for example the creation of user defined scalar or aggregate functions. Since SQLite stores strings in UTF-8 encoding, the wxSQLite3 methods provide automatic conversion between wxStrings and UTF-8 strings. This works best for the Unicode builds of wxWidgets. In ANSI builds the current locale conversion object (wxConvCurrent) is used for conversion to/from UTF-8. Special care has to be taken if external administration tools are used to modify the database contents, since not all of these tools operate in Unicode resp. UTF-8 mode.
Since version 1.7.0 optional support for key based database encryption (128-bit AES) is included. Starting with version 1.9.6 of wxSQLite3 the encryption extension is compatible with the SQLite amalgamation source and includes the extension functions module. Support for 256-bit AES encryption has been added in version 1.9.8.
Since version 3.5.0 the SQLite library is an integrated part of wxSQLite3.
Since version 4.0.0 wxSQLite3 supports to select the encryption scheme at runtime. Currently, 7 different cipher schemes can be selected:
Since version 4.6.0 wxSQLite3 uses a separate implementation of the encryption extension, namely SQLite3 Multiple Ciphers, because the formerly used SQLITE_HAS_CODEC interface was removed from SQLite in February 2020.
wxSQLite3 5.x (first released in August 2026) is a major update with a modernized C++ API. It is not fully source-compatible with wxSQLite3 4.x. Therefore, wxSQLite3 4.x will receive maintenance updates, including updates to the bundled SQLite version, for a limited period following the release of 5.0.0. No new API features will be added. The End-of-Life date of version 4.x will be announced separately.
The wxSQLite3 API has been extended with several features aimed at modern C++ development:
These features complement the existing wxSQLite3 API and allow result-set and prepared-statement code to be written in a more concise and type-oriented style.

phpSQLiteAdmin is a name of two independent web applications, written in PHP, for managing SQLite databases. phpSQLiteAdmin is a web-based client which leverages PHP scripting and the SQLite file-database system to provide a simple way for users to create databases, create tables, and query their own data using non-industry-standard SQLite syntax. By now they seem like two abandoned projects. Currently both can be replaced by phpLiteAdmin (with support for SQLite2 and SQLite3) or PhpMinAdmin (now Adminer, which in addition to SQLite supports MySQL, MariaDB and PostgreSQL).
The Spatial Data File (SDF) is a single-user geodatabase file format developed by Autodesk. The file format is the native spatial data storage format for Autodesk GIS programs MapGuide and AutoCAD Map 3D. As of 2014 SDF format version SDF3 (based on SQLite3) uses a single file. Prior versions of the format required a spatial index file (SIF), with an optional key index file (KIF) to speed access to the file. The SDF file format can be created and manipulated using an OSGeo FDO Provider for SDF, which is open-source software. Beyond Autodesk's products, products that can read/write the format include FME from Safe Software, Fdo2Fdo, and the FdoToolbox. The SDF format design uses low-level storage components of SQLite using a flat binary serialization (binary large objects). However, the relational aspects are not present, thus the format cannot be opened with any software designed specifically for SQLite. The format supports multiple feature classes per file and multiple geometry properties per feature class. Each geometry property is indexed using an R-tree. It is optimized for fast spatial reading of large datasets in scenarios involving a single writer and multiple readers.
Mega2 is a data manipulation software for applied statistical genetics. Mega is an acronym for Manipulation Environment for Genetic Analysis. The software allows the applied statistical geneticist to convert one's data from several input formats to a large number output formats suitable for analysis by commonly used software packages. In a typical human genetics study, the analyst often needs to use a variety of different software programs to analyze the data, and these programs usually require that the data be formatted to their precise input specifications. Conversion of one's data into these multiple different formats can be tedious, time-consuming, and error-prone. Mega2, by providing validated conversion pipelines, can accelerate the analyses while reducing errors. Mega2 produces a common intermediate data representation using SQLite3, which enables the data to be accessed by other programs and languages. In particular, the Mega2R R package converts the SQLite3 data into R data frames. Several R functions are provided that illustrate how data can be extracted from the data frames for common R analysis, such as SKAT and pedgene. The key is being able to efficiently extract genotypes corresponding to chosen subsets of markers so as to facilitate gene-based association testing by automating looping over genes in the genome. Another function converts to VCF format and another converts the data to GenABEL format. For more information about the Mega2R package, see here. Mega2 has been used to facilitate genetic analyses of a wide variety of human traits, including hereditary dystonia, Ehlers–Danlos syndrome, multiple sclerosis, and gliomas. A list of PubMed Central articles citing Mega2 can be seen here. Mega2, which focusses on data reformatting, should not be confused with the MEGA, Molecular Evolutionary Genetics Analysis program, which focuses on molecular evolution and phylogenetics.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
