SQLite Data Access Components (LiteDAC) is a library of components that provides native connectivity to SQLite from Delphi and C++Builder including Community Edition, as well as Lazarus (and Free Pascal) on Windows, Linux, macOS, iOS, and Android. LiteDAC is designed for programmers to develop truly cross-platform desktop and mobile SQLite database applications with no need to deploy any additional libraries.

SQLite Data Access Components (LiteDAC) Features

  • Native Connectivity to SQLite - LiteDAC-based DB applications are easy to deploy, do not require installation of other data provider layers (such as BDE or ODBC), and that's why they can work faster than the ones based on standard Delphi data connectivity solutions. Moreover, LiteDAC provides an additional opportunity to work with SQLite in Delphi and C++Builder directly by linking of the client library statically in your application.
  • SQLite Encryption - To protect your data from unauthorized access, LiteDAC provides a powerful and customizable SQLite Database Encryption engine. You no longer have to spend money to buy expensive SQLite client libraries with support for encryption - with Static Linking, encryption support will be automatically added to your application and the following algorithms will be able to protect your data: AES, Blowfish, TripleDES, Cast128, RC4. LiteDAC allows to use any third-party SQLite library with SQLite Encryption support as well.
  • Cross-Platform Development in Delphi, C++Builder, and Lazarus - LiteDAC provides possibility of cross-platform development using various IDEs: RAD Studio, Delphi, C++Builder, Lazarus (and FPC) on Windows, Mac OS X, iOS, Android, Linux, and FreeBSD for both x86 and x64 platforms. LiteDAC also provides support for the FireMonkey platform, which allows you to develop visually spectacular high-performance desktop and mobile native applications.
  • Wide Coverage of SQLite Features - By providing access to the most advanced database functionality, LiteDAC allows developers to harness the full capabilities of the SQLite and optimize their database applications. LiteDAC supports such SQLite features as working with user-defined functions, database encryption, and more.
  • Static Linking - Linking the SQLite library statically in your application ensure, that your application uses exactly the same version of SQLite, with which it was developed and tested. Also it makes deployment easier.
  • Mobile Development - Develompent for iOS and Android mobile devices using LiteDAC becomes easier, as LiteDAC allows your mobile applications to work with SQLite database as simply as desktop applications do.
  • 64-bit Development - LiteDAC doesn't limit your choice of the development platform. Now you can develop for 32-bit and 64-bit platforms with Delphi and Lazarus (and FPC).
  • Data Type Mapping - If you want to make custom correspondence between SQLite and Delphi data types, you can use a simple and flexible Data Type Mapping engine provided by LiteDAC.
  • Development Platforms - Now you can develop not only VCL-based applications in Delphi and LCL-based ones in Lazarus, but also use the newest FireMonkey application development platform.
  • Performance - All the components and libraries are designed to help you write high-performance, lightweight data access layers, therefore they use advanced data access algorithms and techniques of optimization.
  • Monitoring - Use the dbMonitor tool to monitor and analyze all the DB calls made by your application using SQLite data access components. dbMonitor performs per-component tracing of SQL statement execution, commits, rollbacks, etc.

The Standard edition includes the LiteDAC basic connectivity components. LiteDAC Standard Edition is a cost-effective solution for database application developers who are looking for overall high performance connectivity to SQLite.

The Professional edition shows off the full power of LiteDAC, enhancing LiteDAC Standard Edition with support for SQLite-specific functionality, such as access to SQLite in Direct Mode using Static Linking of SQLite library in an application, Database Encryption, and advanced dataset management features.

You can get Source Access to the LiteDAC Professional Editions by purchasing special LiteDAC Professional Edition with Source Code. The Professional edition includes the source code for all component classes. The source codes of DataSet Manager are not distributed. The source code of SQLite Direct mode is supplied as precompiled packages.
