DISQLite3 implements a self-contained, embeddable, zero-configuration SQL database engine for Delphi (Embarcadero / CodeGear / Borland).

Overview
ACID transactions, even after system crashes and power failures.
Zero-configuration – no setup or administration needed.
Implements most of SQL-92.
A complete database is stored in a single disk file.
Supports terabyte-sized databases and gigabyte-sized strings and blobs. Self-contained: no external dependencies, no DLLs.
Small footprint and smart linking: Only required code is compiled in, adding as little as 300 KB code space only.
Full Text Search (FTS) with customizable tokenizer, prefix matching, and optional word stemming for 15 languages.
Database AES encryption with SHA256 key generator.
Db.pas is not required, which allows DISQLite3 to compile with all flavours of Delphi, including Delphi Standard and Delphi Personal.
Faster than popular database engines for most common operations.
Simple, easy to use API.
Database files created with DISQLite3 can also be accessed by Linux and MacOS using the SQLite3 libraries.
