SD, the Multivalue String Database

SD is a multivalue database in the Pr1me Information tradition. It contains open source code from the Open Source databases openQM and ScarletDME and open source code developed by the SD developers after the fork from ScarletDME. While it shares many of the same features, it was forked to explore some new ideas as to what a modern multivalue database should contain.

SD is 64 bit only and runs only on Linux. Releases are tested on the most current release of Debian, Ubuntu, Mint and Fedora. SD should run on any distribution based on Debian 12, Ubuntu 24.04 or Fedora 41. The installer has also installed the database successfully on Ubuntu running under the Windows Subsystem for Linux, and Ubuntu on the Raspberry Pi 5.

SD should cohabit peacefully with existing openQM and ScarletDME installations as it creates and uses a System V shared memory segment that will not conflict with OpenQM or ScarletDME.

The current version of the SD repository contains no binary bits. All features are available for auditing. Binary files are only created during the install.

To install on one of the supported systems, just clone (or download the zip file) of the repository to the target computer and then run the appropriate install script found in the sdb64 directory.

See the sd64/sdsys/changelog file for changes in each version release.
