Version 1.0 announcement:

As an end of the year gift to the multivalue community, Don M and Mark B are happy to announce version 1.0 of SD, the open source multivalue string database. This release contains various bug fixes and new features. We have moved the install and delete scripts into their own repository. The install script now handles everything needed to install SD on Fedora and Debian/Ubuntu based distros. In addition, much better error trapping has been added.

Mark has fixed several outstanding bugs in the core SD code base. Included are fixes for the termio.h problem and consistency in OS level file naming . He also has added many new functions for embedded python. PROC is now supported and TAPE and ACCOUNT.RESTORE functionality is available as an optional feature during install. Also, there is better handling of Messages. The repositories are:

Multivalue database solutions are a powerful yet often overlooked type of data management system designed to handle complex, hierarchical, and dynamic data structures with ease. Unlike traditional relational databases, where each field stores only one value, multivalue databases allow fields to contain multiple values — making them highly efficient for applications with variable data formats.

These databases are particularly well-suited for industries like retail, manufacturing, finance, and healthcare, where data is frequently nested, constantly evolving, and performance is critical.

One of the standout benefits of multivalue systems is flexibility. Since fields can store lists, arrays, or dictionaries natively, developers can model real-world data more naturally. This reduces the need for complicated table joins or multiple linked records, simplifying application logic and improving performance.

Popular multivalue database systems include UniData, UniVerse, OpenQM, and Reality, each supporting fast querying, scalability, and integration with modern development tools. Businesses using ERP, CRM, and POS systems…
