Projects

DSS designed and implemented DACS (the Distributed Access Control System), an open source, light-weight single sign-on system that provides extended authentication and access control capabilities for Apache and web-based services. DACS web services and commands can be used by application software, scripts, server software, and CGI programs for authentication and authorization checking functionality. DACS is a key component of Canada's National Forest Information System (NFIS) and has been deployed by other governmental agencies, businesses, and projects (About DACS).

An updated version of the open source licensed xprompt utility for the X Window System was released on 25-Sep-2019.

For information about tdbm, an embedded high-performance database, please visit its microsite at tdbm.dss.ca.
[I'm not sure at what point tdbm morphed into an acronym for "The DataBase Machine". Officially, it is "Transactional DBM", or "DBM with (Atomic) Transactions".]

DSS was involved in the design and implementation of the NoSQL Dxstore Database System, an open source database for Linux, FreeBSD, and other systems.

Open source software and technical papers

A variety of older open source licensed software is available. Many of these packages still see regular use on a wide variety of platforms. A few packages can be found in commercial products, including millions of Apple Macs, iPhones, iPads, and iPods, as well as being used by other software.

Some older technical papers on distributed databases, directory services, and other topics are also available.

About DSS

Other projects we have recently been working on include:

Incorporated in 1997 and privately-held, DSS can bring an uncommon amount of knowledge and experience to almost any distributed systems project, as is clear from the company's unusually varied list of specialties and exceedingly deep background in many areas.
