The Sombers Group, a custom software house, has been building large real-time systems for its customers for over thirty years. Our multi-platform expertise includes HP NonStop, HP OpenVMS, IBM, Unisys, Stratus, Sun, UNIX, and PC systems.
Most of Sombers’ development today deals with complex, real-time distributed applications over a wide range of disparate platforms. In addition to full turnkey systems development, Sombers provides architectural designs, performance analysis, reliability analysis, test specifications, and regression test environments.
its more than three decades in business, The Sombers Group has actively
provided presentations, training seminars, and interviews on a variety of
subjects. We also have
produced an extensive library of white papers and articles.
Two members of our staff are book authors as well.
Below you will find a list of some of
our most current white papers and documentation.

…a tongue-in-cheek explanation of the simple accounting terms that give rise to a great deal of confusion for programmers who have never been exposed to formal accounting principles. It derives the basic accounting equation relating assets, liabilities, and net worth.
…because of the many turnkey systems we have built, The Sombers Group has become adept at system testing. We have written volumes of test specifications and have created extensive regression test systems for our customers. This white paper describes the various options that an organization can consider in evaluating the application of regression testing to their systems.
of Sombers’ work, especially with respect to its middleware product
NetWeave, has been done in Europe. Many of the European countries are
going through a major rework of their computer systems to accommodate
their new currency, the euro. And this is just after they finished their
Y2K work. This paper, published in the November/December, 1998, issue of
the Tandem Connection, discusses the data
processing impact of the euro conversion.
…most of the systems built by The Sombers Group have carried stringent performance requirements. “Performance Analysis” describes our approach to the performance modeling, measurement, and enhancement of customer applications.
…The Sombers Group’s focus on mission-critical systems means that we have had to become experts in building reliability into our systems. Reliability implies high availability (5 9s), fast recovery, transaction integrity, and database integrity. Our white paper explores the calculation of availability and the study of transaction integrity.
…Nassi-Schneiderman (NS) charts are an alternative to the overly flexible flow chart. They successfully enforce structure and modularity in the programming process. An excellent NS charting tool is available, and it makes the use of Nassi-Schneiderman charts quite painless. This white paper describes NS charts and illustrates their advantage in the modern world of structured programming.
…The Sombers’ Group’s strong
multi-platform background and Web expertise enables us to provide your Web
applications with real-time access to your enterprise data and
applications. We take
advantage of the new XML standards now supported by most Web tools and by
today’s powerful and flexible messaging middleware.
Our white paper describes our methodology for integrating your B2B
and B2C web sites with the legacy systems that support your enterprise.
