Ada to C++ - US Navy - Modem Control Software

TSRI was engaged to modernize US Navy SATCOM Multi-band Terminal (NMT) Modem Control System (MCS) from Ada to C++. To provide SPAWAR with the best modernization approach, Raytheon selected TSRI to transform the existing MCS Ada code into C++ and to re-factor
the C++ toward the desired target architecture. TSRI's fixed-price "integrator ready" deliverable was selected by Raytheon for its low technical risk,
shortened schedule, and low cost.

TSRI Automatically Modernizes OpenVistA

 

Kirkland, WA. (March 12, 2010) – One of the best kept secrets in Washington DC is that our nation’s veterans already have a comprehensive electronic health care record (EHR) that for decades has supported delivery of quality health care at more than a 160 VHA hospitals around the world.  That extraordinary system is VistA, the Veteran Information System Technical Architecture.  Written in MUMPS, VistA serves as the vital backbone of the Veterans Health Administration (VHA) Electronic Health Care Record System (EHRS) that manages medical record data and delivers medical informatics to the veteran’s bedside while tracking and managing 100% of veteran’s health care electronically throughout his journey through the VHA medical care system.

Visit the VHA’s OpenVistA® Transformation Blueprint at
http://www.tsri.com/open-vista

Ironically, VistA like many systems that are highly successful, is now threatened with self-extinction due to its need for continuous growth and the inability of MUMPS, the language it is written in, to sustain its continued evolution.  VistA suffers from a form of software arthritis common among many legacy systems. Due to its age, size and complexity VistA is brittle, inflexible and resistant to change, and its maintenance costs have gone through the roof, compromising the VHA’s ability to grow and evolve Vista as the foundation for a 21st century medical delivery system for its veterans.

In 2005 the VHA estimated automated modernization of VistA could save the VHA upwards of $3 Billion compared to redevelopment, or manual replacement.  With the announcement today by The Software Revolution, Inc (TSRI), (the world-leading supplier of architecture driven modernization (ADM-based) solutions), of its open-source Transformation Blueprint ® for OpenVistA, TSRI has made a huge start on this daunting challenge.  For those who might care to understand, the OpenVistA Transformation Blueprint ® is a major step towards achievement of the VHA's goal of modernizing its Electronic Healthcare Record  system for its veterans. 

OpenVistA Casestudy

TSRI’s OpenVistA® Transformation Blueprint ® provides the complete target Java code and UML design for the transformation of all 2.1 Million lines of OpenVistA® and 120,000+ lines of Fileman MUMPS code.  The OpenVistA® Transformation Blueprint ® is far more than a mere language translation.  It is a massive multi-million page (300GB) web-based software design and architecture document consisting of navigable hypertext of the 'As-Is' MUMPS and 'To-Be Java' hyperlinked to hundreds of thousands of State Machine Graphs, Cause-Effect Graphs, State-Transition Tables, Control Flow Graphs, Data-Flow Graphs, Structure Charts, Data Element Tables, Class Diagrams expressed as scalable graphical diagrams that richly document all of the MUMPS and target Java/J2EE code. The Transformation Blueprint ® is both an application portfolio as well as a complete architectural roadmap towards a modernized OpenVistA® and Fileman. Every statement of MUMPS in OpenVistA® is shown side-by-side with its transformation into Java/ J2EE along with an extensive array of software property-oriented metric indices (e.g. fan-in, fan-out, complexity, redundancy, dead code, etc) for navigation to the code measured by the property. 

To learn more about TSRI’s transformation of OpenVistA® and the company’s plans for evolving OpenVistA® towards a modernized universal EHR system of the future, read the Chapter 12 casestudy: Veterans Health Administration’s VistA MUMPS Modernization Pilot in William Ulrich and Philip Newcomb’s new book Information Systems Transformation: Architecture-Driven Modernization CaseStudies, just published by Morgan Kaufmann, February 2010 as part of the Object Management Group (OMG) OMG Series.

Code Modernization: Focus on ADA

Ada was designed and released from 1977 to 1983 as a high-level object-oriented language for use in real time and embedded systems. It is used extensively in systems such as air traffic management systems, banking and financial systems, communication and navigational satellites, medical equipment, and in military applications. Currently, although the Ada language has been updated, it is not as common as it once was. The ratio of Java programmers to Ada programmers is now about 20 to 1.

Code modernization can create some interesting problems these days as business and government attempt to upgrade legacy systems. The route ahead is not always clear. Legacy systems may be in a variety of different languages installed for different purposes to meet the needs of the time. Even the transformation target itself can be problematic. Whether code is better translated into Java, a C variant, Python or something else demands consideration of the environment in which the code will reside, its interconnections, as well as the characteristics of the output language and its suitability. Economics rises as an important issue with older or obscure languages that do not have a breadth of available talent.
