MUMPS to Java - Veterans Health Administration (VHA)
This case study documents technologies, processes, and methods of the timely and 100% automated conversion of a portion of the VHA (Veterans Health Administration) Information Systems and Technology Architecture (VistA) system, written in 2.1 million lines of MUMPS. The modernized module resulted in object-oriented and highly maintainable Java compatible with the J2EE framework. VistA is the core Electronic Healthcare Recordkeeping (EHR) system for the VHA hospital system, which provides EHR record keeping for more than 4.5 million veterans.

TSRI CEO Coauthors OMG Book
"TSRI CEO Coauthors Information Modernization Case Studies Book For The OMG Press" |
Kirkland, WA. (October 10, 2009) – The first major publication from the Object Management Group Architecture Driven Modernization Task Force will be appearing in book stores commencing February, 2010. Published by Morgan Kaufman as part of the OMG Series, the Information System Transformation: Architecture Driven Modernization Case Studies in 400+ pages is already being heralded as the most definitive handbook of best practices for information system modernization published in more than a decade. CTOs, CIOs and System Architects of Organizations seeking guidance in the theory, principles, disciplines, tools, scenarios and management strategies for legacy system modernization will use Information System Transformation: Architecture Driven Modernization Case Studies by Bill Ulrich and Philip Newcomb an irreplaceable handbook for guiding their modernization projects. In contrast to the tangled IT architectures that resulted from decades of manual patches, failed replacements, and outmoded transliteration approaches, ADM is an automated approach for information system modernization that restores the vitality of legacy systems by automatically modeling and transforming them into modern languages, and modern designs and architectures without the need for manual intervention except to adjust the models and rules that carry out the automated modernization process. This new OMG Series publication combines theory and practical guidance from lessons learned during the modernization of major mission critical systems. The European air traffic control system, the Veteran Heath Administration’s electronic health care system, Air Force logistics systems, Navy NMCI systems are just a few of the highly successful modernization projects that are the focus of the many in-depth case studies in this new book. The outcome or a three year collaboration between Philip Newcomb, CEO of the Software Revolution, Inc and principal contributor to the ASTM, SMM and KDM standards and William Ulrich, Co-chair of the Object Management Group (OMG) Architecture-Driven Modernization Task Force (ADM-TF), Information System Transformation: Architecture Driven Modernization Case Studies is the first OMG Series publication to address architecture driven modernization (ADM).

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. 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.
