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.
When that stalwart of facile enterprise development, Visual Basic 6, was retired by Microsoft, it left companies with a variety of problems. While many were able to immediately upgrade to Visual Basic .NET, Java, C++ and other platforms, cases remain in which VB6 was so embedded in the software infrastructure that it could not be easily changed or extricated. TSRI has been working on code transformation of numerous languages for many years, and now includes VB6 transformation.
The Oregon's Public Employees Retirement System (OPERS) serves approximately 300,000 employee members, inactive members and retirees from more than 850 public employers. OPERS required a major maintenance action of the OPERS Benefit Estimation Subsystem (BESS) and Benefit Calculation Subsystem (BCSS) to address changes in Oregon State retirement regulations. TSRI's automated refactoring capability was used to consolidate the applications and remove dead and redundant code.
The Reliability & Maintainability Information System (REMIS) is a key component of the Air Force Depot Maintenance System. REMIS consisted of 3.1 million lines of source code written in COBOL85, TAL and C. The system runs on a Tandem Symmetric Multiprocessor with NonStop SQL/MP DDL and a Tandem database. Northrop Grumman IT (NGIT) maintained REMIS at Wright-Patterson AFB for the Air Force Material System Group (MSG).
TriGeo Network Security, Inc. awarded a sole-source contract to TSRI for documentation and Refactoring of TriGeo’s primary product offering. This "Roundtripping" process involves taking in a client's code, applying pattern based refactorings to change and improve the code without changing the functional equivalency of the application.
