Architecture Methodology Integration

The objective of this effort is to develop LAMMS (Legacy Architecture Migration & Maintenance Sys-tem) which includes a methodology to convert a structured analysis architecture to an object oriented ar-chitecture and provide an environment that automates that methodology.  Tridents approach is based on its InterchangeSE commercial product, a framework for any enterprise wide systems engineering solution that enables the implementation of processes and the integration of data from various sources into an inte-grated data model for total life-cycle engineering and management of complex systems.  Based on the InterchangeSE approach, Trident will convert the structured analysis architecture into its common data model and then convert from the common data model into an object oriented model.  This is done by de-veloping rules for mapping information from an architecture into the common data model within Inter-changeSE and then developing the automated bidirectional routines that implement those rules.  By main-taining consistency between the tools (i.e. the original structured analysis tool and the resulting UML tool), a program can choose to convert the architecture over time and maintain a hybrid model within In-terchangeSE.  In addition, the LAMMS environment will provide an assessment of how well the integrated model complies with standards like DoDAF and UML. BENEFIT: Most existing Air Force information systems are developed using a structured analysis methodology for systems engineering, software design and development.  The result is that the Air Force spends 70% of its software lifecycle costs on maintenance.  The Air Force anticipates that it can save millions of dollars in maintenance costs each year by converting the structured-analysis code into object-oriented code.  Use of existing code converters to accomplish this task results in programs that do not take full advantage of the modular nature of object oriented code and does not achieve the desired cost reduction.  The methodology and supporting environment that converts the available information at the system engineering level and allows for the traceability within the architecture and down into new object oriented design from which true object oriented code may be developed will realize this cost reduction objective.
