Organizations are highly dependent on their software in carrying out their daily activities. Unfortunately, the repeated changes that are applied to these systems make their evolution difficult. This evolution may be necessary to maintain the software, replace or upgrade it. In the case of complex and poorly documented legacy systems, modernization is the only feasible solution to achieving the evolution goals. The OMG (Object Management Group) consortium created the Architecture-Driven Modernization (ADM) initiative to cope with the challenges of modernization. This initiative proposes, among other things, modernization through model-driven engineering (MDE). In this context, the modernization of a legacy system, not developed in an MDE environment, begins with its migration towards this type of environment. This migration raises the problem of finding the models necessary for the use of MDE representing this system.In this paper, we present a new bimodal approach to ADM modernization by enabling automatic and interactive modes to discover a view of the implementation platform of a legacy object-oriented system. Also, we present the key ideas of the algorithms behind this discovery process. Finally, we describe our prototype tool that implements our approach. This tool has been validated on several systems written in C# and Java languages.

Software modernization is a new research area in the software industry that is intended to provide support for transforming an existing software system to a new one that satisfies new demands. Software modernization requires technical frameworks for information integration and tool interoperability that allow managing new platform technologies, design techniques, and processes. To meet these demands, Architecture-Driven Modernization (ADM) has emerged as the new OMG (Object Management Group) initiative for modernization. Reverse engineering techniques play a crucial role in system modernization. This chapter describes the state of the art in the model-driven modernization area, reverse engineering in particular. A framework to reverse engineering models from object-oriented code that distinguishes three different abstraction levels linked to models, metamodels, and formal specification is described. The chapter includes an analysis of technologies that support ADM standards and provides a summary of the principles that can be used to govern current modernization efforts.

Computer Aided Software Engineering (CASE) has been growing faster in software industry. As part of it Model Driven Engineering (MDE) has been around for focusing on models and transforming them from one model to other model. The tool named Extensible Real Time Software Design Inconsistency Checker (XRTSDIC) proposed by us in previous paper supports UML modelling, design inconsistency checking and model transformation from UML to ERD to SQL. In this paper it is extended further to facilitate model transformation from PIM (UML class diagram) to PSM (source code). We proposed an algorithm and defined model transformation and consistency rules. The extended framework has provision for class relationship analysis and support for choosing different object oriented languages like C#, C++ and Java. While transforming the model, we used the concept of dialects. Dialect is the class with transformation functionality which has ability to adapt to syntax and semantics of chosen language. Different dialects are made available for different languages. Thus the proposed system is capable of transforming models and the prototype application we built and extended demonstrates the proof of concept. The empirical results revealed that the model transformation is consistent and accurate.

System Analysis and Design (SAND), is critical for any system development project.  Most new systems are built using Object-Oriented System Analysis and Design (OOSAND).  This paper critically examined and analyzed the OOSAND methodology to discover the underlying principles and rationales based on the inherent processes.  There are a few past studies that had examined the factors influencing the processes but few had examined the processes themselves.  This paper focuses on the SAND processes and examines the pragmatic issues concerning them.  The significance of this research is that the knowledge gained in this exercise will provide systems analyst/programmers a better heuristics to migrate legacy systems to the new object-oriented system and enable higher analyst/programmer efficiency and effectiveness in conducting SAND.
