Transformation of Legacy Software into Client/Server Applications through Pattern-Based Rearchitecturing

Abstract

Evolution styles: Foundations and tool support for software architecture evolution

“…There has been some research into abstracting code to an architectural level, transforming the architecture, and then regenerating code [10], [19]. These approaches focus on methods for retrieving architectures from legacy systems and reflecting (single-step) architectural changes back into the system, and do not deal with how to specify and reason about entire architectural transformations or a sequence of architectural releases.…”

Reducing the Class Coupling of Legacy Code by a Metrics-Based Relocation of Class Members

“…If a strong MemberGroup pattern is found and all previous preconditions are fulfilled, we can relocate the MemberGroup MG strong (m) to the target class T ∈ M tar using the relocation function moveStrongMG: Similar to the relocation algorithm for the common MemberGroup the function moveStrongMG resolves overlapping identifier names and moves the members and dependent constructor statements (lines [3][4][5][6][7][8]. After the relocation of the strong MemberGroup the formerly used variable of type T , passed to the method m as parameter, is unnecessary.…”

“…To support the programmer in different reengineering and restructuring tasks we developed the toolset TransFormr [7]. It extracts the software graph from the source code, based on abstract syntax trees, and offers transformation operations.…”

“…In Section 4 we discuss metrics to support the relocation task in order to reduce class dependencies. We show that the analysis and relocation of MemberGroups can be integrated into reengineering toolsets like TransFormr [7]. We investigate the impact of the relocation of MemberGroups on two open source applications and show the achieved improvements in Section 5.…”
