Towards a User-Controlled Software Renovation Factory
نویسندگان
چکیده
Part of software maintenance consists in applying program transformations system-wide. In a number of recent papers, a factory approach has been advocated in which one program after another is fed to an assembly line that consists of a sequence of transformation tools. The general feeling seems to be that such factories have to be constructed and operated by specialists (the ‘vendors’). We think this is an undesirable situation. In this paper we present a software renovation factory which is, as much as possible, user controlled. The factory is controlled by means of a graphical user interface. Two modes of control are distinguished: an architectural mode where an operational renovation factory is constructed out of a set of available tools (parsers, unparsers, transformation modules), and an execution mode where the operational factory is applied for renovation purposes. We report about an experiment with a COBOL transformation factory which has been used for the conversion of a real-world business application system. c © 2002 Elsevier Science B.V.

Generation of Software Renovation Factories from Compilers
When a compiler is designed carefully, it is possible to extract its grammar. We reengineer the extracted grammar to one that is geared towards reengineering. From this reengineering grammar we generate an architecture called a software renovation factory. This includes: generic analysis and transformation functionality and a native pattern language using the concrete syntax of the language for...
متن کاملGeneration of Components for Software Renovation Factories from Context-Free Grammars
We present an approach for the generation of components for a software renovation factory. These components are generated from a contex-free grammar de nition that recognizes the code that has to be renovated. We generate analysis and transformation components that can be instantiated with a speci c transformation or analysis task. We apply our approach to COBOL and we discuss the construction ...
متن کاملScaffolding for Software Renovation
We discuss an approach that explores the use of scaaolding of source code to facilitate its renovation. We show that scaaolding is a useful paradigm for software renovation. We designed syntax and semantics for scaaolding, that enables all relevant applications of scaaolding. The automatic generation of extensions to a normal grammar, so that the resulting extension grammar can parse code with ...
متن کاملDesign Patterns for Independent Building Blocks
The pattern language presented in this paper aims at helping designers to develop reusable building blocks that can be plugged together as needed by the application to be built. The patterns try to identify essential properties of reusable software. In particular, we show that extensive standardization is not a necessary prerequisite of reusability as long as interfaces are designed in a way th...
متن کاملIntroduction of supply chain management concepts in e-government research and practice
The paper deals with various aspects of e-government and highlights the importance of the holistic treatment of business process renovation in order to facilitate the transition towards e-government. It analyses both upstream and downstream supply chain renovation and describes a four-step procedure for downstream renovation. A new definition of e-government that includes the whole supply chain...
