Privacy-Preserving Reengineering of Model-View-Controller Application Architectures Using Linked Data

When a legacy system’s software architecture cannot be redesigned, implementing additional privacy requirements is often complex, unreliable and costly to maintain. This paper presents a privacy-by-design approach to reengineer web applications as linked data-enabled and implement access control and privacy preservation properties. The method is based on the knowledge of the application architecture, which for the Web of data is commonly designed on the basis of a model-view-controller pattern. Whereas wrapping techniques commonly used to link data of web applications duplicate the security source code, the new approach allows for the controlled disclosure of an application’s data, while preserving non-functional properties such as privacy preservation. The solution has been implemented and compared with existing linked data frameworks in terms of reliability, maintainability and complexity

An Empirical Study of a Repeatable Method for Reengineering Procedural Software Systems to Object- Oriented Systems

This paper describes a repeatable method for reengineering a procedural system to an object-oriented system. The method uses coupling metrics to assist a domain expert in identifying candidate objects. An application of the method to a simple program is given, and the effectiveness of the various coupling metrics are discussed. We perform a detailed comparison of our repeatable method with an ad hoc, manual reengineering effort based on the same procedural program. The repeatable method was found to be effective for identifying objects. It produced code that was much smaller, more efficient, and passed more regression tests than the ad hoc method. Analysis of object-oriented metrics indicated both simpler code and less variability among classes for the repeatable method

SMEs COMPETITIVE ADVANTAGE AND ENTERPRISE RESOURCE PLANNING IMPLEMENTATION: FINDING FROM CENTRAL JAVA

Enterprise Resource Planning (ERP) is an integrated application software for widespread use in the organization. The aim of this study is to determine factors that affect the successful implementation of ERP in Small and Medium Enterprises (SMEs) in Central Java in order to build competitive advantage. To test the hypothesis, this study utilized data from 107 SMEs in Central Java. The results revealed that variable Business Process Reengineering have the greatest influence toward the successful implementation in Small and Medium Enterprises. It is suggested that SMEs should gain knowledge and solidify its business process reengineering before implementing ERP

ISICSoo: a class for the calculation of ionization cross sections from ECPSSR and PWBA theory

ISICS, originally a C language program for calculating K-, L- and M-shell ionization and X-ray production cross sections from ECPSSR and PWBA theory, has been reengineered into a C++ language class, named ISICSoo. The new software design enables the use of ISICS functionality in other software systems. The code, originally developed for Microsoft Windows operating systems, has been ported to Linux and Mac OS platforms to facilitate its use in a wider scientific environment. The reengineered software also includes some fixes to the original implementation, which ensure more robust computational results and a review of some physics parameters used in the computation. The paper describes the software design and the modifications to the implementation with respect to the previous version; it also documents the test process and provides some indications about the software performance.Comment: Preprint submitted to Computer Physics Communication

Towards a methodology for the development of integrated IT infrastructures

In this paper, the authors propose and validate a methodology for the development of integrated Information Technology (IT) infrastructures. The motivation for putting forward a new methodology is grounded on the limitations of the various software engineering methodologies (traditional) that exist today. Despite that the traditional methodologies result in the development of Information Systems (IS) from scratch, Enterprise Application Integration (EAI) builds integrated IT infrastructures using existing applications. This significant difference is associated with many issues needed to be realised and addressed like: (a) the changes that such an infrastructure brings to organisations, (b) the resistance to change and (c) the extension of IS lifecycle’s. The proposed methodology consist of eight stages and aims at supporting software engineers, organisations and researchers to build integrated IT infrastructures. As a result the methodology seeks to contribute to the body of knowledge

System implementation: managing project and post project stage - case study in an Indonesian company

The research reported in this paper aims to get a better\ud understanding of how the implementation process of\ud enterprise systems (ES) can be managed, by studying the\ud process from an organisational perspective. A review of\ud the literature on previous research in ES implementation\ud has been carried out and the state of the art of ES\ud implementation research is defined. Using several body of\ud literature, an organisational view on ES implementation is\ud described, explaining that ES implementation involves\ud challenges from triple domain, namely technological\ud challenge, business process related challenge, and\ud organisational challenge. Based on the defined state of the\ud art and the organisational view on ES implementation\ud developed in this research, a research framework is\ud presented, addressing the project as well as the postproject\ud stage, and a number of essential issues within the\ud stages. System alignment, knowledge acquisition, change\ud mobilisation are the essntial issues to be studied in the\ud project stage while institutionalisation effort and\ud continuous improvement facilitation are to be studied in\ud the post-project stage. Case studies in Indonesian\ud companies are used to explain the framework
