The classical software configuration management, which deals with source code versioning, becomes insufficient in the world where most components are distributed in a binary form. This paper focuses on solving versioning issues in the SOFA/DCUP (software appliances/dynamic component updating) component environment. However, many ideas introduced in this paper are applicable in other component-based environments. The paper incorporates the following versioning issues: component and type identification, component and type evolution, component version description model and component retrieving based on the version description model. It also outlines a prototype repository designed as a proof of concept.","PeriodicalId":141256,"journal":{"name":"International Conference on Software Maintenance, 2003. ICSM 2003.

This is true especially in the case of renewal of legacy systems, where the current and well established approaches also fail. This paper presents an application of the method named dynamic calibration for effort estimation of renewal projects together with its experimental validation. The approach satisfies all the requirements of the estimation models. The results obtained by applying dynamic calibration are compared with those obtained with a competitor method: estimation by analogy. The results are shown to be promising although further experimentation on field is needed.","PeriodicalId":141256,"journal":{"name":"International Conference on Software Maintenance, 2003. ICSM 2003.

It is therefore required that the software architecture is also maintained, i.e. sufficiently documented, clearly communicated, and explicitly controlled. In our experience, these requirements cannot be met without appropriate support. Commercial-off-the-shelf support for architectural maintenance is still scarcely available, if at all, implying the need to develop appropriate proprietary means. In this paper, we briefly report upon an overall approach taken within three organizations within Philips that develop professional systems. We extensively describe the experience gained with the embedding of architectural support in these three organizations. We focus on architectural support in the area of software architecture recovery, visualization, analysis, and verification. In our experience, the support must be carried by a number of elements of software development, and all of these elements have to go through a change process to ensure sustainable embedding. We distinguish four of these elements, i.e. process, organization, software development environment, and humans, and present our experience in terms of those elements.","PeriodicalId":141256,"journal":{"name":"International Conference on Software Maintenance, 2003.

The value of IT-business does not only lie in the products but also in the needs it serves. More and more customers require the IT companies with which they do business to continuously improve the speed and quality of their service. To provide seamless high quality service, the collaborating IT-companies/departments must organize themselves in a way so that they can act as one virtual enterprise providing a single point of contact. In this paper, we study how thirty eight companies belonging to thirty seven independent virtual enterprises have organized themselves in order to provide optimal maintenance service to their customers. Our goal is to provide a basis for future support process models and for future business models. Our results show strongly diversified infrastructures of confluent service organizations.

It basically entails re-testing the software with previous test cases to confirm that the modifications made to the software do not have an adverse effect. But re-executing all test cases is normally cost prohibitive, and thus much research has been done on selecting test cases from a test suite without compromising the reliability of the software. These regression test selection techniques find test cases that will not detect any bugs in the modified software, and delete those from the next regression test suite. However, these techniques are based on analysis of source code. Recent programming environments have seen a proliferation of virtual machines. For example, programs written in Java and with the Microsoft .Net Framework are compiled into a platform-independent intermediate code which is executed. Such code could also be used for regression test selection. This especially holds for the Microsoft .Net Framework which handles various programming languages, such as Visual Basic and C++. Thus, this paper presents a safe regression test selection technique for virtual machine based programs. We especially target the Microsoft .Net Framework. Evaluation on 10 different examples resulted in an average of a 40.4% decrease in the cost of regression testing.","PeriodicalId":141256,"journal":{"name":"International Conference on Software Maintenance, 2003.

The project in question is the maintenance and evolution of a very large and complex banking application system for securities processing which has been in progress since several years. Eight factors are defined and evaluated in accordance with the existing literature on software maintenance and with the experience gained on several such maintenance projects. Each of the eight factors is scored according to a given metric scale. It is left to the evaluator to weigh and evaluate the significance of the individual factors. The study is based on empirical data collected over the duration of the project and is intended to contribute to the overall knowledge of software maintenance management.","PeriodicalId":141256,"journal":{"name":"International Conference on Software Maintenance, 2003.

To preserve source code comprehensibility, we need to be able to predict how this property will change. This would allow the construction of a tool to suggest what information should be added or clarified (e.g. in comments) to maintain the code's comprehensibility. We propose a framework to characterize types of concept change during evolution. It is derived from an empirical investigation of concept changes in evolving commercial COBOL II files. The framework describes transformations in the geometry and interpretation of regions of source code. We conclude by relating our observations to the types of maintenance performed and suggest how this work could be developed to provide methods for preserving code quality based on comprehensibility.","PeriodicalId":141256,"journal":{"name":"International Conference on Software Maintenance, 2003.

Munson","doi":"10.1109/ICSM.2003.1235409","DOIUrl":"https://doi.org/10.1109/ICSM.2003.1235409","url":null,"abstract":"Over the past several years, we have been developing methods of measuring the change characteristics of evolving software systems. Not all changes to software systems are equal. Some changes to these systems are very small and have low impact on the system as a whole. Other changes are substantial and have a very large impact of the fault proneness of the complete system. In this study we will identify the sources of variation in the set of software metrics used to measure the system. We will then study the change characteristics to the system over a large number of builds. We have begun a new investigation in these areas in collaboration with a flight software technology development effort at the Jet Propulsion Laboratory (JPL) and have progressed in resolving the limitations of the earlier work in two distinct steps. First, we have developed a standard for the enumeration of faults. This new standard permits software faults to be measured precisely and accurately. Second, we have developed a practical framework for automating the measurement of these faults. This new standard and fault measurement process was then applied to a software system's structural evolution during its development. Every change to the software system was measured and every fault was identified and tracked to a specific code module. The measurement process was implemented in a network appliance, minimizing the impact of measurement activities on development efforts and enabling the comparison of measurements across multiple development efforts. In this paper, we analyze the measurements of structural evolution and fault counts obtained from the JPL flight software technology development effort. Our results indicate that the measures of structural attributes of the evolving software system are suitable for forming predictors of the number of faults inserted into software modules during their development, and that some types of change are more likely to result in the insertion of faults than others. The new fault standard also insures that the model so developed has greater predictive validity.","PeriodicalId":141256,"journal":{"name":"International Conference on Software Maintenance, 2003.

During these builds, software is compiled, linked, and (re)tested with the goal of validating its basic functionality. Although successful for conventional software, smoke tests are difficult to develop and automatically rerun for software that has a graphical user interface (GUI). In this paper, we describe a framework called DART (daily automated regression tester) that addresses the needs of frequent and automated re-testing of GUI software. The key to our success is automation: DART automates everything from structural GUI analysis; test case generation; test oracle creation; to code instrumentation; test execution; coverage evaluation; regeneration of test cases; and their re-execution. Together with the operating system's task scheduler, DART can execute frequently with little input from the developer/tester to retest the GUI software. We provide results of experiments showing the time taken and memory required for GUI analysis, test case and test oracle generation, and test execution. We also empirically compare the relative costs of employing different levels of detail in the GUI test cases.","PeriodicalId":141256,"journal":{"name":"International Conference on Software Maintenance, 2003.

While designing object interactions is far more complex than designing the object structure in forward engineering, the problem of understanding object interactions during code evolution is even harder, because the related information is spread across the code. In this paper, a technique for the automatic extraction of UML interaction diagrams from C++ code is proposed. The algorithm is based on a static, conservative flow analysis that approximates the behavior of the system in any execution and for any possible input. Applicability of the approach to large software is achieved by means of two mechanisms: partial analysis and focusing. Usage of our method on a real world, large C++ system confirmed its viability.","PeriodicalId":141256,"journal":{"name":"International Conference on Software Maintenance, 2003. ICSM 2003.
