A Repository based approach to Data Reverse Engineering
نویسندگان
چکیده
In this paper we describe an experience of Data Reverse Engineering supported by a repository of conceptual schemas.We first introduce a set of integration/abstraction primitives that are used in order to organize a large set of conceptual schemas in a repository. We describe the methodology conceived to produce the repository of schemas of central public administrations in Italy. Then we describe an heuristic methodology, applied in the production of the set of schemas of the public administrations of an italian region. We also compare the former exact methodology and the heuristic one according to their correctness, completeness, and efficiency.

متن کاملCreating and Analyzing Source Code Repository Models - A Model-based Approach to Mining Software Repositories
With mining software repositories (MSR), we analyze the rich data created during the whole evolution of one or more software projects. One major obstacle in MSR is the heterogeneity and complexity of source code as a data source. With model-based technology in general and reverse engineering in particular, we can use abstraction to overcome this obstacle. But, this raises a new question: can we...

متن کامل21 Supporting Reverse Engineering Tasks with a Fuzzy Repository Framework
Software reverse engineering (RE) is often hindered not by the lack of available data, but by an overabundance of it: the (semi-)automatic analysis of static and dynamic code information, data, and documentation results in a huge heap of often incomparable data. Additionally, the gathered information is typically fraught with various kinds of imperfections, for example conflicting information f...
متن کاملConsidering chain to chain competition in forward and reverse logistics of a dynamic and integrated supply chain network design problem
In this paper, a bi-objective model is presented for dynamic and integrated network design of a new entrant competitive closed-loop supply chain. To consider dynamism and integration in the network design problem, multiple long-term periods are regarded during planning horizon, so that each long-term period includes several short-term periods. Furthermore, a chain to chain competition between t...
