A Model Driven Reverse Engineering Framework for Extracting Business Rules out of a Java Application

International audienceIn order to react to the ever-changing market, every organization needs to periodically reevaluate and evolve its company policies. These policies must be enforced by its Information System (IS) by means of a set of business rules that drive the system behavior and data. Clearly, policies and rules must be aligned at all times but unfortunately this is a challenging task. In most ISs implementation of business rules is scattered among the code so appropriate techniques must be provided for the discovery and evolution of evolving business rules. In this paper we describe a model driven reverse engineering framework aiming at extracting business rules out of Java source code. The use of modeling techniques facilitate the representation of the rules at a higher-abstraction level which enables stakeholders to understand and manipulate them

Un Framework dirigé par les modèles pour l'extraction de règles métier à partir d'applications COBOL

National audienceCompanies rely on the logic embedded in their Information Systems; that are often legacy applications not designed to represent and operationalize business logic independently from the technical aspects of the applications. Consequently, legacy systems are not able to respond quickly to the new requirements constantly demanded by the market. Discovering and tuning business logic in a legacy system, are time-consuming and error-prone activities, since each time the source code must be analysed, modi fied and tested. In order to simplify these activities, this paper proposes a model driven engineering framework for extracting business logic. Model Driven Engineering is used to ease the discovery and representation of the extracted logic providing understandable output artifacts.Les entreprises s'appuient sur la logique métier encodée dans leurs systèmes d'information. Ce sont souvent des applications existantes qui ne sont pas conçues pour représenter et operationnaliser cette logique independamment des aspects techniques. Par consequent, ces systèmes ne sont pas capables de répondre rapidement aux nouvelles exigences requises par le marche. La découverte et la gestion de la logique métier dans les applications sont des activités qui consomment beaucoup de temps et qui sont sources d'erreurs, car à chaque fois le code doit être analyse, modifié et testé. Afin de simplifier ces activites, ce papier propose un framework dirigé par les modèles pour l'extraction de la logique m étier. L'Ingénierie Dirigée par les Modèles est utilisée pour découvrir et répresenter la logique extraite en fournissant des artefacts en sortie qui aident à sa comprehension

Extracting Business Rules from COBOL: A Model-Based Framework

International audienceOrganizations rely on the logic embedded in their Information Systems for their daily operations. This logic implements the business rules in place in the organization, which must be continuously adapted in response to market changes. Unfortunately, this evolution implies understanding and evolving also the underlying software components enforcing those rules. This is challenging because, first, the code implementing the rules is scattered throughout the whole system and, second, most of the time documentation is poor and out-of-date. This is specially true for older systems that have been maintained and evolved for several years (even decades). In those systems, it is not even clear which business rules are enforced nor whether rules are still consistent with the current organizational policies. In this sense, the goal of this paper is to facilitate the comprehension of legacy systems (in particular COBOL-based ones) by providing a model driven reverse engineering framework able to extract and visualize the business logic embedded in them

Extracting Business Rules from COBOL: A Model-Based Tool

International audienceThis paper presents a Business Rule Extraction tool for COBOL systems. Starting from a COBOL program, we derive a model-based representation of the source code and we provide a set of model transformations to identify and visualize the embedded business rules. In particular, the tool facilitates the definition of an application vocabulary and the identification of relevant business variables. In addition, such variables are used as starting point to slice the code in order to identify business rules, that are finally represented by means of textual and graphical artifacts. The tool has been developed as an Eclipse plug-in in collaboration with IBM France

Properties and Microstructure of Thermo-Pressed Wheat Gluten Films: a comparison with Cast Films

International audienceWheat gluten films were prepared by thermo-pressing, and their mechanical properties were compared to those of cast films. The stress−strain relationship was established for films with various amounts of glycerol. Both relationships were quite different, revealing a different network organization. Thermo-pressed films presented higher stress values than cast films, but the effect of the glycerol amount was similar in both cases, an increase of the glycerol amount leading to a decrease of both films stress. The glycerol influence on the strain at break of thermo-pressed films was very limited, with strain values reaching a maximum around 200%. The role of disulfide bridges on themomoulded films mechanical properties was investigated, and it was shown that some rearrangements and a significative protein insolubilization occurred during the process. The effective flow porosity of the protein network for thermo-pressed films was estimated by water capillary rise measurements to about 7%. Scanning electron microscopy was used to obtain some information about the microstructure of both cast and thermo-pressed films
