چکیده

It can be shown that software process modelling, seen as a general software development control technique, can be applied to more specific components as well. In this paper, we propose a model, a language and a tool dedicated to database engineering. As it is now natural, the model includes the concept of product (schemas and texts) and that of process. A process is intended to solve a class of problem (defined by the target requirements) and describes a class a transformations that apply on products to produce other products. Each process type is defined by its product flows (input/output) and by the strategy through which the enacter (the developper or the tool itself) can solve the problem. The MDL language allows the method engineer to specify the product types and the process types of the method. A MDL text can be compiled and stored in the repository of the DB-MAIN CASE tool in order to customize this tool according to this specific method. Résumé La modélisation des processus d'ingénierie logicielle, vue comme une technique de contrôle de développement de logiciel, peut également être appliquée à des composants plus spécifiques. Dans cet article, nous proposons un modèle, un langage et un outil dédiés à l'ingénierie des bases de données. Le modèle inclut naturellement les concepts de produits (schémas et textes) et de processus. Un processus est destiné à résoudre une classe de problèmes (définie par des besoins) et décrit une classe de transformations appliquées à des produits pour en déduire d'autres. Chaque type de processus est défini par son flux de produits (entrées/sorties) et par la stratégie à suivre par un opérateur (le développeur ou l'outil lui-meme) pour résoudre le problème. Le langage MDL permet à un ingénieur de méthodes de spécifier les types de produits et les types de processus de la méthode. Un texte MDL peut être compilé et enregistré dans le référentiel de l'AGL DB-MAIN afin de personaliser cet outil en concordance avec cette méthode spécifique.

Dynamic modelling of hardness changes of aluminium nanostructure during mechanical ball milling process

In this research, the feasibility of using mathematical modelling in the ball milling process has been evaluated to verify the hardness changes of an aluminium nanostructure. Considering the model of normal force displacement (NFD), the radius of elastic-plastic and normal displacement of two balls were computed by applying analytical modelling and coding in MATLAB. Properties of balls and alum...

The NEO Protocol for Large-Scale Distributed Database Systems: Modelling and Initial Verification

This paper presents the modelling process and first analysis results carried out within the NEOPPOD project. A protocol, NEO, has been designed in order to manage very large distributed databases such as those used for banking and e-government applications, and thus to handle sensitive data. Security of data is therefore a critical issue that must be ensured before the software can be released ...

Physical modelling of caving propagation process and damage profile ahead of the cave-back

The cavability assessment of rock mass cavability and indicating the damage profile ahead of a cave-back is of great importance in the evaluation of a caving mine operation, which can influence all aspects of the mine operation. Due to the lack of access to the caved zones, our current knowledge about the damage profile in caved zones is very limited. Among the different approaches available, p...

Analysis on Geographical Changes and Research on Spatio- Temporal Patterns

As efforts grow to develop spatio-temporal database systems and temporal geographic information systems that are capable of conveying how geographic phenomena change, it is urgent to analyze the impetus and mechanism that the spatio-temporal process happed. The authors proposed a set of universal change patterns for modelling of spatio-temporal processes, which builds a fundamental basis for th...

Investigating Goal-Oriented Requirements Engineering for Business Processes

Business processes are designed to execute strategies that aim at achieving organisational goals. During the last decade, several methods have been proposed that prescribe the use of goal-oriented requirements engineering techniques for supporting different business process management activities, in particular business process modelling. The integration of goal modelling and business process mo...
