An Approach for Transforming CIM to PIM up To PSM in MDA

Ethereum’s Smart Contracts Construction and Development using Model Driven Engineering Technologies: a Review

Currently, in the field of the software engineering industry, end-users have become extremely requiring; consequently, this industry knew a critical evolution. In this vein, the model generation becomes an awakening and an essential step for many approaches among them we cite the Model Driven Architecture (MDA) approach. The Object Management Group (OMG), the founder of the MDA approach, proposes three different abstraction levels; which are the higher level, average level, and lower level. Until now, most research deal with the transformation at the average and the lowest MDA levels, while ignoring the higher level, which precisely contains the requirements’ models. Therefore, our aim in this paper is to construct a sound and more consistent higher MDA level for e-business information systems by automatically generating a higher level of functional requirements model from the Business Value model. Our source Business Value model is represented by the E3value model, whereas the UML Use Case diagram expresses the generated model. The transformation is performed automatically using ATLAS Transformation Language (ATL).

A Novel Automatic Transformation Method from the Business Value Model to the UML Use Case Diagram

The way a database schema is designed has a high impact on its performance in relational databases, which are symmetric in nature. While the problem of schema optimization is even more significant for NoSQL (“Not only SQL”) databases, existing modeling tools for relational databases are inadequate for this asymmetric setting. As a result, NoSQL modelers rely on rules of thumb to model schemas that require a high level of competence. Several studies have been conducted to address this problem; however, they are either proprietary, symmetrical, relationally dependent or post-design assessment tools. In this study, a Dynamic Schema Proposition (DSP) model for NoSQL databases is proposed to handle the asymmetric nature of today’s data. This model aims to facilitate database design and improve its performance in relation to data availability. To achieve this, data modeling styles were aggregated and classified. Existing cardinality notations were empirically extended using synthetically generated queries. A binary integer formulation was used to guide the mapping of asymmetric entities from the application’s conceptual data model to a database schema. An experiment was conducted to evaluate the impact of the DSP model on NoSQL schema production and its performance. A profound improvement was observed in read/write query performance and schema production complexities. In this regard, DSP has significant potential to produce schemas that are capable of handling big data efficiently.

Transformations’ Study Between Requirements Models and Business Process Models in MDA Approach

Nowadays the software industry has known a significant growth, while the end-users have become very demanding. In this sense, the model transformation has become one of the essential solutions to ensure competitiveness in the field of the software industry domain. For that, the Object Management Group (OMG) proposes for the Model-Driven Architecture (MDA) approach three abstraction levels, namely Computation Independent Model (CIM), Platform Independent Model (PIM) and Platform Specific Model (PSM). Therefore, our contribution in this paper is to shed more light on the first MDA transformation, which is the transformation from CIM to PIM levels. We propose a disciplined Model-Driven approach for the e-business information system, which generates the IFML (Interaction Flow Modeling Language) model automatically in the PIM level from business value model in the CIM level, using the ATL transformation language. For this purpose, the business value model is illustrated by the E3value model, whereas, the IFML model exhibits the front-end applications content, interface composition, user interaction and control behavior for several kinds of applications, such as web applications, mobile applications and desktop applications.

An Automatic Transformation Method from the E3value Model to IFML Model: An MDA Approach

Since the Model Driven Architecture (MDA) approach appearance, model’s transformation has been considered as one of the main computing keys in the software industry, which grows exponentially to ensure competitiveness. For that, the Object Management Group (OMG) offers for the MDA approach three abstraction levels, which are Computation Independent Model (CIM), Platform Independent Model (PIM) and Platform Specific Model (PSM). Most researchers put much focus on the PIM to PSM transformation because these levels have multiple common points, but they disregard the CIM to PIM transformation. So, our defiance in this paper is to propose a disciplined method that generates the UML2 Sequence diagrams automatically from the E3value model. Therefore, we produce the UML’s behavior and interaction model in the PIM level, from the value-based requirements model in the CIM level. The transformations are done automatically using the Atlas transformation language (ATL). The purpose is to reduce the effort, time, and the development cost of projects as all transformations is automated, increasing the chance of being more competitive in the software industry.
