    MODEL-DRIVEN DEVELOPMENT OF ONLINE SYSTEM FOR E-COMMERCE

    Science. Business. Society., Vol. 1 (2016), Issue 3, pg(s) 58-61

    Nowadays E-commerce is gaining more and more popularity, it contains all possible financial and trade transactions which are made via computer networks. Model-driven software development (MDSD) is the key to create the exact and accurate software application. All the necessary information is taken from a database. The most widely used database management system is MySQL. The latter is an open-source relational database management system, which is written in C programming language. In order to clarify the working process of an organization, a UML class diagram is created. The UML (Unified Modeling Language) is used for making graphical visual models for all the business processes. The paper presents the main stages of e-commerce transaction, using E-shop as an example.

    INFORMATION MODELING OF ONLINE AIR TICKETS RESERVATION SYSTEM

    Science. Business. Society., Vol. 1 (2016), Issue 3, pg(s) 54-57

    Modern society brought high demands on the quality of information systems, which require the use of modern methodologies and software to automate the process and reduce development time of the project and raise its quality. One of the most promising approaches in this direction is the Model Driven Development (MDD), that is an innovative approach for development of different software applications using models at different levels of abstraction and applying model transformation to code generation. The main objective of this paper is to present an approach for model-driven development of online air ticket reservation system based on UML.UML use case diagrams and class diagram are used to model the main requirements and data model of the system respectively in order to achieve reusable and portable models of the system. The developed UML conceptual data model is implemented in a MySQL based database. Finally, some conclusions are made.

  • MODEL DRIVEN DEVELOPMENT OF AGENT BASED AMBIENT INTELLIGENCE PLACES WITH SERVICE ORIENTED ARCHITECTURE

    Machines. Technologies. Materials., Vol. 10 (2016), Issue 2, pg(s) 47-50

    In recent years the use of computer technique and information technology in the domain of Ambient Intelligence (AmI) has been increasing significantly. For successful and efficient development of ambient intelligence systems and their components a new approach is needed. The Model Driven Development (MDD) is an innovative approach for development of different software applications using models at different levels of abstraction and applying model transformation to code generation. In order to satisfy the basic requirements to the developed AmI, in the proposed approach, the MDD, based on Model Driven Architecture (MDA), is directed to combine the use of agents as basic elements of the system and to model the internal and external communications in the system, based on the concept of Service Oriented Architecture (SOA). Such a way, the paper proposes a layered modeling framework for model driven development of agent based AmI systems with service oriented architecture. The deployment of the software on hardware resources is also part of the software process model. Finally some conclusions are made.

    MODELING OF CYBER-PHYSICAL SYSTEMS USING UML PROFILES

    Industry 4.0, Vol. 1 (2016), Issue 1, pg(s) 15-18

    Cyber-Physical Systems integrate computation, networking, and physical dynamics. Systems and computer science has provided a solid foundation for spectacular progress in modeling of engineering software application for real-time and embedded systems. This paper discusses and analyses the possibilities of using UML and its profiles to model cyber-physical systems. Two approaches for modeling of cyber-physical components based on the UML profile for system engineering – SysML and on the MARTE profile for analysis and modeling of real-time systems are respectively described. The presented approaches are illustrated with a simple example for modeling of feedback level control system. Finally some conclusions are made.
