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.

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.

Enterprise interoperability is the ability of disparate and diverse information and control systems to work together efficiently towards mutually beneficial common goals. Some of the main tasks for achieving enterprise interoperability are connected with data and knowledge access and sharing and by use of model transformation. In this paper are presented and discussed several model transformations between different Technological Spaces: RDB, UML and OWL in order to enable ontology-based access to different models of enterprise data. At the core of the approach is the usage of reference models, based on the standard for enterprise integration ISO/IEC 62264.

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.

The present paper illustrates the current state of affairs for most organizations involved in the sphere of Information technologies that run or strive to run projects in accordance with applicable ISO standards and CMMI. This paper presents the target state of affairs and its design with used technologies. Reaching the goal state is summarized by serialization of metamodels in XML, mapping/parsing of metamodels (in XML) to OWL2 DL (RL profile) ontologies (written/exchangeable in RDF/XML), storages of these semantic metamodels and models (ontologies/semantic data) in advanced RDBMSs with support of ontologies, R2RML mapping of existing project-related relational data to semantic data and storage of semantic data in semantic stores hosted in existing RDBMSs or migration to such ones, extraction of non-relational project-related data and mapping of these logical models to a physical (relational) model and integration in RDBMSs to centralize all project-related data all governed by the defined vocabularies (ontologies of CMMI for Development and ISO 15504/ 12207). Achieving the goal state enables stakeholders to query and infer from project-related semantic data to manage, analyze and assess projects against underlaying standards. Through commonly-accepted adapters, semantic data, metamodels and models are exposed to external applications.

For successful and efficient development of unified modeling framework and software process model (SPM) for MES a new approach is needed. In this paper a modeling framework and SPM that integrates UML profile for system engineering SysML, ANSI/ISA-S95 standard and MES-ML modeling language for MES modeling and specification is presented. The proposed approach is illustrated with a real industrial Pick and Place Unit. Finally some conclusions are made.

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.
