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.

This paper presents the developed domain ontology of the equipment in manufacturing systems in order to be used in the field of reconfigurable manufacturing systems (RMS). The ontology meets the requirements of the meta-class "Equipment", which is part of the developed meta ontology based on the standard for integrated systems for the production and management IEC / ISO 62264. The article explains various properties and class restrictions of the developed ontology. Web Ontology Language (OWL 2) and Protégé 4.3 as an editor and knowledge acquisition tool are used. Special attention is given to the use of ontology reasoning to infer additional information from the facts stated explicitly in ontology – an important feature, used to perform classification, sorting and assembly operations and consistency checking.
