The concept for creation of service corporate information systems of economic industrial energy clusterThe article discusses the creation of an information system that automates the activities of the
group of coal companies organized in economic production and energy cluster in order to increase
profitability and reduce the cost of the final product. The article considers the metamodel of object
system, the basic elements to represent the classes, associations, attributes. Represented by a class
hierarchy to represent validation rules of object domain. Describes the most popular object-relation
mapping patterns. Presents Single Table Inheritance, Class Table Inheritance and Concrete Table
Inheritance patterns. Metamodel described repeatedly tested on a variety of application domains.
At its base are implemented information systems for agrosystems, fast food restaurants, beauty salons
and in the scientific field. An exemplary organization plan economic cluster coal industry, considered
in detail the need for factories and workshops. Presented a unified methodology for designing
information systems and describes in detail all its main stages. The article describes the range
of products obtained during deep processing of carbonaceous materials and prices on them. The
article shows the basic architecture of a corporate information system developed to ensure effective
functioning of the units in a single cluster. All submitted material is illustrated with class diagrams
unified modeling language UML.

Unified object system metamodel
The article presents a unified object system metamodel, developed by the author and used them
in the development of large software systems over the past few years. This paper is the development
of the material, briefly presented in the article «The Concept Creation Service Corporate Information
Systems of Economic Industrial Energy Cluster», published in the Applied Informatics journal in № 6
from 2014. The urgency of the problem is reasonable overview of existing work presented in this article.
The article presents the latest to date version of the metamodel and describes the main constituent
elements. Attention is paid to the hierarchy of metaclasses used in the simulation application
domain entities. Also considered metaclass hierarchy representing the different types of atomic and
class attributes. Attention is given to the description and dynamic (behavioral) component by implementing
the methods and events classes. Finally, conclusions are made about the future development
work. Behavioral characteristics are implemented through various validation rules. The article
deals with the decisions relating to the management of visibility and accessibility of the individual
elements of graphic controls. All elements of the metamodel was tested under a variety of complex
database applications. Further development of this paper is the development of custom UML-profile
that allows to simplify the process of designing the program and database structure. This profile can
be used in teaching students the design and implementation of software.

Ontological approach in the development of database applicationsThe article deals with analysing of the process of building information system architecture. It was
revealed that the description or the general architecture of the information system is a composition of
descriptions of models built in different notations, using differing semantics. Means and methods for
constructing these models can be separated into independent subsystems in the system providing target
information system design, and the general architecture of the target system depends on the characteristics
of providing the system. Revealed the composition of subsystems forming system provides
design-time Web information system. Ontology developed to formalize the description of information
system architecture that provides the opportunity to determine the configuration of the project development,
system model, and the relationship of ontologies used to represent the sub-systems. We propose
a method of matching the descriptions of models allows you to shape the description of the overall
architecture of the target system and describes the unified metamodel of object system which can
be used for domain-driven design of database system.
