(Process Entity Relationships) for semantic data modeling is
presented, based on process and architectural approach. Terms,
symbols and conventions used are explained. The levels of the
model were described, and some example models are given.

Резюме : Все по-бързо развиващата се среда, в която
функционира бизнесът днес, поставя съвременното предприятие пред
предизвикателството да съумява адекватно да реагира на
промените, което от своя страна налага да се използва подходящ
инструментариум за гъвкаво управление[1]. Именно като такъв
инструментариум се разглежда придобиващата все по-голяма
популярност в световен мащаб концепция за архитектура на
предприятието[4]. В доклада се предлага 3D модел на
архитектурата на данните, който е базиран на модела на Gartner
[5].
Ключови думи: архитектурата на предприятието, архитектура
на данните, подход PDCA, SID модел |

Summary: The purpose of this report is to present a
component model corresponding to the modern concepts of
enterprise architecture and to propose some new or modified
components and semantic relationships. From a theoretical point
of view the model is another attempt to define the framework and
components of the enterprise architecture

Резюме: Днес информационните технологии (ИТ) и бизнеса
стават все по взаимосвързани От синхронизацията на степента на
тяхната зрялост в голяма степен зависи успешното развитие на
организациите. В доклада е представен модел на зрялост на
информационните технологии, базиран на модела СММ (Capability
Maturity Model) (5,10).

Summary: The report presented a model
for the description of an enterprise architecture. In this paper
the components of the model are described and appropriate
methodology are presented for its implementation. Methods that
are described in the report optimized the process of Enterprise
architecture. It allows for repeated use of architectural
sollutions tested in practice. Developed Methods enables its
efficient incorporation into the architecture of an enterprise.
Keywords: enterprise architecture, data architecture,
business processes, architecture framework , methodology. |

related to the multiple dimensions of architectural description
and their influence on achieving the current requirements to
develop a dynamic organization-real-time work, adequate response
to the changing external environment and ceaseless improvement.

Summary: Concept of “Building Blocks” has become in recent
years as a leader in developing both the architecture of the
enterprise as a whole and the individual components and −
business applications, data and infrastructure. The report
proposed approach of using “Building Blocks”, in developing the
architecture of data and accurate in their modeling. The
possibilities are described that offered the types of objects
such as “Building Blocks”. Presented taxonomy is used for
modeling the basic types of objects / entities, based on PER
model . Here are concrete examples. We examined the practical
applicability of the developed taxonomy.
Keywords : enterprise architecture, data architecture,
business processes, data modeling, architectural frameworks
models, taxonomy. |

Abstract: The report presents the role, place and objectives
of the data architecture in enterprise architecture. They are
examined in the light of the information architecture and
business process requirements. Тhe roles of data architecture,
basic principles, characteristics and development stages are
described. It can serve as guidance material for IT departments
which begin to implement projects in synchronization of business
and IT [13, 14, 15, 18].

Abstract: The data quality has a very
important role in the business decisions process. For a good
quality, a good models and good procedures are needed. The paper
presents a framework for assessment of the process of data
modelling, based on the maturity model of Harold Kerzner, known
as Project Management Maturity Model (PMMM). Based on this
framework, a concrete indicators/metrics could be described.
They can be used for specifying the maturity level reached by
the organization in the field of data modelling.
Keywords: PMMM, Data Modeling, Maturity Model, Enterprise
Architecture, TQM |

Abstract: The Extended Information Model (EIM), presented in
this paper is intended for data modelling in development of the
Enterprise Architecture. It is the base of data, applications
and infrastructure architectures. In EIM the process oriented
data model PER is used as a main building element. The PER model
appears as a development of principles of semantic data
modelling of E/R model of Chen and ET/P model of Codd. The
proposed model uses the main principles of SID model, further
developed up to using typical data structures in creating
aggregated business entities and their integration with
respective business processes.

Анотация:
Разработката на архитектура на предприятието е процес на
моделиране и документиране на
всички аспекти на организацията. Разработена е таксономия на
данни градивните блокове, която се
базира на три основни класификационни признака: абстракция,
обхват и зрялост. Тя може да
послужи при специфициране и съхранение на информация за
данни градивните блокове.
Разработката може да се прилага като ръководен материал за
ИТ отдели, които започват да
реализират проекти в областта на синхронизацията на бизнеса
и информационните технологии.
Ключови думи: архитектура на предприятия, архитектура
на данните, моделиране на данни,таксономия, EIM, 3D Model,
