Nowadays companies and enterprises collects and stores<br />
huge amounts of data. However according to different evaluations<br />
until recently only not much over 7% of these informations<br />
were using in business strategic decisions making<br />
processes [1,6]. Change of this situation became possible with<br />
popularizing the Business Intelligence (BI) technologies.<br />
Originally the BI applications were understood only as<br />
a specialized systems of the information management. Currently,<br />
BI systems still are being used in their primal role to deliver<br />
information for management support processes but more<br />
often these systems constitutes wide connecting of applications<br />
and technologies used for collecting, aggregation, selection,<br />
analysis and suitable presentation of the business information<br />
derived from different internal and external sources for the purposes<br />
of different business activities of the enterprise [2].<br />
BI systems are the way of the realization of computer/information<br />
integrated systems functioning in the scale of the entire<br />
institution. The reasons are great elasticity and high possibilities<br />
of the company functions optimization of these systems in<br />
many aspects on many organizational levels. BI systems more<br />
and more often make their stores available outside going beyond<br />
organizational structures of companies [8,10].<br />
Characteristic feature of BI systems is using Data Warehouse<br />
technology with advanced mechanisms of automatic<br />
data loading from source databases, data integration and<br />
transfer to central base, On-Line Analytical Processing<br />
(OLAP) multidimensional data analysis tools, and Data Mining<br />
exploration techniques [5].<br />
Objectives<br />
The lack of abilities to obtain practical skills of designing and<br />
using integrated computer information systems in real operating<br />
environment is a stipulation often put forward in relation<br />
to programs of some higher education faculties like a Informatics,<br />
Informatics and Econometrics, Economics, Finances<br />
and Management. The main reason is a lack of appropriate<br />
educational platforms enabling to conduct exercises in form<br />
similar enough to real tasks in job.<br />
The main objective of this paper is a presentation of the<br />
Simulation and Modeling System for Business (SMS-B) conception<br />
as the proposal of the educational platform offering to<br />
the possibilities real integrated information systems. The SMS-<br />
B System is copying architecture and the specificity of the real,<br />
information operating environment of the company/institution<br />
functioning based on generated data simulating real data in the<br />
amount, which is enough to conduct the teaching processes.<br />
In the paper possibilities offered by the SMS-B system are<br />
presented in obtaining of specialized knowledge and professional<br />
skills necessary for different user categories of real computer<br />
information systems: computer team, business users,<br />
business analysts, information consumers. The SMS-B system<br />
can be also successfully used as a computer tool for informatics,<br />
statistics, econometrics and management courses,<br />
especially practical exercises.<br />
In the paper an assessment of courses and teaching hours<br />
number proposed to use of SMS-B in educational platform<br />
character on real faculties in Warsaw University of Life Sciences<br />
in 2008/<strong>2009</strong> academic year is also presented.<br />
System architecture and functionality<br />
The architecture of SMS-B system is characteristic for a structure<br />
of integrated computer information systems functioning<br />
in commercial banks. The final architecture is presented in<br />
Figure. The system was planned to build and introduce in<br />
three main phases. In the first phase a foundation version<br />
signed in Fig. by solid line is building. In the second phase the<br />
