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 />
