(i.e., involvement of more institutions, regional departments of the Ministry of environment;
integration with external data warehouses and Web Services - for reporting the EU, etc.):
institutional setup, manpower; (4) Openness and a proper public participation.
The various types of data providers to the system require that some special software should
be available for them. It can be achieved by implementing a Client/Server system based on
services at the participating data warehouses.
The scheme of relationships between main components of the water resource management
information system prototype, corresponding to the mentioned requirements of technical
interoperability is presented in Fig. 2.
The databases and allocated tools have to be secured by restricted access.
A distributed database system, based on data warehouses (DW) and web services, was
chosen because it improves both the quality of data and the value of the reports. It allows us
to eliminate some of the boring and time consuming work associated with collection of data
from different sources and bringing it on a format so that could be used in the common
context. In addition, it has been decided that the system should be independent of which
type of database provider is selected.
This is the case where the following tools are used: 4 th -generation-language development
environment suitable for a Rapid Application Development; the whole access to the
databases should be performed by use of SQL; XML and its technologies should be used for
data exchange and presentation.
Continually we have had evaluate the situation according to the sustainability in the given
region. For this purposes we deal with the decision support, integrating main components
for evaluation of environment contamination processes (Dzemydiene et al. 2008).
Decision-making aimed to on-line evaluation of the pollution processes of an enterprise
deals with: the complexity of structures of processes; multiple subsystems with complex
mechanism interacting of internal or external parts; time and space/geographical
dependencies; great volume of data acquired from the processes; multi-criteria decision -
making; causal, temporal relationships and interaction of processes.
4.2 Knowledge - based description of processes for contamination evaluation
The main purpose of the advisory system is to assist in environment protection control
processes, creating of suspect profiles by giving computer-aided instructions, planning and
situation recognition techniques. Use of advisory systems may also improve legal training,
for example, providing environment protection agencies with advice on the type of
information required by inspection to reduce the pollution activities. As an example, we
consider the activities of enterprises, firms, and organizations, i.e. the main stationary
objects, to estimate pollution of water bodies. In line with the object functioning nature the
project reflects information on the activities pursued while the license defines the limit in
which environment pollution is allowed, i.e. limits of pollutants cast are drawn. Besides, the
objects must give reports according to their activities pursued and in line with statistical
account ability forms.
The level of representation of dynamical aspects shows the dynamics of observable
processes. The multiple objective decision making deals with the analysis of information
obtained from the static sub-model taking into account all possible measurement points
revealed in dynamic sub-model of such a system. Further actions, operations, etc. are
determined through the mechanism of cooperation of agents that are working by using the
temporal information registration window.
