Today the GRID related researches and developments are far beyond the closed walls of scientific workshops. The development of a usable business model is being urged by the size and variegation of never-before-presumed application potentials. The GRID –thanks to the creation of available computing capacity and broadband data transfer- is able to form and operate such virtual organizations, that can integrate collaborative communities, geographically scattered resources into a virtual whole. As a result, a heavy-duty supercomputer storage capacity and computing efficiency comes off, even in a desktop computer environment. EGEE (Enabling Grid for E-SciencE) –established in the EU’s 6.Framework Programme- is the biggest supported GRID project in the European Union. EGEE’s main goal is to let scientists from different fields be able to make virtual organizations to expand the research capacity, to enhance the efficiency of research sequences, or rather shorten the results’ usage in practice using the GRID infrastructure. The EGEE integrates 70 research institutes from 27 countries in 12 confederations. To imagine the magnitude of the GRID, here is a worthy example: The world’s biggest atomic accelerator (called LHC – Large Hadron Collider) is being built in the swiss Cern. There will be 6000 scientists and engineers working in the center when it’ll be handed over in 2007.  More than 12-14 PetaByte of data is being collected a year just for the LHC experiments.  The storage and processing of such a huge database would need 200.000 computers.  Experts developed a complex system to handle this quantity of data. This system divides  2/3 of the data into geographically independent Regional Centers –Europe, Asia, America – and LHC integrates all of this into a whole.
