The advent of new and more sensitive surveys providing photometry at many wavelength ranges and covering large sky areas (GALEX, SDSS,2MASS, UKIDSS, AKARI, WISE), is pushing astronomy towards a change ofparadigm where small groups, and not only large consortia, need to analyze large multi-wavelength data sets as part of their everydaywork. In this context, the Virtual Observatory (VO), as a common frameto exchange not only observational data but also theoretical models,plays a very important role.

In the talk I will provide some further motivation on the need offrame works as the Virtual Observatory and will describe some of themost commonly used VO-tools including a "life" demo of capabilities ofsome of these tools.
