Following recent release of the largest catalog of X-ray sources ever created, built from the XMMNewton data and nicknamed 3XMM-DR5, the supporting website has been opened. For the first time it provides an intuitive search interface for the database of almost 400,000 X-ray sources and several advanced features for scientific analysis such as XSPEC-style spectral fitting of a vast collection of X-ray spectra right in a web browser. Built-in communication layer allows creation of flexible workflows to conveniently bring images, lightcurves and spectra of sets of X-ray objects together for detailed analysis with no pre-installed software required. The database also has handy connections to other X-ray archives and Virtual Observatory (VO) resources and contains precomputed cross-matches with common X-ray objects catalogs to facilitate easy comparison of (yet unstudied) objects of user interest with known CV, LMXB, HMXB, ULX, AGN and X-ray active stars. The innovative user interface is designed to make X-ray astronomy easily accessible even for researchers from other disciplines. The authors of this web application propose a tutorial aimed at highlighting the new research capabilities that are opened in X-ray astronomy by the efficient management of existing public data and also by software tools and archives interoperability. We will present several science use cases addressing important astrophysical problems such as search for elusive intermediate mass black holes, studies of populations of X-ray objects in our Galaxy and beyond – likely with quick-look discoveries to be made online. This tutorial may be interesting for the wide audience of researchers no matter of their background concerned with new efficient research methods, for software engineers willing to get familiar with new stack of technologies for quick look online analysis of complex data in astronomy, and for project managers needed to present source catalogs and other rich data to their project's research community.
