  Often the pro­duc­ers of Big Data face the emerg­ing prob­lem of Data Del­uge. Nev­er­the­less ex­per­i­men­tal fa­cil­i­ties such as syn­chro­trons and free elec­tron lasers may have ad­di­tional re­quire­ments, mostly re­lated to the ne­ces­sity of man­ag­ing the ac­cess for thou­sands of sci­en­tists. A com­plete data life­cy­cle de­scribes the seam­less path that joins dis­tinct IT tasks such as ex­per­i­ment pro­posal man­age­ment, user ac­counts, data ac­qui­si­tion and analy­sis, archiv­ing, cat­a­logu­ing and re­mote ac­cess. This paper pre­sents the data life­cy­cle of the syn­chro­tron ELET­TRA and the free elec­tron laser FERMI. With the focus on data ac­cess, the Vir­tual Uni­fied Of­fice (VUO) is pre­sented. It is a core el­e­ment in sci­en­tific pro­posal man­age­ment, user in­for­ma­tion DB, sci­en­tific data over­sight and re­mote ac­cess. Even­tu­ally are dis­cussed re­cent de­vel­op­ments of the beam­line soft­ware, that holds the key role to data and meta­data ac­qui­si­tion but also re­quires in­te­gra­tion with the rest of the sys­tem com­po­nents in order to pro­vide data cat­a­loging, data archiv­ing and re­mote ac­cess. The scope of this paper is to dis­sem­i­nate the cur­rent sta­tus of a com­plete data life­cy­cle, dis­cuss key is­sues and hint on the fu­ture di­rec­tions.
