A strong efiort is being made inorder to identify the physical processes involved, their relative role and theassociated time{scales.In this thesis we study the structural properties of galaxies in the localuniverse. Our study will serve as an ideal local zero point against which todiscern evolutionary trends out to high redshift and can be also used to testcompeting scenarios of galaxy formation and evolution.This analysis is performed using a magnitude limited sample of galaxiestaken from the Sloan Digital Sky Survey in 5 difierent photometric bands,from the near{UV to the near{IR.On all the galaxies in our sample an \eye ball" classiflcation has beenperformed and for many of these galaxies we have spectroscopic informa-tion. We measure the structural parameters which characterize the two pho-tometric components of galaxies, the bulge and the disk.
