I will briefly review main structural properties of edge-on galaxies which can be derived via photometric decomposition analysis and radiative transfer modeling of galaxies. I use observations in a wide domain of wavelengths (from UV to far-infrared and submm wavelengths) in which stellar and dust properties can be broadly studied. I consider edge-on galaxies of different morphology: from early to late-type spirals, including peculiar galaxies with polar rings and polar bulges and galaxies with different structural features (disc warps and truncations, LSB details, boxy/peanut-shape bulges and galaxies with very thin discs). The new software pipeline DECA for performing automated and manual decompositions and estimating structural parameters of galaxies has been designed and used in this study. DECA provides new capabilities to investigate large samples of galaxies and obtain their general structural characteristics as well as to carry out a detailed analysis of various galaxy features. I will discuss some famous galaxy scaling relations with an attempt to link them to galaxy formation and evolution.
