I will present a large unified database of over a million radio objects detected at 6, 20, and 92 cm, as well as at optical wavelengths. The main scientific motivation behind this project is a test of the AGN unification paradigm based on a comparison of observed populations with mock catalogs created using different models of cosmological AGN evolution. The contributing surveys are FIRST and NVSS (both 20 cm), WENSS (92 cm), GB6 (6 cm) and the SDSS (optical). Our preliminary analysis focuses on a 3000 square-degree sky region where all the contributing surveys overlap. An automated morphology classification scheme defines nine radio-optical classes of objects, and I will describe the distributions of those classes in radio and optical morphology-flux-spectral slope diagrams. I will also discuss the behavior of optical quasar spectra as a function of their radio morphology.
