  Employing two state-of-the-art methods, second-order many-body perturbation
theory and multiconfiguration Dirac-Fock, highly accurate calculations are
performed for the lowest 318 fine-structure levels arising from the $2s^{2}
2p^{4}$, $2s 2p^{5}$, $2p^{6}$, $2s^{2} 2p^{3} 3l$, $2s 2p^{4} 3l$, $2p^{5}
3l$, and $2s^{2} 2p^{3} 4l$ configurations in O-like \mbox{Mo XXXV}. Complete
and consistent atomic data, including excitation energies, lifetimes,
wavelengths, and E1, E2, M1 line strengths, oscillator strengths, and
transition rates among these 318 levels are provided. Comparisons are made
between the present two data sets, as well as with other available experimental
and theoretical values. The present data are accurate enough for identification
and deblending of emission lines involving the $n=3,4$ levels and are also
useful for modeling and diagnosing fusion plasmas\kw{. These data can} be
considered as a benchmark for other calculations.
