I will discuss different procedures to infer stellar fundamental parameters, namely, the stellar mass, radius, and age, from the analysis of combinations of seismic and non-seismic data. Theperformance of these procedures will be illustrated through the presentation of results obtained for simulated and space-based data. In that context, I will also briefly discuss additional seismic diagnostics that are of interest in the context of the characterization of exoplanetary systems.
