  The achievement of the goals of the ongoing and future accelerator-based
neutrino experiments - notably the determination of CP violating phase in the
lepton sector - will require the development of advanced models of
neutrino-nucleus interactions. In this review, we summarise the present status
of experimental studies of neutrino-nucleus scattering, and discuss the
developments and perspectives of the theoretical approach based on
factorisation of the nuclear cross section, which has recently emerged as a
promising framework for the description of the variety of processes
contributing to the detected signals.
