  The theory of symmetry indicators has enabled database searches for
topological materials in normal conducting phases, which has led to several
encyclopedic topological material databases. To date, such a database for
topological superconductors is yet to be achieved because of the lack of
information about pairing symmetries of realistic materials. In this work,
sidestepping this issue, we tackle an alternative problem: the predictions of
topological and nodal superconductivity in materials for each single-valued
representation of point groups. Based on recently developed symmetry indicators
for superconductors, we provide comprehensive mappings from pairing symmetries
to topological or nodal superconducting nature for nonmagnetic materials listed
in Inorganic Crystal Structure Database. We quantitatively show that around
90\% of computed materials are topological or nodal superconductors when a
pairing that belongs to a one-dimensional nontrivial irrep of point groups is
assumed. When materials are representation-enforced nodal superconductors,
positions and shapes of the nodes are also identified. These data are
aggregated at \textit{Database of Topological and Nodal Supercoductors}. We
also provide a subroutine \textit{Topological Supercon}, which allows users to
examine the topological nature in the superconducting phase of any material
themselves by uploading the result of first-principles calculations as an
input. Our database and subroutine, when combined with experiments, will help
us understand the pairing mechanism and facilitate realizations of the
long-sought Majorana fermions promising for topological quantum computations.
