  We introduce a computational database with calculated structural,
thermodynamic, electronic, magnetic, and optical properties of 820
one-dimensional materials. The materials are systematically selected and
exfoliated from experimental databases of crystal structures based on a
dimensionality scoring parameter. The database is furthermore expanded by
chemical element substitution in the materials. The materials are investigated
in both their bulk form and as isolated one-dimensional components. We discuss
the methodology behind the database, give an overview of some of the calculated
properties, and look at patterns and correlations in the data. The database is
furthermore applied in computational screening to identify materials, which
could exhibit Majorana bound states.
