  Nuclear equation of state (EoS) plays an important role in understanding the
formation of compact objects such as neutron stars and black holes. The true
nature of the EoS has been a matter of debate at any density range not only in
the nuclear physics but also in the astronomy and astrophysics. We have
constructed a database of EoSs by compiling data from the literature. Our
database contains the basic properties of the nuclear EoS of symmetric nuclear
matter and of pure neutron matter. It also includes the detailed information
about the theoretical models, for example the adopted methods and assumptions
in individual models. The novelty of the database is to consider new
experimental probes such as the symmetry energy, its slope relative to the
baryon density, and the incompressibility, which enables the users to check
their model dependences. We demonstrate the performance of the EOSDB through
the examinations of the model dependence among different nuclear EoSs. It is
reveled that some theoretical EoSs, which is commonly used in astrophysics, do
not satisfactorily agree with the experimental constraints.
