# MedeA’s Databases

Structure data and property data, both experimental and computed, provide vital information for materials formulation, preparation, characterization and lifetime performance. A common starting point for atomistic simulations is information about type and structure of a material. Often, this data is obtained from spectroscopic measurements such as x-ray powder diffraction (XRD) or neutron diffraction. With MedeA, the setup of atomistic models is straightforward and intuitive, as you can directly access experimental and calculated structure data gathered over decades.

## MedeA’s InfoMaticA

MedeA’s InfoMaticA query engine provides rapid access to structure data and related properties from the most comprehensive crystallographic structural databases: the Linus Pauling File (LPF), the Inorganic Crystal Structure Database (ICSD), the NIST Crystal Database (NCD), and the Crystallography Open Database (COD). Collectively, these experimental databases contain well over 1.1 million entries. In addition, MedeA’s InfomaticA lets you build up your own, searchable structure database using computed properties.

## MedeA ICSD

With MedeA ICSD, you have access to the structure database that is most frequently cited in literature. MedeA ICSD offers 199,000 records of experimental crystal structure information for non-organic compounds, including ceramics, minerals, and metallic systems. The integration of MedeA ICSD with MedeA’s Builders, Property Modules, and Compute Engines makes ICSD an indispensable resource for any solid-state materials research and engineering project.

## Materials Platform for Data Science (MPDS)

MPDS is the online edition of the Linus Pauling File (LPF), the most authoritative database of property information for inorganic materials available today. MPDS provides instant access to a comprehensive repository of phase diagrams, crystal structures, physical properties, and the corresponding literature references for inorganic materials. Directly import MPDS structure data in MedeA, and use as a starting point for simulations.
