The PDF-4 family of databases is designed to provide users with continuously updated data from global resources. For several years, the ICDD has been processing over 50,000 new material data sets every year. These are sourced from international database organizations, private contributions, donations, grants and bibliographic literature
The PDF-4 family of databases is designed to provide flexibility. This flexibility is demonstrated in our data mining, search, and graphics capabilities, as well as our display fields. Reference data can be represented as X-ray, neutron, synchrotron, or electron diffraction. Data can be viewed and displayed as traditional diffraction patterns (2 theta versus intensity) or two-dimensional plots (xy versus intensity), as either spot patterns or ring patterns, or as electron diffraction back scattered patterns
It's a single, affordable program that has all the power of the Microsoft Project
