Subject Database

Creating and maintaining a subject database makes querying and reporting faster by automatically pre-populating input forms with identifying information — no need to re-type data.

How to Get Started

Sign into the NPDB and follow the steps in How to Create and Maintain a Subject Database. Once you create your subject database, transferring your existing records into it is easy, provided that your records are maintained in either a file format that can be converted to American Standard Code for Information Interchange (ASCII) fixed-width text or the Extensible Markup Language (XML) file format.


The XML import format offers numerous advantages over the fixed-width input format in transferring your in-house records to the NPDB subject database.
