MEDLINE database development process. In Step 1, the user loads the schema, creating empty tables in the database. In Step 2, the conversion software parses the XML files and either loads the data directly into the database (2a), or writes the data out to intermediate text files (2b). If intermediate text files are generated, data from those files are loaded into the database as a separate step in Step 3.
