Oh … snips and snails and puppy dog tails – that’s what databases are made out of … OK, so they’re not.  Databases are also referred to as files or datafiles.  Sometimes a databases is split into subfiles, but not necessarily.  The ERIC database is a good example of a database that is split into two subfiles – the Current Index to Journals in Educations (CIJE) and Resources in Education (RIE).  The important thing to remember is that some databases will have subfiles and some won’t.  When they exist, they can sometimes be helpful to craft a search strategy.  All databases will be made up of database records.  Each database record is made up of fields.  Sometimes fields are divided into subfields.  Perhaps an example will help.
