Databases consist of records.  If you think about a library catalog, each book in the database is represented by an individual record.  Each record consists of fields.  In a library catalog record, these fields provide information about a particular book.  Examples of fields would be the author, the title, and the subject headings.  Fields can be searched.  In a periodical database there would be one record for each article indexed by the database.  The record of a periodical database would consist of fields like the periodical title (sometimes referred to as the source), the article title,  and the author. Below is an image of a record from a periodical database.  The left column shaded in yellow describes the parts of the record.
 

The highlighted items
are all examples of fields. 

Most fields in a database
can be searched.
