A field is a sector of a record that has one type of information in it.  
Such as text, Integer, long integer, Date, and so on.  A record is a 
group of fields. A bunch of records make up a File or database in the 
case of a flatfile.  

The difference between a flat file and relational database is that in a 
relational database you can have different types of records in 
different files, but  a Record also has to include one field that is 
common to the other types of records.  That field is called a key.  
Those other records may have entirely different information except for 
the Key.  So one record may be "Perrys Books" and another record 
"Perrys cash flow".  Then the primary key field in both records could 
be "MoneySpentOnBooks".  So one Flatfile has a relationship with 
another flatfile and that relationship in this case is 
"MoneySpentOnBooks".  

It can and often does get a lot more complex than that with really 
powerful databases but that's where the Structured Query Language comes 
in, being able to create quite complex structured queries to generate 
data that use those relationships between files.  So for instance in 
our fictitious "Perrys database" you could structure a query that would 
tell you that you've overspent on books this month.  :)

That's a really basic explanation, like saying the Human body is made of 
single celled animals with a nucleus and by getting a whole pile of 
these cells to interact a person can walk.

Get in and throw things at it Perry, If you can handle a flatfile you're 
a good step of the way there.  Heck, my first steps in a Database were 
in PFS First Choice .   :)  Then give us the feedback.
