If you don't know the difference, then what you doing is almost
certainly a simple "flat-file" database.
A "flat-file" database is basically a box data cards. For example, an
address book would be one record for each different person with their
phone numbers, email address, etc. all stored together.
The other type of database is "relational". That has parent and child
records, often in separate database structures, linked by a common data
item. For example, a business might have five company cars and each car
has separate related records for each individual workshop service. You
can often create small relational-like databases using a flat-file
database system by using duplicate fields, but it is messy and
cumbersome, and can waste a lot of storage space.
