primary key - correct answer ✔a field in a database that uniquely identify
each record so that it can be retrieved, updated, and sorted.


secondary key - correct answer ✔a field that has some identifying
information, but typically does not identify the record with complete accuracy

uniquely identifies a row of another table. It is used to establish and enforce a
link between two tables.

multiple columns and multiple rows


database - correct answer ✔logical grouping of related data files (aka
database tables).


database management system (DBMS) - correct answer ✔a set of programs
that provide users with tools to create and manage a database.


data security - correct answer ✔Because data are "put in one place" in
databases, there is a risk of losing a lot of data at one time. Therefore,
