Answer to Question 1

TRUE

Answer to Question 2

Databases that carry their data in the form of tables and that represent relationships
using foreign keys are called relational databases. Foreign keys are columns that are keys of a
different table than the one in which they reside. The relational model was the single, standard
way of processing databases for over thirty years. Recently, however, new styles of database
processing have started appearing. Part of the reason is that the major principles of the relational
modelfixed-sized tables, representing relationships with foreign keys, and the theory of
normalization came about because of limited storage space and limited processing speeds back in
the 1960s and early 1970s. At some point, maybe the mid-1990s, these limitations were removed
by improved storage and processing technology and today they do not exist. In other words, the
relational model is not needed today. Other reasons for the development of nonrelational
databases include the need to gain faster performance using many servers and to store new types
of data such as images, audio, and videos.
