"Databases are implementation details! Considering the database should
be deferred as long as possible. Far too many applications are
inextricably tied to their databases because they were designed with
the database in mind from the beginning. Remember the definition of
abstraction: the amplification of the essential and the elimination of
the irrelevant. The database is irrelevant at this stage of the
project; it is merely a technique used for storing and accessing data,
nothing more." (Robert C. Martin, Agile Software Development, p. 194)
