A database field such as MySQL's 'text' type (or 'long text') allows
a lot of flexibility in stuffing whole files into a database field.
Even 'varchar' is good for relatively short strings that vary in length.

Databases in general do not have an 'array' type for a field. An
array is typically represented in a table having columns for "which
array", "array subscript (for multidimensional arrays you may have
more than one column here)", and "value", and having one row for
each array element.

Rows, yes, databases would be useless if you can't put data in them.
Columns, yes, if you have privileges to alter the schema, but having
a dynamic schema is generally a very, very bad idea.

What's an "array package"? Are you referring to serialize() and
unserialize()? You can serialize() an array, store it in a database,
and fetch it later and unserialize() it to use it. However, you
can't generally have the database meaningfully look at what's inside
the serialize()d array.
