Definition of 'Record' Given the definition of 'record': &quot;a collection of field values for a given entity&quot;, is this a set of field values for ALL the fields of the entity, or only one particular field [so that you get a different set for each field]?
Also, is the relationship b/w a field &amp; field value essentially equivalent to a function?
NOTE: Total beginner learning data struc. &amp; algos.
All of the fields.  For instance, here is an example of a record:
{name: D.W., favoritecolor: blue}

You can think of a record as a function from field (key) to value.  For instance, the above would correspond to a function $f$ defined by $f(\text{name})=\text{D.W.}$, $f(\text{favoritecolor})=\text{blue}$.
