Can someone direct me to a resource that gives insight or pointers on
the question of when it is better to use Access and when is it better
to use XL?
I presume you mean the spreadsheet software Excel?
If you want a database, use Access.
If you want a spreadsheet, use Excel.
As for the decision of whether a spreadsheet or a database application is more
appropriate for a specific business requirement, that takes some study and
understanding of what these two ways of handling data actually are. In short,
if you want to do dynamic calculations, sums and correlations, accounting-type
operations, an Excel spreadsheet would be indicated; if you have sets of
homogenous data that you want to enter, sort, report, and search, a database
like Access would be better. There are many cases where you want to do some of
both - and you *can* do sorting, searching, and handle lists of data in Excel,
and you can do calculations, sums, and accounting type operations in Access.
It's a question of emphasis - and you may well end up using both programs on
the same data.
