maths functions and spreadsheet

[e-letter <inpost(at)gmail(dot)com>]

Readers,

I want to store data in a database. Do I have to perform mathematical
functions within the database, or can I use a spreadsheet (e.g. calc)?

For example:

spreadsheet with cells of a formula such as:

sum=((database 1 table 1, row 2 colum 3)*(spreadsheet cell
a1)/(database 2 table 2, row 3 column 4))-exp (spreadsheet cell b2))

Or must I perform all computations in the database and then create
some sort of report to display the results?

Yours,
