Spreadsheet
A spreadsheet is an interactive computer
application program for organization and analysis
of data in tabular form. Spreadsheets developed
as computerized simulations of paper accounting
worksheets.
The program operates on data represented as
cells of an array, organized in rows and columns.
Each cell of the array is a model–view–controller
element that can contain either numeric or text
data, or the results of formulas that automatically
calculate and display a value based on the
contents of other cells.

Spreadsheet (2)
A modern spreadsheet file consists of multiple
worksheets (usually called by the shorter name
sheets) that make up one workbook, with each
file being one workbook. A cell on one sheet is
capable of referencing cells on other, different
sheets, whether within the same workbook or
even, in some cases, in different workbooks.
Spreadsheets share many principles and traits of
databases, but spreadsheets and databases are
not the same thing. A spreadsheet is essentially
just one table, whereas a database is a collection
of many tables with machine-readable semantic
relationships between them.
