The spreadsheet automatically does all the math for you.
Electronic spreadsheets are more convenient, because they are easier to edit. They also are easier to change cells and change information then paper based spreadsheets.
Manual or paper-based and electronic.
Because it gives much more room for people to create much larger spreadsheets that would take too much paper. That is one of the major advantages of an electronic spreadsheet. You can manipulate much larger amounts of data on an electronic spreadsheet. This makes them far more useful. There is so much that can be done on a large electronic spreadsheet that would be very difficult to do on a paper-based one.
The data relational model is to do with databases. While you can do databases with a spreadsheet, it is limited compared to a standard database product and it is difficult to implement the relational model effectively. Relational databases use tables that are connected to each other. Spreadsheets lay out data in tabular form and it is possible to have relations between separate tables, but not in the way that it is done in a database. A database sets up a table in a more specialised format and only holds the data it needs. A spreadsheet would have a table in it, but it would not be the complete spreadsheet as you would have lots of unused cells in the spreadsheet. So you would not normally implement a relational database in a spreadsheet.
It is easier to use a spreadsheet than a pen and paper because with a spreadsheet, mistakes can easily be corrected by canceling and repeating. Spreadsheets also carry out automatic scientific calculations such as mode, median and standard deviation.
A spreadsheet can be a paper-based document. Excel is an electronic spreadsheet. A spreadsheet can refer to any electronic spreadsheet program. Excel is just one of the electronic spreadsheet programs that are available and it is the most popular one.
You can work out calculations much faster on a spreadsheet and you can use formulas to work out your answers properly instead of doing it in your head or on pen and paper which is easier.
Because that is exactly what it is. It provides to facilities to create spreadsheets on your computer. It has all you need to do that. It is layed out like a paper-based spreadsheet and like other electronic spreadsheet programs.
They are based on the accountant's paper-based spreadsheet, which consists of rows and columns into which values can be put and calculations can be done. The electronic spreadsheet enables the calculations to be done automatically and provides a whole host of other features that a paper-based spreadsheet can never achieve.
when we use computerised database it really makes our calculation easier and quick rather using pencil and paper. it reduce the time that takes to use in paper and it makes our work easier and comfortable so we can easily make calculations in microsoft spreadsheet.
They either used other spreadsheet applications, or calculators or paper. Excel was not the first electronic spreadsheet. Excel came out in 1985, but the first electronic spreadsheet was VisiCalc, which came out in 1979. There were others between VisiCalc and Excel, most notably Lotus 1-2-3.
The first major spreadsheet that Microsoft had was called Multiplan. It had a code name EP, standing for Electronic Paper. It preceded Windows and it preceded Excel.
