What is the basic requirement in any computerized business application?

Data input

The correct answer is option 2- Data input.

Data input is the basic requirement in any computerized business application.

In any computerised business application, the basic requirement is to input data; which may be either for processing parameters e.g. input of data parameters such as month number and name of the month or number of working days, DA%, etc. for the processing of payroll of the company or to update various data elements. In both the cases data should be correct, accurate and should be in proper format. This means that data should be validated, corrected and can be display in proper format. By default in spreadsheet the numbers are right aligned and texts are left aligned. The spreadsheet can distinguish different types of numbers; recognise a date, a currency, or a percentage value or text etc. For example, if we type 16/04/1980 in a cell, spreadsheet will recognise it as a date and act accordingly. The software processes the data and generates the output; which should be in specific format. For example 1.5 might represent a value for one and half teaspoon in one spreadsheet while the same 1.5 would represent constant multiplier for age in another spreadsheet etc.
