1- Data :
- Data represents the basic facts about an establishment
- Data collection or capture is an essentile activity
- Data verifcation should be performed before iserting the data into the database
- Data elements are grouped in a record
- records are grouped in a table
- Database consis of a number or tables
Data... data is raw. It simply exists and has no significance beyond its existence (in and of itself). It can exist in any form, usable or not. It does not have meaning of itself. In computer parlance, a spreadsheet generally starts out by holding data.
2- information :
it is processed data to satisfy the needs of :
- users
- management personnel
- Data analysts
Information... information is data that has been given meaning by way of relational connection. This "meaning" can be useful, but does not have to be. In computer parlance, a relational database makes information from the data stored within it.
