DATA and INFORMATION DATA -raw numbers, words INFORMATION – data that has been turned into something we can understand

Entry of data into a system (computer system – shop, bank etc.) Bar Codes OCR – scanning to get text documents into file MICR Direct Data Entry Validation Verification MARKED SENSE CARDS – like the lottery SWIPE CARDS (magnetic stripe cards)

INFORMATION COLLECTION DATA PREPARATION INPUT OF DATA PROCESSING DATA STORAGE OF DATA OUTPUT OF DATA/INFO Gather lottery card Fill card in Insert at Co- op till Find out winner –check ticket! Save amount in bank Print out winners DATA PROCESSING CYCLE

Validating RANGE CHECK By two people - expensive Or like the times on internet pages when you enter your password twice Type in a day of a date – has to be in the RANGE 1 to 31 Validating LENGTH CHECK Type in a post code – has to be of LENGTH 8 characters DATA CHECKING Validating – the program checks for you Validating CHECK DIGIT The digit at the end should match up with those at the beginning Verification – enter the data twice

MANAGEMENT INFORMATION The manager has extra information about the business e.g. how fast the workers are working Which stock is moving fast Which things might sell faster

Transaction Files and Master Files Remember Tape is sequential Access Disk is Direct/Random

Computer crime DATA PROTECTION ACT -Data Subject -Data User -Data must be collected legally -User can check data COMPUTER MISUSE ACT Viruses Hacking COPYRIGHT ACT
