ThankYOU! (^.^)

No problem

iv. That mean data is arranged in ascending or descending orders before assignment of indexes? and is index same as keyfield?

v. In serial , is data scattered ?

iv. yes data is arranged in order according to the keyfield (keyfield is like the primary key) , index is not the same as the primary key it is just used for finding the data easier
INDEX is first, then comes all the data... for example: like for the bank account number(6 digit,etc), the index divides the number into 3 parts, the first index containing first 2 digits, the 2nd index containing the other 2 digits and the final index containing the last 2 digit then leading to main record AKA MAIN KEYFIELD in the MAIN file, so data is searched easily..

v. yes in serial, the data is in absolutely NO ORDER at all, all the data is scattered, every new data is added to the end of the file..

You have o explain the different types of test data that is normal, extreme and abnormal n give examples of each.
For example for the field number of hours abnormal data would be -15 or "A", so the system should not accept this data. if an error message is not produced then the limitation has to be identified . The validation routine will have to be designed again and corrected. simialrly for the other two data tests as well any example related to payroll .

thank you but can you answer completely of this question for me its 6 marks answer

indexed sequential is when records are not read one by one while they are being processed. they are stored in an order. you can directly go to the specific record you want
hierarchical database is one which is has a tree like structure and is not used any more because of one way relationship. it has few records or files on top and many below(branching out)
i have solved 6 pastpapers and questions come from indexed sequential and not hierarchical, just saying
