What is difference between tuples and records?
Record is a complete row of data elements of one table, let say a student has a record under roll no. 3 in one table, where as tuple is a super set of record in which data belongs to other tables also, e.g. rows of records of student roll no.3 in other tables in relationship i.e. attendance, results, contacts, fees etc. So, that whole lot of data set of one student from all tables is tuple. As I know it. Thanks.
