Record-at-a-Time Processing
Record-at-a-time is a method in DBMS that processes one record or on row from a file or table at a time. This means Record-at-a-time processes only one record from the table at a time and it performs all the operations or computation on that record. After computing that record it moves to the next record in the table and it will continue until all the records are processed. This method is very beneficial when there is a large dataset which not fit in memory.
The concept of Record-at-a-time in DBMS is not a feature of DBMS but it is a way of data processing in a relational database.
