Question
What is the purpose of relative record data set used in VSAM?
Answers
This is the data set in which records are identified and accessed by a specific number of records that are relative to the first record in the dataset. It allows the accessing to be performed in randcom order and it also has only one component that is data component that can be used to keep the data in a linear manner. This method only supports fixed length records. This record is specified before any accessing of the list of record can be performed. The maximum number of records that can be contained in the dataset depends on the record posisiton of the data. It has both sequential and random accessing of the records and provides clustering of the data. This helps in maintaining the disk records that can be used later in maintainance of the data sets.   Your Comment
