Comparison to file access methods:
From the illustration above it should be clear that data manager is a lot fancier than the typical file access methods (indexed sequential files). File systems usually don’t support partitioned or parent-child sets. Several support the notion of record but none support the notions of field network or view. They in general lock at the granularity of a file rather than at the granularity of a record. File systems in general do recovery by taking periodic image dumps of the entire file. This doesn’t work well for a transaction environment or for very large files.
Generally data manager builds upon the operating system file system so that:
a) The operating system is accountable for device support.
b) The operating system utilities for import, export, allocation and accounting are useable.
c) The data is obtainable to programs outside of the data manager.
