File updating revisited
R.J. Lunbeck · Software Practice and Experience · 1986
Abstract Expositions of sequential master file updating are usually concerned only with insertions of new records, alterations or deletions of existing records and with the joint processing of these transactions. In actual practice other types of file transactions may also be needed, such as printing of (parts of) records, preventing possible alterations of certain records, etc. A general framework for dealing as well with such transactions in one processing run is presented. Simplifications of this framework are possible for random‐access files.
