Error detection in data base systems
Michael M. Hammer · 1976
Incorrect data poses a serious impediment to the effective use of computerized data bases. Conventional approaches to the design and implementation of automated data error detection systems are inadequate for large and complex data bases. Partly, this derives from the inherent intricacy of the problem, with decisions being required as to what checks to perform, how and when to do the checking, and how to respond should an error be found; writing procedures to accomplish these functions is a difficult programming task. Also at fault is the unrealistic and overly simplistic view of data correctness embodied in most contemporary systems.
