A problem in querying recursive patterns with OQL (2002)
Preprint / Working Paper
Raguenaud, C., Kennedy, J., & Barclay, P. J. A problem in querying recursive patterns with OQL

This paper analyses the problem generated by recursive patterns in typed query languages such as OQL [Cattell '97]. Recursive patterns describe hierarchical structures such as those defining classifications or part-explosion problems. A classificatio...
