Conference Proceeding
Barclay, P. J., & Kennedy, J. (1994)
A conceptual language for querying object oriented data. In D. S. Bowers (Ed.), Directions in Databases: Proceedings [of the] 12th British National Conference on Databases, BNCOD 12, Guildford, United Kingdom, July 6-8, 1994 (187-204). https://doi.org/10.1007/3-540-58235-5_43
A variety of languages have been proposed for object oriented database systems in order to provide facilities for ad hoc querying. However, in order to model at the conceptual...
