....of objectoriented databases and their query optimizers. We propose the stack based approach to query languages as an adequate framework aiming at the same goals. 1 Introduction Object algebras are proposed as tools to formalise object oriented databases and their query languages (QLs) see [AbFi95, AlAr93, BaWi94, CDV88, Clue89, ClDe92, ClDe94, DGG94, GZC89, HFLP89, KeMa94, LMSVVZ93, Liu93, PoSm94, ShZd89a, ShZd89b, ShZd90, StOz90, SZLV93, SLVZ95, VaDe91], and many others. They are claimed to be well suited to solve query optimisation problems. In this paper we carry out a critical analysis of this research activity. There are two principal reasons motivating our work. First, we see in these algebras severe flaws, which cause doubts concerning ....
