The aim of this paper consists in defining an algebra allowing the request of structured documents in the context of object oriented approach. The operators of this algebra are defined in conformity with the concepts of the object model. It takes into consideration not only the embedding of structures and links between them, but also the informational aspect of the document as well as its structural aspect. The operands of the proposed algebra are only one type: they are subdatabases. A subdatabase is made of a collection of the databases objects, grouped in classes and interconnected through links. This algebra responds to two objectives. Firstly, it represents a basic nucleus of a declarative query system; it contains the whole of the elementary operations which will be used in the resolution of the request. Secondly, it provides facilities to users to formulate their requests and manipulate the documentary database.
