Abstract

The design of an extensible system, called the object shell, to define and query an object-oriented view of an existing database is described. An object-oriented view is defined by identifying the object types and the functions between them that are present in the existing database. The object shell provides facilities to declaratively define the logical schema, implementation methods for functions, the cost associated with the implementation methods, and the query optimization knowledge. An implementation method is a sequence of access routine calls. Access routines are defined by the database administrator (DBA), and each of them encodes the detailed knowledge to access a single physical structure (e.g., a file). The query interface of the object shell allows the user to issue queries against the view. The object shell translates the user query into an efficient program that calls the access routines to retrieve the required data.
