Abstract: A method and apparatus for providing access to object data stored in an object server in response to a database query. The method comprises the steps of receiving a database query comprising a relational operation with a data surrogate identifying object data stored in an object server, transforming the database query into relational database commands, transmitting the relational database commands to the relational database management system, receiving a response table from the relational database management system, compiling an answer set from the response table comprising an object locator responsive to the database query, and transmitting the answer set to the client.

Abstract: A database system carries out a technique for use in delivering data of a user-defined type to a requesting system. The system first receives a request from the requesting system for data of the user-defined type. The system then identifies a storage location for the requested data, as well as a storage location for program code designed to allow manipulation of the requested data on the requesting system. The system then retrieves both the requested data and the program code from their respective storage locations and delivers both the requested data and the program code to the requesting system.
Abstract translation: 数据库系统执行用于将用户定义类型的数据传送到请求系统的技术。 系统首先从请求系统接收用户定义类型的数据的请求。 然后，系统识别所请求数据的存储位置，以及用于允许在请求系统上操纵所请求的数据的程序代码的存储位置。 系统然后从其各自的存储位置检索所请求的数据和程序代码，并将所请求的数据和程序代码传送给请求系统。
