....applications due to the imprecise specification of the standard and the heterogeneous interpretations of ODMG vendors. For developing pure generic applications, a number of additional features are required. Such a discussion is outside the scope of this paper but is discussed in [Roantree and Subieta, 200#]wherepossible solutions and improvements to the standard are o#ered. 3.2 Metadata Query Samples In this section, we demonstrate why the language was developed by illustrating a series of metadata queries using conventional OQL, and demonstrate how these queries might be simplified using an ....
....to the ODMG metamodel: virtual metaclasses need contain only mapping information to base (or virtual) metaclasses; yet virtual subschemata must contain enough information for high level graphical tools to browse and display virtual types. This has been well documented in the past: for example [Subieta, #996] stating that modern database systems require a richer means of queryingdatathanthato#ered by simple ASCIIbased query editors. A prototype system was built using Visual C 6.0 for the Versant O O database running on NT platforms. It is assumed that client applications may be either software ....

.... and the OQL query language that supports interactive and embedded declarative access modes in a functional style, new modes of interaction with ODMG compliant databases are being investigated in the fields of visual query languages [7, 13] and computationally complete query language extensions [17]. In this paper we report on the use of the deductive paradigm for querying ODMG databases through DOQL. DOQL is a rule based database query language that provides a deductive interface to an ODMG compliant object database. DOQL is designed to integrate object oriented and deductive language ....
