....these bounds are optimal. It is shown in [KRV] that answering 3 sided queries efficiently is key to solving the problem of indexing classes. Indexing classes is the natural generalization of indexing in the context of objectoriented databases and is very important to their good performance (see [KiL, ZdM] for more information on this area) KKD, LOL] present solutions to the problem of indexing classes. However, their algorithms are based on heuristics and cannot guarantee good worst case performance. Previous attempts to answer 3 sided queries in secondary memory by implementing priority search ....

....and design, multi media, or office automation not only requires efficiently managing large amounts of data, but also calls for a representational framework with sufficient expressive power to adequately model these applications. To this end, Object Oriented Database Systems (OODBMS) 2] [20] [25] 28] as well as Knowledge Base Management Systems (KBMS) 3] 24] 30] feature an object oriented knowledge model and an associated query language. In analogy to conventional database systems (DBMS) both types of systems can employ an algebraic approach for query processing [5] 31] 33] ....
....relationships) Fig. 2.1 shows an example hierarchy and the overall structure of one of the objects contained. In contrast to DBMS, KRISYS does not distinguish between schema information and instance information both is represented using the concept of objects (a similar approach is taken in [20]) Objects can therefore represent instances, classes, sets, elements, aggregates, etc. In addition to the above described concepts, the knowledge model of KRISYS provides various other features not usually found in object oriented models, as, e.g. integrity constraints and rules. For the scope ....

....Recently, object oriented database system (OODB) has become popular, because many advanced data intensive applications such as CAD CAM and multimedia data bases have employed this technique. Many papers have discussed about what object oriented means and what an object oriented database is[1][2][3] 4] A new transaction model for object oriented database system was proposed in paper [5] It is clear that object oriented databases have great potential to be used widely because of their object oriented design model and flexible data model. The lost update and the uncommitted dependency ....

....The size and complexity of CMTs make them hard to comprehend and maintain. In this paper, we address some of the problems of terminology comprehension by presenting a methodology for representing a CMT, modeled using the semantic network paradigm [15, 16, 17] as an object oriented database (OODB) [18, 19, 20]. We refer to such a representation as an Object Oriented Healthcare Terminology Repository (OOHTR) 21, 22] One of the most important components of the OOHTR is its schema, which provides an abstraction layer through which the CMT can be viewed and studied. This compact presentation of the CMT ....

....relationships. Given this fact, it may be hard for potential users and even a CV s own designers to orient themselves to the vast content of a CV and exploit its many advantages. In previous work, we have devised a novel technique for modeling a CV as an object oriented database (OODB) [2, 3, 5, 12, 17, 21, 34], a form we call an Object Oriented Vocabulary Repository (OOVR) 19, 20] Using our methodology, we have constructed OOVRs based on the MED and the InterMED [25] Both OOVRs are up and running in ONTOS DB Explorer [26, 31] a commercial OODB management system. Access to the InterMED OOVR is ....

....Healthcare Vocabulary Repository (OOHVR) a medical vocabulary implemented as an ONTOS database. 1 Introduction In this paper, we report on an experience of mapping a large controlled medical vocabulary based on a Semantic Network (SN) model [17] into an Object Oriented Database (OODB) system [2, 11, 18]. There are two major issues addressed in this work. The first issue is the proper way of modeling a vocabulary using the OODB paradigm. The second issue is the impact of the OODB modeling on the maintenance of the original vocabulary. This research was (partially) done under a cooperative ....

....(Brief definitions of these concepts will be given in Section 5.2. In general, the object oriented data model gives users flexibility and extensibility in 104 handling complex data. It was pointed out that the object oriented data model has a number of advantages over the relational data model [Gupt91, Kim89, Zdo90]. First, the objectoriented data model provides better modeling capability for representing real world data because data representations in object oriented databases do not have to be relational tables. In particular, an object oriented data model can represent relatively easily unstructured data, ....

....reuse research should be to establish a software engineering discipline based on such methodologies. Reusable software can best be accomplished with knowledge not only of what the software system is and what it does, but also why it was put together that way and why other approaches were discarded (Kim et al. 1989). The proposed framework will allow the conception, development and testing of a new methodology that adhere to a software development process, allow the recording and easy retrieval of valuable design rationale information and are able to record and present the knowledge gained during the ....

.... the 18th VLDB Conference Vancouver, British Columbia, Canada 1992 1 Introduction Object oriented languages and systems are becoming more and more popular for applications which model environments that lend themselves to extensive classifications, complex objects and inter object relationships [KLE89, Mey88, ZME90]. In a conventional object oriented database, the conceptual structure (schema) is embodied by a collection of abstract data types (called classes in this paper) which, when defined, are organized into an inheritance (ISA) hierarchy. Objects can then be created within classes, instantiating and ....

.... 1 an impedance mismatch [CoMa] Yet, the approach favored by previous researchers has been that of interfacing relational DBMSs to traditional languages [RIGEL, Sch77] More recently, major e#orts have been made to integrate databases and programming languages under the Object Oriented paradigm [KiLo]. These approaches tend to abandon relational databases in favor of an object oriented one often supporting a limited query capability and the navigational query style of pre relational systems. In contradistinction with these approaches, the LDL research has taken the viewpoint that full ....

....a requirements model, it is natural to think of implementing the system as a data base. Fortunately, high level database languages exist to provide the core behavioural framework onto which particular data structure, and associated functionality, can be built. Relational database languages (see [23, 74] for example) have the potential to provide a sound basis on which to implement complex software systems of persistent objects. 6.1.3 Implementation in an Object Oriented Environment: The Advantages Computational power is not an issue when choosing one implementation language over another, since ....

In the past there have been several attempts to establish relationships among the various families of class based formalisms (see Section 6 for a brief survey) The proposed solutions are not fully general and a formalism capturing both the modeling constructs and the reasoning techniques for ....

....be accomplished with O(log B n) I O s. Two important special cases of 2 dimensional range searching are 2 sided and 3 sided range searching (see Figure 1) 2 sided range searching can be used to index constraint databases [19,27] and 3 sided range searching to index object oriented databases [20,34]. The priority search tree can answer 3 sided queries (and therefore, 2 sided queries as well) in core in time O(logn t) using storage O(n) with a worst case update time of O(log n) Previous attempts to answer 2 and 3 sided queries in secondary memory by implementing priority search trees in ....
