....language; further, relatively few attempts have been made towards using data mining techniques, e.g. association rules, in order to optimize queries semantically. The comparative analysis of relational and object oriented database systems is one of the most controversial database issues [CLC95, DD88] The efficiency of data storage and query execution is the main advantage of the relational systems; however the advocates of the object oriented world claim that their paradigm is more expressive. The vast experience of optimization techniques and index usage is a strong argument used by the ....

....base ConceptBase [JARK91] are reported in section 5. 3 2. Object Bases as Deductive Databases Most query optimization techniques have been developed for relational and deductive databases. On the other hand, the relational model has intrinsic weaknesses [JACK90] and performance comparisons [DD88] indicate that object oriented databases can beat their relational counterparts, esp. when following references. This section presents object bases to be special cases of deductive databases (EDB,IDB,IC) EDB is the extensional database of base relations, IDB is a set of deductive rules, and IC is ....

It is in these application domains that traditional RDBMSs suffer most from the impedance mismatch, and fail to deliver flexibility and performance [6]. In recent years several commercial OODBs have entered the marketplace. Since performance in CAD CAM or CASE applications has many faces, the OO7 benchmark was introduced as a yardstick for their success. It measures traversal , update and query evaluation performance for databases of ....

....Hypermodel requests both cold and warm times for each operation. 2.3 Other OODB Benchmarking Work There are several other OODB studies that are related to our work on OO7. Engineers at Ontologic used the initial Sun Benchmark to study the performance of Vbase, their first OODB product offering [DD88] Their reflections on the work provided a useful summary of some of that benchmark s shortcomings, including its lack of an opportunity for semantic object clustering (discussed further below) its very simple schema, and its lack of complex operations such as traversals. Also in this area, ....

The first result of this effort, which built upon the foundation laid by earlier OODBMS benchmarking efforts [CS92, RKC87, And90, DD88] was the single user OO7 benchmark [CDN93] This benchmark differed from its predecessors in that it This work was funded by Digital Equipment Corporation. This paper initially appeared in the proceedings of OOPSLA 94. 0 attempted to provide a truly comprehensive test of single user OODBMS ....

....plus caching to keep as much of the database in memory as possible. The results showed that for the small database, Rad Unify produced up to an order of magnitude better performance, whilst for the large database, the advantages of main memory residency and the other modifications were lost. Duhl Damon (1988) ported the benchmark to the Vbase object database system. They reported results only for the small database, but their findings did show that an object database could provide superior performance to a relational database based on a schema that was from the relational domain. Following experience ....

.... some criticism: Simple Data Model The data model is too simple to measure transitive closures and other traversal operations found in engineering applications (Anderson et al. 1990) Also, there are no metrics to measure the effects of type hierarchies, inheritance, or complex relationships (Duhl Damon 1988). Simple Operations Measuring simple operations is insufficient, as many engineering applications require support for higher level conceptual operations. For example, assessing the efficiency of transitive closures when clustering objects along some relationship, e.g. aggregation (Anderson et ....

Published OODB benchmarks and performance studies include [41, 42, 43, 44, 45, 46]. 1.2 Simplifying assumptions To study swizzling and obtain clear results, we focus on application behavior patterns most affected by swizzling, i.e. where swizzling is on the critical path. Consider a CAD design tool as an example. In an edit session the tool loads an existing design file (or ....

....database systems, since the field is relatively immature at this time. However, early testing of the Vbase object oriented database system has showed that its performance is as good as (and in some cases better than) the performance of popular relational database systems (INGRES and Unify) [19]. Considering that Vbase has not had time to be highly tuned and optimized, this result is impressive. Theoretically, one could expect superior performance from an object oriented database system since objects can be stored as is, rather than being flattened into several normalized relations. ....
