Abstract: In contrast to three schema levels in centralized objectbases, a reference architecture for federated objectbase systems proposes five levels of schemata. This paper investigates the fundamental mechanisms to be provided by an object model to realize the processors transforming between these levels. The first process is schema extension, which gives the possibility to define views. The second process is schema filtering, that allows to define subschemata. The third one, schema composition,...

...It turned out that the availability of meta objects is extremely useful in this context, too. This idea is developed even further in [TS93] where complete schema transformation processors for federated objectbases are identified that also make use of meta information. We...
...of two steps: 1) identification of redundancy and (2) consistency control of the identified redundancies. Based on our previous work [16, 19], we present two mechanisms to identify redundancy: schema integration and object integration. Afterwards, we mention some techniques...
