Incremental Maintenance of


The materialisation of views is an important technique for increasing efficiency in distributed systems as well as in data warehousing systems. A materialised view has to be made up to date with respect to source data. To this end, either immediate propagation or deferred propagation can be applied. In this paper we propose an approach to maintaining materialised object–oriented views by using the deferred technique. In order to optimise the propagation of updates from source to view objects we use additional mapping structures and logs of operations. A log stores records describing operations performed on base objects.
