English abstract:
Data integrity is one of the dependability attributes in
data-centric applications. However, applications exist, e.g.,
safety or mission critical systems, where availability is more
important for dependability than strict data integrity. Consequently,
in such systems availability can be increased by
temporarily relaxing data integrity. Potential inconsistencies
are accepted by constraint validation on replicated
copies, which are potentially stale in the face of network
partitions. Such consistency threats need to be bound and
eventually resolved during reconciliation.
The contribution of this paper is a solution approach to
this trade-off between availability and integrity by means of
explicit runtime-management of data integrity constraints
and consistency threats as well as reconciliation support.
