Query: Multi-Dimensional Event Data in Graph Databases   Process event data is usually stored either in a sequential process event log
or in a relational database. While the sequential, single-dimensional nature of
event logs aids querying for (sub)sequences of events based on temporal
relations such as "directly/eventually-follows", it does not support querying
multi-dimensional event data of multiple related entities. Relational databases
allow storing multi-dimensional event data but existing query languages do not
support querying for sequences or paths of events in terms of temporal
relations. In this paper, we propose a general data model for multi-dimensional
event data based on labeled property graphs that allows storing structural and
temporal relations in a single, integrated graph-based data structure in a
systematic way. We provide semantics for all concepts of our data model, and
generic queries for modeling event data over multiple entities that interact
synchronously and asynchronously . The queries allow for efficiently converting
large real-life event data sets into our data model and we provide 5 converted
data sets for further research. We show that typical and advanced queries for
retrieving and aggregating such multidimensional event data can be formulated
and executed efficiently in the existing query language Cypher, giving rise to
several new research questions. Specifically aggregation queries on our data
model enable process mining over multiple interrelated entities using
off-the-shelf technology.
