◦ Continuous aggregation and grouping
◦ CQL provides great flexibility for adjustments and declarative modifica-
tions
◦ Coherence provides some sort of consistent entity views; therefore, if we
fail, we can restart our analysis again without losing events
Surely, the presented implementation types (the second one is very schematic; please see
the Oracle documentation for details on implementation, http://docs.oracle.com/cd/
E14571_01/doc.1111/e14301/cache.htm ) are not the only ones possible in OFM. Coheren-
ce can be highly beneficial for caching Oracle DB data (as any data). Coherence also
provides a mechanism called CohQL to query the cache, SQL-style. In other words, we
have plenty of means to implement the data grid in our SOA infrastructure around all the
runtime frameworks with embedded tools for integration and data manipulation.
