Operational Data Hub
Although bias to Marklogic, “Decimating Data Silos With Multi-Model Databases” provides an interesting. Few interesting take aways:
60 percent of the cost of a new data warehousing project is allocated to ETL and corporations spend $36 billion annually on creating relational data silos.
Of no surprise is the “semantic metadata” concept, and also the callout to ELT over ETL.
Three approaches to avoiding ETL hell:
- A semantics triple store/graph-only architecture
- A document store-only architecture
- A multi-model approach that combines a document store and triple store
On Option 2, “Defensive programming for unexpected data structures” is so true based on what I’ve seen
Agree that Option 3 is the preference, and best of both worlds (document storage and ontology). Not being a Marklogic expert is about appear in many ways that this is similar to combining MongoDB or similar with D2RQ?
