The document discusses the convergence of SQL, NoSQL and Hadoop technologies. It notes that these were originally separated but are now joining together. Analytics problems now span these different platforms, and many platforms now support multiple data workloads and personas. However, challenges remain around common security, federated querying, and workload management across platforms. The ideal solution would be a logical hub to coordinate these functions consistently across platforms.

Analytics problems cross silos –
Operational examples
 Customer engagement
 Interaction – Customer 360 query in DW
 Behavior – Enrich with sentiment analysis on Hadoop
 Engagement – Manage real-time engagement on NoSQL
database
 Risk mitigation
 Baseline – Model party & transactional risk on DW or
Hadoop
 Enrich – Analyze, rank impact of externalities on Hadoop
 Ingest – Real-time market feeds via streaming in-memory
 Define – Decision processes offline via BPM
 Act – Allow/deny credit on system of record

Architecture –
Common threads
 Aggressive tiering
 Multiple storage engines
 Multiple workload types
 On the horizon:
 Federated query
 Workload/query orchestration
 Loose ends:
 Common security?

SQL Databases adding multiple personas
 IBM DB2
 BLU architecture adds columnar, data skipping, advanced tiering
 New MongoDB-compliant JSON data store
 Oracle Database 12c
 “In-Memory” option adds DRAM-based columnar, extreme compression
 Microsoft SQL Server
 PDW adds columnar indexing
 PolyBase feature adds Hadoop integration
 Teradata
 Teradata 14.10 adds “Intelligent Memory” data tiering, columnar, Hadoop integration
 Aster 6 adds graph, file store, “SNAP” framework for choreographing SQL, MapReduce, graph
& Hadoop processing
 SAP
 “Smart Data Access” federated query over HANA, Sybase IQ, Teradata & Hadoop

Hadoop growing beyond MapReduce
 Apache Hadoop 2.0’s new YARN resource allocation framework allows
multiple workloads
 Interactive SQL – lots of flavors
 Spark – The new MapReduce & more…
 Search
 Streaming
 Loose ends:
 Graph ready for prime time?

13. © Copyright Ovum. All rights reserved. Ovum is an Informa business.13
Emerging NewSQL + NoSQL databases
 JSON data stores exploding
 Intuitive for representing Internet data
 MongoDB, Couchbase
 IBM, Teradata… potentially Oracle adding JSON
 New transaction stores … not full ACID
 Cassandra for NoSQL (integrated to Hadoop)
 NuoDB, Clustrix, MemSQL & others reinvent OLTP for
distributed Internet apps
 HBase
 DynamoDB, Berkeley DB (Oracle NoSQL database) &
other key-value stores

Loose ends
 Ideally, policy-based federated
query will be the solution
 Who owns federated query?
 Data platform?
 BI tool?
 Application?
 Who owns workload management?
 Who owns security?
Tug of war between data platforms likely

Takeaways
 Analytics no longer limited by platform constraints
 Data platforms are taking multiple personas –
 Platform choice is not either/or
 But
 Analytics are no longer silo’ed
 Execution remains silo’ed
 The brass ring will be a logical hub for
 Policy/SLA-based workload targeting & management
 Security & operations/performance management
