A few DBMS innovations: - The "No[t just ]SQL" movement brought us schema-free DBs (among other things; note that I personally prefer schema enforcement and strong typing); - CouchDB and others started to integrate MapReduce-style support for distributed processing; - Increased support for polygon/centroid indexing: PostgreSQL -> PostGIS, SQLite -> SpatiaLite - Graph databases: RedisGraph, SparkSee, Neo4j, AllegroGraph and others - as well as Cypher as a de-facto query language standard (supported by Neo4J, RedisGraph and others) Some senior DB people like Gerhard Weikum ( http://people.mpi-inf.mpg.de/~weikum/ http://people.mpi-inf.mpg.de/~weikum/ ) switched from databases to Web mining, because they believe that is where the action is now: acquiring/learning structured data from unstructured sources.
