Postgres Advances to Meet NoSQL Challenges
Most Postgres users don't need NoSQL. With new features and capabilities alongside several longstanding components and extensions, Postgres can support virtually all of today’s data types as well as unstructured and semi-structured data. This means Postgres can power many applications written for NoSQL technologies and developers can build applications in Postgres that achieve the same results as NoSQL solutions.
This white paper explains some of the operational challenges presented by the use of NoSQL technologies, and how JSON and HStore in Postgres lets you build document databases and key-value stores within Postgres.
