nosql database: All content tagged as nosql database in NoSQL databases and polyglot persistence
The Amazon team released a whitepaper comparing the total cost of ownership for 3 scenarios:
- on-premise NoSQL database
- NoSQL database deployed on Amazon EC2 and Amazon EBS
- Amazon DynamoDB
As you can imagine DynamoDB comes out as the most cost-effective solution (79% more effective than on-premise NoSQL database and 61% more cost-effective than AWS hosted NoSQL database). Read or download the paper after the break.
Jeff Darcy has written a while back about the (lack of) security in NoSQL database. Unfortunately things haven’t changed much and if you check the NoSQL + Node.js applications I’ve posted lately you’ll notice that some of them are completely ignoring security.
And there are some people realizing the risks and starting to express their concerns:
Playing with MongoDB lately, I’m getting scared. Because I’m seeing some really bad practices out there. Seeing it in live code. In tutorials.
Because of this, defenses against SSJS injection are also similar to SQL injection defenses:
- Validate user input used in SSJS commands with regular expressions.
Remember there’s no such thing as security through obscurity.
It didn’t take long for IBM to follow Oracle’s foray into the NoSQL space by announcing that IBM DB2 and Informix will include NoSQL features.
So, we actually took one of these NoSQL triplestores from the open source [community and] we modified it to sit on top of DB2 so that it can use DB2’s indexing, DB2’s logging, DB2’s solution for high availability [and] and all the things you would expect.
Reports are not very clear yet, but it seems that DB2 NoSQLish features are based on IBM’s Rational Jazz tripplestore solution—an approach similar to Oracle’s NoSQL Database 11G which is based on Oracle’s BerkleyDB Java Edition.
When speculating about Oracle’s future in the NoSQL market I was writing that I expect Oracle to extend the support for NoSQLish interfaces to its core database products. And it looks like IBM is taking exactly this route:
Curt Cotner: “All of the DB2 and IBM Informix customers will have access to that and it will be part of your existing stack and you won’t have to pay extra for it. We’ll put that into our database products because we think that this is [something] that people want from their application programming experience, and it makes sense to put it natively inside of DB2.”
Looking back at these events (Oracle’s NoSQL database, Oracle Big Data appliance, IBM DB2 and Informix supporting NoSQL features), makes me think if and how are these related to the new Enterprise NoSQL trend I’ve mentioned earlier.

There’s been a lot of speculation about the announcements coming from Oracle’s OpenWorld event. A first part was revealed during the keynote in the form of an in-memory analytics appliance called Exalytics . But there’s talk about a Big Data Appliance and an Oracle NoSQL database.
Here’re my predictions
Oracle became very aggressive in selling products based on hardware, software, and services. So they’ll announce a Hadoop appliance integrated with an existing Oracle product. It could be either the Oracle Exadata or even the newly announced Exalytics.
This appliance will place Oracle in competition with all other Hadoop appliance sellers: EMC, NetApp, IBM. Also these days most of the analytics databases try to integrate with Hadoop.
Oracle already has a couple of non-relational solutions in their portfolio: BerkleyDB, TimesTen, Coherence. And they’ve already started to test the NoSQL market by announcing the MySQL and MySQL Cluster NoSQL hybrid systems.
I don’t expect Oracle NoSQL database to be a new product. Just a rebranding or repackaging of one of the above mentioned ones. Probably the TimesTen.
Oracle will invest more into integrating its line of products with Hadoop. Having both a Hadoop and an in-memory analytics appliance will make them very competitive in this space.
Oracle will extend the support for NoSQLish interfaces (memcached) to its other database products.
What are your predictions?
