Node.js and Oracle NoSQL Database

Oracle NoSQL Database is an interesting option to consider when you want a schemaless, fast, scale-able database which can provide relaxed (eventual) consistency. Oracle provides a Node.js driver for this database. In this blog I’ll describe how to install Oracle NoSQL database and how to connect to it from a Node.js application.

The Node.js driver provided by Oracle is currently in preview version 3.3.7. It uses NoSQL client version 12. (more...)

Graph Lookup in MongoDB 3.3

Specialized graph databases such as Neo4J specialize in traversing graphs of relationships – such as those you might find in a social network.  Many non-graph databases have been incorporating Graph Compute Engines to perform similar tasks.  In the MongoDB 3.3 release, we now have the ability to perform simple graph traversal using the $graphLookup aggregation framework function.  This will become a production feature in the 3.4 release.

The new feature (more...)

One more time: Do we still need Data Modeling?

After a short introduction of the main business drivers behind the new architectures and the panel by Arun Gupta, it was time for Mano Marks (more...)

How is data modeled in NoSQL?

The important thing to understand is the data does not change just because it is managed differently. If the data does not change, then the entities and the relationships contained in the data cannot change either. The entities and the relationships between them have not changed since the dawn of time. They were the same in the days of network database management systems which came before relational database management systems, they stayed the same when (more...)

Why should Oracle Database professionals care about NoSQL and where to start?

Oracle Corporation openly admits that NoSQL database management systems have the performance advantage over relational database management systems “when data access is ‘simple’ in nature and application demands exceed the volume or latency capability of traditional data management solutions.” Database professionals should therefore look seriously at NoSQL technology.(read more)

Oracle as the new IBM — has a long decline started?

When I find myself making the same observation fairly frequently, that’s a good impetus to write a post based on it. And so this post is based on the thought that there are many analogies between:

  • Oracle and the Oracle DBMS.
  • IBM and the IBM mainframe.

And when you look at things that way, Oracle seems to be swimming against the tide.

Drilling down, there are basically three things that can seriously threaten Oracle’s market (more...)

Readings in Database Systems

Mike Stonebraker and Larry Ellison have numerous things in common. If nothing else:

  • They’re both titanic figures in the database industry.
  • They both gave me testimonials on the home page of my business website.
  • They both have been known to use the present tense when the future tense would be more accurate. :)

I mention the latter because there’s a new edition of Readings in Database Systems, aka the Red Book, available online, courtesy of (more...)

Couchbase 4.0 and related subjects

I last wrote about Couchbase in November, 2012, around the time of Couchbase 2.0. One of the many new features I mentioned then was secondary indexing. Ravi Mayuram just checked in to tell me about Couchbase 4.0. One of the important new features he mentioned was what I think he said was Couchbase’s “first version” of secondary indexing. Obviously, I’m confused.

Now that you’re duly warned, let me remind you of aspects of (more...)
