MySQL and the forks in the road:

At the beginning of 2008 Sun Microsystems purchased MySQL AB, and ever since then there have been divisions in the ecosystem. As with any software community or ecosystem, where there are divisions there are usually forks, both in the community and the software itself.

MySQL history lesson.

When is “ACID” ACID? Rarely.

ACID and NewSQL databases rarely provide true ACID guarantees by default, if they are supported at all

Not even Oracle or DB2 provide full ACID (in distributed scenarios at least).

Updated Database Landscape Map

January 5th, 2013

Updated database landscape graphic:

I recently published an updated version but noted that there were a group of database vendors that had emerged in 2012 that didn’t easily fit into the segments we’d created.

It’s so much better… Good overview for anybody interested in understanding the DB world beyond just whatever one or two products or technologies they already know.

Oracle doing Hadoop and NoSQL

September 30th, 2011

Oracle docs show plans for Hadoop, NoSQL about the Oracle Loader for Hadoop, and Added Session: Big Data Appliance about Oracle’s Big Data Appliance.

And another one leaving the relational world for their DBaaS offering. It’s probably easier to manage as a service than Oracle…

Today SAP announced that they are using MongoDB as a core component of SAP’s platform-as-a-service (PaaS) offering. MongoDB was selected for the enterprise content management (ECM) section of the platform, as its flexibility and scalability will enable SAP to scale its content management service on its PaaS offering to meet customers’ requirements while managing data from different applications

Oracle Database Appliance

September 21st, 2011

Exadata Mini is the Oracle DB Appliance (ODBA?), as Oracle announced now.

It turns out that Oracle’s new small appliance isn’t really an Exadata Mini-Me. Rather, the Oracle Database Appliance is — well, it seems to be a box with an Oracle DBMS in it. Plus Oracle RAC and so on.

Focus on Big Data and Exadata Mini

September 19th, 2011

Oracle Openworld must be close, because the rumour mill starts heating up… Piper Jaffray is predicting that Oracle will release an Exadata Mini machine that will fit under ones desk (via DBMS2). And Jean-Pierre Dijcks compiled a list of Big Data related sessions at Openworld, Big Data may very well be the key note topic, I hear, so it’s worth spending some time at these sessions.
