Q1. What is your current product offering?

Brian Bulkowski: Aerospike is the first in-memory NoSQL database optimized for flash or solid state drives (SSDs).
In-memory for speed and NoSQL for scale. Our approach to memory is unique – we have built our own file system to access …

There was once a big hooplah about the MySQL Storage Engine Architecture and how it was easy to just slot in some other method of storage instead of the provided ones. Over the years I’ve repeatedly mentioned how this wasn’t really …

One of the most complicated aspects of putting together our database landscape map was dealing with the growing number of (particularly NoSQL) databases that refuse to be pigeon-holed in any of the primary databases categories.

I have begun to refer to these as “multi-model databases” in recognition of the fact that they are able to take on the characteristics of multiple databases. In truth though there are probably two different groups of products that could be considered “multi-model”:

True multi-model databases that have been designed specifically to serve multiple data models and use-cases

Examples include:
FoundationDB, which is being designed to support ACID and NoSQL, but more to the point …

Brief pause of that Sudoku series :  I’m working on my object-relational mapping framework code-named Eth.

It’s vaguely similar to Glorp but much simpler and not as intelligent as Glorp.  This time, the resurrection of my framework is more like… a rewrite from scratch.  It all started on VAST, then I ported it to Dolphin then Squeak and now Pharo.  Hopefully, now I will spend more time writing it than porting it! Also, it will exclusively support Pharo.  I also decided to write some SUnit tests to make sure I can properly handle PostgreSQL, MySQL and Interbase for the first version.  But I am also planning on supporting SQL Server, Oracle, DB2, Access and Firebird.  Eventually!

Besides, I’m also …
