Over the past few years I’ve seen the emergence of polyglot persistence i.e. using different data storage technologies for different data and in most situations we work that out up front. The main down side to this approach is that we now have to keep two data sources in sync but it’s interesting to think about whether this trade off is worthwhile...
Here's a real quick video of the war between SQL and NoSQL methodologies.

As mentioned, the data in LMDB is actually stored in page. And I am currently tracking through the process in which we add a new item to the database.
Graph ranking algorithms are all about mapping a complex graphical structure to a numeric vector. For a given algorithm, a single numeric value in the resultant vector corresponds . . .

MongoDB is an open source document-oriented NoSQL database system which stores data as JSON-like documents with dynamic schemas.
The NoSQL moniker that was coined circa 2009 marked a move from the “traditional” relational model . . .
So, our managed implementation of leveldb is just about ready to go out and socialize. Note that those are just for a relatively short duration, but they give us good indicator of where we are.

This session starts of by describing why we now have many different approaches to storing data and how to identify use cases for noSQL, RDBMS and warehousing.
In a way it’s interesting that we write and talk so much about what happens within our system because our high-level goal has always been to make NuoDB as simple to use as possible.
I got a chance to catch-up with Alek Mlynek, CTO of Clickspace, an online platform offering a wide array of multimedia services through websites.
