“There are four things that motivate open source development teams:
1. The challenge/puzzle of programming, 2. Need for the software, 3. Personal advancement, 4. Belief in open source” — Bruce Momjian.

On PostgreSQL and the challenges of motivating and managing open source teams, I have interviewed Bruce Momjian, Senior Database Architect at EnterpriseDB, and Co-founder of the PostgreSQL Global Development Group and Core Contributor.

Q1. How did you manage to transform PostgreSQL from an abandoned academic project into a commercially viable, now enterprise relational database?

Bruce Momjian: Ever since I was a developer of database …

A number of folks have asked me to create a post of a PostgreSQL installation on Windows. So, here is my step-by-step PostgreSQL 9.3 installation.

Download PostgreSQL Database

You can start the download of PostgreSQL from this site. It leads you to the EnterpriseDB site, where you can download the prepackaged software.

Install PostgreSQL 9.3 on Windows

These steps walk you through installing PostgreSQL and the the pgJDBC v9.3, psqlODBC (32 bit), and psqlODBC (64 bit) packages.

1. The first thing you need to do is launch the …

“Application designers need to start by thinking about what level of data integrity they need, rather than what they want, and then design their technology stack around that reality. Everyone would like a database that guarantees perfect availability, perfect consistency, instantaneous response times, and infinite throughput, but it´s not possible to create a product with [...]

I guess I brought the snow with me to New York as I awoke to a nice 10cm dump. Anyway today would best be described as a day of ‘Disruptive Tech’

I first attended Kevin Kempters intro into PorstgreSQL High Availability. A very well balanced presentation that gave a very good overview of what is available out of the box for both Warm Standbys and Hot Standbys how they can be very easily implemented. He also gave a quick overview of other tools that can be used including Slony for detailed fail-overs and PgPool for load balancing and relication. Not very disruptive but it does show that Pg is on par with most of the heavy hitters such as MySQL and Oracle.

The keynote this year was by Ed Boyajian the CEO or EnerpriseDB and he gave an big picture of the DB in terms of market which is a whopping 26$ Billion a year in the US alone of which the the two five players have 90% of the market one having more than half.

He made …

When we published our 2008 report on the impact of open source on the database market the overall conclusion was that adoption had been widespread but shallow.

Since then we’ve seen increased adoption of open source software, as well as the acquisition of MySQL by Oracle. Perhaps the most significant shift in the market since early 2008 has been the explosion in the number of open source database and data management projects, including the various NoSQL data stores, and of course Hadoop and its associated projects.

This is an updated version of a post that was originally published in July 2009. It has been updated in response to ongoing confusion about open core licensing.

There has been a significant amount of interest in the open core licensing strategy since Andrew Lampitt articulated it and its benefits for combining open source and closed source licensing.

There remains considerable confusion about exactly what the open core licensing strategy is, however, which is strange since the term arrived fully packaged with a specific definition, courtesy of Andrew. Recently I have begun to wonder whether many of the people that use the term open core regularly have even read Andrew’s …
