Open Source Database Alternative – Ingres

On several occasions this year I’ve been prompted to mention in conversation Ingres as an alternative Open Source Database. Jonathan Levin in A list of Open-Source Alternatives to Business Applications was the latest example where Ingres was not mentioned and perhaps it should have been.

Want features like online backup, online alter, multi-master replication, parallel queries and partitioning. These are all long existing features in a more mature product then MySQL presently. Is this a sleeping giant that nobody remembers about? Ingres has been around a long time, in fact my experience extends back to 1988 (that’s 20 years).

From a product perspective they have created a number of pre-packaged product stacks, for example The Ingres Icebreaker BI Appliance Powered by JasperSoft , something MySQL has failed to capitalize on. Another stack appliance for example is with Alfresco.

However since the CA announcement to open source Ingres back in 2004 I’ve not seen a great deal of press, at least not in the Open Source or MySQL circles. Time permitting myself it’s time again to look at Ingres. It’s worth another look and hopefully I can provide some translation for MySQL DBA’s and Developers. Also part of Ingres is ABF Application By Forms, an entire development environment. My use was back in the terminal days so I can only assume they have fully embraced the Web now.

Extending MySQL Capabilies with UDFs, Plugins and Components - Part 2

MySQL offers three different approaches to extending the SQL capabilities with the default product you download and install. These are: User Defined Function (UDF) MySQL Manual MySQL Plugin MySQL Manual MySQL Component MySQL Manual In my prior post I provided a new uuidv function that accepted a numeric argument to return a string of the version of UUID specified.
