At Percona, we monitor our users’ needs and try to accommodate them. One aspect we monitor is the MySQL version distribution/utilization. Observing that, we identified a very interesting trend: the lack of migration from 5.7 to 8.x, or better yet, the need of many to remain on 5.7.  That observation has triggered several actions from […]

Do you ever stop and think? It happens to me all the time, random subjects kick in and I end up searching (aka googling) and today I wondered … Why is MySQLs logo a dolphin? Shame on me it took me so long to ask the question but as the saying goes, better late than never.

It combines great symbol value with a powerful, modern design.”

After a while the name was chosen out of 6357 suggestions by the community and that is how Sakila the dolphin came to be :) …. and we lived happily ever after (or at least hope to!)

It has been a while since I posted on my blog - in fact, I believe this is the first time ever that more than one month passed between posts since I started blogging. There are a couple of reasons for the lag:

• 
  
• Matt Casters, Jos van Dongen and me have spent a lot of time finalizing our forthcoming book, Pentaho Kettle Solutions (Wiley, ISBN: 978-0-470-63517-9). The book is currently being produced, and should be available according to schedule in early September 2010. If you're interested, you might like to read …

Taking TOTD #121 forward, this blog explains how to create a JPA Persistence Unit for a MySQL sample database and package it as a library. This JAR file can then be easily included in other web applications.

Lets get started!

1. Configure GlassFish for using the MySQL sample database (sakila) as described in TOTD #121.
2. Add the GlassFish instance in NetBeans IDE using "Services" panel.
3. Create JPA entities using NetBeans IDE.
   1. Create a Java class library:

This blog clearly explains how to configure the MySQL sample database (sakila) with GlassFish. Even though the instructions use a specific database but should work for other databases (such as Oracle, JavaDB, PostgreSQL, and others) as well. The second half of the blog provide specific syntax for the Oracle sample database.

1. Download sakila sample database and unzip the archive.
2. Install the database as described here - basically load and run "sakila-schema.sql" and "sakila-data.sql" extracted from the archive.
3. Create a new MySQL user account using MySQL CLI Admin and assign the privileges
   …

This Thursday (July 2nd, 13:00 UTC), Roland Bouman will will take the Sakila sample database and explain how to design and load a data warehouse for it, and how to use that to create those reports and charts that make managers smile. Along the way, he'll explain often uttered terms and concepts such as dimensional model, denormalization, star schema, OLAP, data staging, business intelligence, ETL and data integration. Roland's session is titled Starring Sakila - A Data Warehouse Mini-Tutorial.
