Live from #OTW14: Worst Data Warehouse Design Practices

Back in September at the now annual OakTable world (OTW) at Oracle OpenWorld, I was privileged to give a talk where I ranted a bit about some of the worst data warehouse design mistakes that I have seen.

Well, if you missed out, now you can see that talk thanks to Kyle Hailey who had all the OTW talks videoed. This week, he tweeted that the video was ready for viewing.

So if you missed the talk, or just want to see it again, check it out!

Select the relational model from the Browser. Right-click and select “Discover Foreign Keys”. I have two tables: CUSTOMER and ORDER.

Say “Big Data” One More Time (I dare you!)

This is quick. Saw it on Twitter this morning and it is just too funny to not share:

Have a great day!

My Data Model Checklist book is now available in Spanish – Just in time for #OOW14!

Exciting news!

I just got this email from Amazon:

Congratulations, your book “UNA LISTA DE VERIFICACIÓN PARA REALIZAR REVISIONES A LOS DISEÑOS DE MODELOS DE DATOS” is live in the Kindle Store and is currently enrolled in KDP Select. It is available for readers to purchase here.

If you are in Mexico, you can get the book here.

If you are in Spain, you can get it here.

Now, truth is I do NOT speak, read or write Spanish. But my good friend, and Oracle expert, Galo Balda does!

I am very grateful to Galo for putting in the effort to translate my little book so other data professionals around the world could read it in their native language.

You can (and should) follow Galo on Twitter, and on his personal blog in either English or Spanish.

BTW – Galo is speaking at OOW14 too, so if you are going, please drop into one of his excellent sessions on Pattern Matching (Session UGF4482) and Regular Expressions (Session CON4493).

Muchas Gracias Galo!

See you all at OOW!
