PDXPUG - March meeting next week

When: 7-9pm Thu Mar 20, 2014
Where: Iovation
Who: Mark Wong
What: An Adventure in Data Modeling: The Entity-Attribute-Value Model

Emma, Inc. is an email marketing company that provides a Web based
application for managing email lists and marketing campaigns. This is a
tale about Emma's experience with a database schema design refactor that
is now using the Entity-Attribute-Value (EAV) data model on the members
in email lists. We will briefly describe the previous data model and
why we had to move to a new one. This is followed by all the places
where Emma stumbled and recovered in implementing the EAV data model and
rebuilding the application around it. Finally we will touch on where
Emma might go next with respect to the data.

Mark is a Data Architect at Emma, Inc. and works with their PostgreSQL
database systems.
