It is an opportunity to meet new people, make new friendships and find out what is going on in the data industry in Melbourne.

This Month’s Speaker and Topic
Igor Rozenberg – Entity Attribute Value (EAV) SQL anti-patterns
Igor is a Senior Consultant at UXC. He graduated in Robotics and Computing in Moscow USSR before arriving in Australia in 1992. His first experience with relational databases was with Microsoft Access and has worked with Microsoft SQL Server (since version 6.5 to Azure SQLDB). He does toy with other RDBMS such as DB/2, Oracle and Sybase. His hobbies include Space exploration, and he is a member of the Space Association of Australia.
This session is dedicated to revealing “The god, the bad and the ugly” sides of EAV (Entity Attribute Values) modelling that is based on the mathematical notion of a sparse matrix.
First we’ll show what could be wrong with a brute force approach to implementing EAV and compare side-by-side traditional row-based entity implementation with EAV implementation.
Then we will show a pragmatic implementation of and EAV model build on top of a RDBMS (like SQL Server) based on experience with two-way synchronization challenges between a centralized server database and local databases on occasionally connected tablet devices.
Once again we are fortunate to have wonderful sponsors on board who will ensure that we are suitably fed and watered. A big thank you to Lobsterpot Solutions and Pluralsight for their ongoing support of this great community event!
