Delivering Business Value Faster Adam Anderson Delivering Business Value Faster Welcome to Delivering business value faster.

About Me Adam Anderson @SQLPioneer sqlpioneer.wordpress.com www.linkedin.com/in/adam-anderson-dba My name is Adam Anderson, and I have been a database developer for over 10 years and in IT for more than 20. I am MCSA certified and will be taking my final test in a month or two to get my MCSE. So I have a friend that is a financial accountant and he always droned on about ROI and how most people didn’t understand it. When I asked what he meant he told me that if you invest 100,000 dollars and a year later you get 12,000 dollars in return that was a 12% ROI and most companies would take that and run. However, if you can start making a 1000 dollars a month it is still the same money

Database Deployment Types

Deployment Types Migration Based State Based

State Based Deployments Create build artifact Compare artifact to destination Create script to modify destination Run Script on Destination

Advantages and Drawbacks State Based Handles code merges Better Acts more like OOP code Migration Based Handles working with data better Code merges can be more difficult Both Hard
