Building custom analytics applications requires Data Engineers to not only know the data well, but also to understand the analytic needs of the different groups across the company. They must work closely with these analysts to plan and build these custom applications. So, in addition to having the programming skills, it is important to have good communication and teamwork skills.

"The Marketing department was looking to marry its primary Marketing Research data with sales data stored in our corporate databases. The custom application I built, allowed them to conduct ad hoc analyses quickly, which in turn helped them react quickly to the competitive environment. The application allowed them to avoid the traditionally long process of requesting data from the data warehouse and loading it into Excel or Access."
