The Data Warehouse Developer is a member of the Business Intelligence (BI) and Database Administration Team within the Office of Information and Technology Services (OITS). The Data Warehouse Developer reports to the Director of Business Intelligence and Database Administration, works in collaboration with other Business Intelligence and IT staff, and is a member of the team responsible for implementing and delivering business intelligence and data integration solutions to Excelsior College.

The Data Warehouse Developer is a key participant in on-going efforts to build data integration solutions supporting both business intelligence and transactional systems based on a data integration hub architecture. The hub architecture provides operational data stores used by various systems to consume and publish transactional data. It incorporates extraction, transformation, and loading processes to bring data into the hub and to accommodate data exchange between systems and with a data warehouse used for business intelligence.

The Data Warehouse Developer is expected to develop an in-depth understanding of data maintained in various transactional application systems used by Excelsior College (both internally-hosted and cloud-based) and how data from these systems are best organized and integrated to support transactional, reporting, and analytic needs. This position has responsibility for technical design, development, implementation, maintenance, and documentation of data integration processes.

Data Cookbook is employed as a tool for communicating data definitions and promoting data quality and consistency for BI deliverables. BI data sources consist of a custom student information system; a learning management system; CRM systems for prospects, students and alumni; a financial aid management system; and various web and social media activity tracking systems.
