Data Architect is a natural evolution from Data Analyst and Database Designer, and reflects the emergence of Internet Web Sites which need to integrate data from different unrelated Data Sources. These Sources can be either :- External and Internal. External : such as Market Feeds, and News Agencies. And, Internal : such as existing systems, such as HR for Employee details. Data Architect will work closely with the Users, systems designers and the developers on a Project team. It is closely allied with business architecture and is considered to be one of the four domains of enterprise architecture.
