Question : (TCO 1) What are the duties of a data administrator (DA) with regards to a database, and how are a DBA’s (Database Administrator) tasks different from a DA’s in dealing with a database? Student Answer: The DA group is responsible for understanding the business lexicon and translating it into a logical data model. The DA would be involved more in the requirement gathering analysis, and design phases; the DBA in the design, development, testing, and operational phases. The DA is responsible for issues such as: *Identifying data owners and stewards *Setting standards for control and usage of data *Identifying and cataloging the data required by business users *Production of conceptual and logical data models to accurately depict the relationship among data elements for business processes *Production of an enterprise data model that incorporates all of the data used by all of the organization’s business processes *Setting data policies for the organization Instructor Explanation: DA separates the business aspects of data resource management from the technology used to manage data. There are more technical aspects of database design and daily operation requirements of a database. The DBA must understand the data models built by a DA.
