DBA

• Database Administrator (DBA): responsible for the planning, implementation, configuration, and administration of relational database management systems. Database administrators are normally proficient with one or more popular database software packages, such as Oracle or Microsoft SQL Server, and are normally familiar with one or more database query languages, such as SQL or MySQL. Database administrators sometimes hold certifications such as Certifed Oracle Database Administrator.

Database Analyst

• Database Analyst: responsible for designing and developing an organization's data flow models and database architecture. Although a database analyst may sometimes share administrative responsibilities with database administrators, analysts are normally responsible for designing the database schema which an organization will use to store and move business-critical data.
