Database Administrator: These professionals are in charge of designing data models in a database system, implementing these designs, and testing them to ensure they perform their intended functions. In general, this role entails working with all three levels of technology involved in databases, namely logical, physical, and programming.

Database Developer: Database developers create data structures and associated access routines for use by applications. They may be responsible for creating databases, designing table layouts, creating indexes, and writing queries, among other things. Some of their tasks are similar to those performed by database administrators, while others may be significantly different, depending on job role or project requirements.

Data Analyst / Data Scientist: These professionals analyze and interpret data to discover business trends and patterns. They extract meaningful patterns, trends, and conclusions from raw data such as sales figures or product usage statistics to provide valuable insights for planning purposes.

Data Architect: Database architects are responsible for designing the overall structure of a database system, including determining data modeling concepts such as entity-relationship diagrams. They create logical structures such as tables and columns, which allow developers to create physical structures with advanced tools like Erwin.

Data Engineer: These professionals are in charge of designing data-intensive systems that are typically highly scalable. They do not typically deal with individual bits and bytes or database cells; rather, they ensure that large amounts of structured/unstructured data can be efficiently stored, retrieved, and processed promptly.

Business Analyst: Business analysts are typically tasked with understanding how an organization’s current business functions work to identify ways in which existing or future systems can be used to improve these processes. They may also be responsible for determining how information flows through different parts of the organization to make sure that everyone has access to the details they need to make better decisions, including what data is required at each stage of the process.
