Who consults with system analysts and programmers on project that require access to or the creation of databases? Select one: a. Network engineer b. Computer operator c. Computer engineer d. Trainer e. Database administrator
The correct answer and explanation is:
Correct Answer: e. Database administrator
A Database Administrator (DBA) is the professional who regularly consults with system analysts and programmers on projects that require access to or the creation of databases. This collaboration ensures that the database structures are designed efficiently, data is accessible as needed, and security and performance standards are met throughout the development and operational phases.
The main role of a database administrator is to manage and maintain databases. They are responsible for ensuring that data is stored securely, backed up regularly, and retrieved quickly when needed. They play a vital role in defining the database architecture and ensuring it aligns with the software applications being developed by the programmers. When system analysts design systems to meet business needs, DBAs help them understand how data will be handled, including storage, relationships, integrity constraints, and access permissions.
DBAs also advise programmers on how to efficiently query the database using Structured Query Language (SQL) and how to optimize database performance. During the development phase, they assist with testing, tuning, and implementing changes that might affect the database.
In contrast, the other roles listed serve different functions. A network engineer manages network infrastructure. A computer operator typically oversees routine operations and maintenance tasks. A computer engineer designs and develops hardware systems and some embedded software. A trainer educates users on software or systems but does not engage in technical development or database management.
Therefore, whenever a project involves complex data requirements, such as designing a new database or integrating existing databases into new systems, the database administrator is the key consultant to ensure data is managed properly and that the database system supports the application’s goals efficiently and securely.
