Database engineer vs. database administrator similarities and differences
Database engineers and database administrators work in the same general field, but the scope of their work is different. Here is an overview of the key differences between database engineers and database administrators that you should consider when planning your career options:
The primary difference between database administrators and database engineers is their daily duties and the overall scope of their work. Database engineers create databases, while database administrators manage them. To accomplish these goals, they focus on different tasks.
Database administrator duties include:
Installing database server equipment: Setting up the initial hardware for a database is an important part of being a database administrator. Database administrators can install, replace and repair the physical equipment involved in running a database.
Upgrading and updating software: Database administrators also sync database software with the hardware that powers it. They keep track of software versions and make updates or upgrades when necessary.
Determining database storage requirements: One of the responsibilities of a database administrator is to assess how much digital space the database needs to accommodate various projects and allocating storage space to different aspects of the database.
Creating user accounts: Database administrators help clients and other IT professionals access database information by setting up user accounts, adding passwords and closing or deleting old accounts to optimize database efficiency.
Managing user permissions and access: Databases often have some information or features that are only available to specific users. Database administrators assign permissions to each user and override access requirements for situations where a user needs additional permissions.
Implementing database security policies: To keep database and user information secure, database administrators create safety and security guidelines. They educate users about these policies and track user activity to identify security threats or unusual behavior in the database engine.
Backing up data recovery files: Database administrators create backup copies of the information in a database and the database code itself to make it easier to recover information and restore database functions in the event of data loss or function issues.
Archiving old information: To ensure that the database has available space for important information, database administrators review old information and archive data that is no longer critical to the database.
Restoring crashed databases: Database administrators ensure that a database can keep operating even when the system crashes. They help troubleshoot the cause of a database disruption and perform basic maintenance to restore the system and recover data.
Generating database reports: Database administrators also help pull data reports by entering conditions into the database software and combining different data sets.
Database engineer duties include:
Determining business requirements: Because data engineers are responsible for creating completely new databases, they first have to meet with clients to determine what kind of database infrastructure they need. They discuss the purpose of the database and set essential specifications for how the database should work.
Developing database architecture: Database engineers develop the digital architecture and database engine that allows the database to operate. They create spaces for data storage, add categories and establish rules for entering or editing new information entries.
Programming database algorithms: Programming, creating algorithms and using code is a standard part of building and updating a database. Database engineers create original database programs and adjust existing code to customize database features.
Setting data storage rules: Database engineers determine what happens to new information and where the database stores various data sets. They establish data pipelines and rules that make it easier for users to pull data sets and properly store new information.
Allocating computing resources: To build a new database or expand upon an existing one, database engineers determine what hardware and software resources they need to complete computing tasks. They also allocate these resources to different parts of the database based on storage and computing needs.
Analyzing data sets: Database engineers analyze patterns in data and look for trends to improve database operations and provide insights to their clients about how to best use their existing data.
Merging databases into a shared system: When a client needs to combine data sets from multiple sources, data engineers determine how to cohesively merge them into the same system by integrating categories and adjusting data entry styles to one consistent method.
Optimizing database efficiency: Database engineers make updates to databases to improve their efficiency and increase the speed of the database engine. They identify data sets or specific operations that have a negative impact on database function, then make adjustments as necessary.
Automating database tasks: To make it easier for users to interact with a database, database engineers identify common database commands and find ways to automate or simplify those tasks. They create macros that automatically initiate each part of the data pipeline or immediately generate a certain type of data set when users perform a specific action.
Both database engineers and database administrators should have at least a bachelor's degree in information science, computer science or a related field. Some roles that involve managing large databases require database administrators or engineers to have a master's degree in IT. Database engineers may also choose to major in a subject like engineering or mathematics with an emphasis on software and computer-related topics.
People interested in becoming database administrators should select college courses that help them develop the knowledge and skills to manage a complex information system. Examples of subjects to study during college for aspiring database administrators are:
