When a databases security breaks down, an information breach can cause a global disaster.
Database engineer duties involve designing and building databases to make sorting through large amounts of data easier. One of the most important things to know about the databases they manage is — they hold a ton of information!
How Much Information Does a Database engineering
Have you ever really considered how much information a single database can hold? Consider the examples of the popular spreadsheet program Microsoft Excel that can process information requests on millions of rows of data.
While the idea of processing millions of rows of data at one time is impressive, what’s even more impressive is that databases can process information requests, queries, and tasks for billions of rows of data.
The database engineer is an integral part of information technology teams and systems worldwide.
Multi-faceted data professionals install and configure databases to meet client specifications and record search requirements.
They also require database engineers to make sure that the databases are secure and that they function properly for end users.
Database Testing and Monitoring – A Job Worth Millions
After implementing a new database, database engineers have to complete important testing and monitoring steps to determine if database troubleshooting is required.
Because the role of database engineers requires extensive troubleshooting, top-notch problem solving skills are mandatory in this role.
When updates need to be implemented, the database engineer needs to coordinate this with database end users and clients so that they can carry it out in the least disruptive way.
Interrupting the production of thousands of database users at once can cost companies millions of dollars in lost revenue.
Database engineer jobs require extensive experience with administering computer-based systems and providing support for databases.
Most importantly these highly trained professionals will need a lot of patience to sort out day-to-day data related problems.
Database Security and Usability
Security is not always the only issue that is important. Another thing that the database engineer may have to consider is usability for end users.
The database engineer must sometimes create a database that is easy for end users to enter data into. Sometimes, they require training and support for front-end users. Organizations provide this training to assure uniform practices in data entry and queries.
The database engineer may have multiple projects to manage, so it is important to work independently, to adhere to time constraints, and to work well under pressure, even when multitasking.
Teamwork skills are also essential in order to ensure the smooth implementation of databases with end users and clients who rely on the database to do their jobs. Advanced experience with Oracle and SQL is usually necessary, as these are widely used programming languages.
People who are considering a career as a database administrator need a minimum of a bachelor’s degree in computer science or a related field to get started.
Where Do Database Engineers Work?
You can find a database engineer working in the technical support department or information technology center in most large businesses. Sometimes, database engineers work offsite and provide data administration services from a remote location.
Because of the ongoing effects of the COVID-19 pandemic, many data engineers and data administrators now can work from home. They can work from virtually any location that provides uninterrupted internet access and privacy for management of confidential information.
The Difference Between Database Administrators Database Engineers
The career pathway of a database administrator and a database engineer are very similar. They require both to complete four-year degree programs in a computer science-based field. They also both require learning the popular and most widely used programming languages like SQL.
The major difference between the two is the fact that database engineers actually build the database. They create tables, queries, tasks, and input the data that makes the database function.
Database engineers are often confused with database administrators. This is a simple mistake, as they have similar job descriptions.
According to Indeed, the primary difference between the two is that “database engineers create databases while database administrators manage them.”
When you look at the definitions in these terms, it’s easy to understand the distinction.
