Many employers are seeking young and talented individuals who understand the Oracle Database and how it ties into the current marketplace demands.


Oracle has more than 300,000 Oracle Database customers who have deployments across a wide variety of industries, and who use databases for many different reasons. Oracle Database enables IT professionals to deliver more information, with a higher quality of service; to make more efficient use of their budgets; and to reduce the risk of change in datacenters. As companies continue to expand globally, they need to ensure that their datacenters are always up and running.


Is your employment future uncertain after college? Becoming familiar with Oracle Database technology could put you in line for a promising career that targets industries experiencing real-world business challenges. Many companies that use the Oracle Database are eager to employ more technologists who not only know how to perform the role of a DBA, but who are passionate about learning how to solve today’s critical business issues as well.


There are a number of interesting jobs available to a DBA, but three of the most highly sought after roles are those of Database Administer, Database Security Engineer, and Database Scientist. Below are descriptions which outline some of the skills that individuals seeking these roles should develop:


Database Administrator


Responsibilities of a DBA typically include database Installation, configuration, upgrade, and migration. This requires knowledge of the hardware prerequisites for an efficient database server, as well as being able to communicate those requirements. The DBA installs database software and selects from various options in the product to configure it for the purpose it is being deployed.


A DBA must also deploy new releases and patches as they are developed, as well as be able to transfer data from legacy systems to new ones. DBAs are required to perform backup and recovery for the databases they manage. They must understand the particular security model that the database product uses and how to use it effectively to control access to the data.


Additionally, a DBA is responsible for monitoring the database server and tuning it for optimal performance. When problems arise, a DBA must troubleshoot the database server and correct any issues to avoid losing any data.


Database Security Administrators and Engineers


Evolving technology has resulted in several new database security roles. Because databases centralize the storage of data, they are desirable targets for hackers. The DBA must understand the particular security model that the database product uses, as well as how to use it effectively to control access to the data.


The three basic security tasks are authentication, authorization and auditing. Database security engineers are needed who can analyze the threat potential at every level of the database structure and suggest necessary security patches. This must be done early in the development cycle, as hackers will target any security weaknesses, potentially gaining access to the system’s features and data.


Other database security engineer tasks require them to interact with DBA team members to make sure security standards are implemented across all company databases, stay current on best practices that are relevant to organizational requirements and recommend and implement security standards.


Database Scientist — Big Data


Entering the Big Data realm requires an aspiring data scientist to attain multidisciplinary skills, including Hadoop, MapReduce, database, data warehouse, and streaming. Data Scientists are responsible for designing, developing and implementing data analysis, and applying data science techniques for data exploration.


A key responsibility may include conducting data analysis, research and data modeling using structured and unstructured data. Data scientists will need to be able to verify the integrity of the data used for analysis within an organization and utilizing the correct database functionality can provide them with the right framework to do this. They will need to communicate complex results in a clear manner to help organizational leaders determine the best way to utilize the data to support company goals and business growth.
