Have you ever imagined what people do and whom they approach when they come across their health problems? Yeah, your guess was right; it'll be your family doctor. However, when there exists a problem in the network of your company, software or hardware of the system, can these doctors heal it? No way. But, how about a doctor in disguise? Right 'm talking about the System Administrator. System Administrator or Sysadmin is a person responsible to maintain and operate a computer system and/or computer network.
So lets us now see what exactly Systems Admins are supposed to do? There's no such, hard and fast rule describing the roles and duties of a system administrator. The duties of a Sysadmin vary widely from one organisation to another. Some are usually given the responsibility of installing supporting and maintaining the computer systems and the main server. Some may be given the task of maintaining the networking tasks within the area or campus specified.
Skills required by a System Administrator:
• A thorough knowledge on the latest Operating Systems and Applications
• Hardware and Software troubleshooting skills.
• Knowledge about the networks.
• And the most important skill being "Problem-Solving". This would mean understand the purpose for which people in the organization use the computers.
• Keep an eye over the network security by deploying software patches soon after its release.
• Keep performing regular back-ups of the firm's data.
• Adding, deleting, modifying or resetting the user account information.
If you're on the path to a career in database administration, make sure to both develop a core competency in computer science and database technology, as well as gaining work experience during your training. By developing a broad understanding of development software, you will put yourself in a position that you can master a number of programs and can transition from one to another if necessary. Determine which database vendor which your prospective employer utilizes and begin improving your skills with the system.
For those working with Oracle, you should work with materials in the Oracle Certified Professional program which allows you to earn an initial certification as an Oracle Certified Associate.

Microsoft has a broader array of certifications, ranging from the Certified Application Specialist program, which gives you expertise in Access and Office, as well as the more analytical Certified Technical Specialist. As a Technical Specialist, you can begin working with the Microsoft SQL servers which many professional organizations run, and can work toward further Technical certifications in Business Intelligence and Database Development. Those seeking the highest salaries in Microsoft companies should train for a Certified Information Technology Professional credential, which is the most respected Microsoft certification.
