The role of a database administrator varies depending on the size and growth level of a company. Their main responsibility is to develop an efficient and secure structure for managing company information, including ensuring server uptime, developing backup systems, and protecting against unauthorized access and system failure.
The role of a database administrator in a company parallels the company’s growth level and the company’s ultimate goal in terms of database requirements. This is because companies are generally at different stages of growth and their requirements for database management are generally sympathetic to that level of growth. For companies with many subsidiaries and a lot of information flow, the Information Technology (IT) department will be clearly defined, with a large number of employees with specific functions. On the other hand, smaller companies may not have a clearly defined IT department, and the database administrator may find himself performing a variety of roles that are not particularly restricted to just managing the company’s database. The main responsibility of the database administrator is the development of an efficient and secure structure for the management of the information, generated and related to the company.
A database administrator role is ensuring that the company’s servers are always up and running. If there is a problem with the servers, the database administrator’s role is to ensure that there is a competent backup system in place that will keep the organization functional until the problem with the server is resolved. Another addition to the database administrator role is the development of a secure system for protecting company information from unauthorized access. To this end, the database administrator must keep himself constantly informed about the latest developments in the IT world, to better protect the company’s server from contamination by viruses and other forms of spyware and malicious malware.
An addition to the database administrator role is the recovery of information in the rare case of system failure. This care should be built into the development of a backup plan and should include specific steps for safe and effective recovery of vital information. In large corporations, the database administrator may need to develop a type of tiered system where there are varying levels of access to the database. This may include assigning codes and passwords to different categories of employees so that they can only gain access to the portion of the database that they have been cleared to access.
