Data Base Administration .
A Data Base Administrator (DBA) is a specialized computer systems administrator who maintains a successful database environment by directing or performing all related activities to keep the data secure. The top responsibility of a DBA professional is to maintain data integrity.
This means the DBA will ensure that data is secure from unauthorized access but is available to users.
A database administrator will often have a working knowledge and experience with a wide range of database management products such as Oracle-based software, SAP and SQL, in addition to having obtained a degree in Computer Science and practical field experience and additional, related IT certifications.
Computer systems design and related services firms, banks, insurance companies, universities and health care are a few of the many different types of industries that a database administrator will find work.
In addition to being responsible for backing up systems in case of power outages or other disasters, a DBA is also frequently involved in tasks related to training employees in database management and use, designing, implementing, and maintaining the database system and establishing policies and procedures related to the organization's data management policy. The database administrator (DBA) is usually a dedicated role in the IT department for large organizations.
However, many smaller companies that cannot afford a full-time DBA usually outsource or contract the role to a specialized vendor, or merge the role with another in the ICT department so that both are performed by one person. The primary role of database administration is to ensure maximum up time for the database so that it is always available when needed. This will typically involve proactive periodic monitoring and troubleshooting. This in turn entails some technical skills on the part of the DBA. In addition to in-depth knowledge of the database in question, the DBA will also need knowledge and perhaps training in the platform (database engine and operating system) on which the database runs.
A DBA is typically also responsible for other secondary, but still critically important, tasks and roles.
Ensuring that only authorized users have access to the database and fortifying it against any external, unauthorized access.
Tweaking any of several parameters to optimize performance, such as server memory allocation, file fragmentation and disk usage.
Backup and Recovery
It is a DBA's role to ensure that the database has adequate backup and recovery procedures in place to recover from any accidental or deliberate loss of data.
Producing Reports from Queries
DBAs are frequently called upon to generate reports by writing queries, which are then run against the database.
It is clear from all the above that the database administration function requires technical training and years of experience.
Some companies that offer commercial database products, such as Oracle DB and Microsoft's SQL Server, also offer certifications for their specific products. These industry certifications, such as Oracle Certified Professional (OCP) and Microsoft Certified Database Administrator (MCDBA), go a long way toward assuring organizations that a DBA is indeed thoroughly trained on the product in question. Because most relational database products today use the SQL language, knowledge of SQL commands and syntax is also a valuable asset for today's DBAs.
