Any company or service requires the storage and regulation of a large amount of data that needs to be handled on a daily basis and updated in particular ways in a systematic manner. This is what Database Administrators or DBAs are trained to do. By using specialized software for this purpose, they organize data for quick retrieval and understanding. The various requirements and functions to be a database administrator are given below.
Tasks carried out by DBA experts
The function of a database administrator is a technical one which involves the integration of various functions related to database security management, formation of the data analysis system, monitoring the performance levels, as well as ensuring that the required standards posed by the organization are in place.
- Database Selection
The first and foremost requirement is to ensure that the database that is selected is of the right quality and has suitable hardware and software. This involves being up-to-date with the trends in the market, having technological knowledge regarding the different operations that are offered by each system, being aware of the established and tested models, as well as being able to predict to a certain amount, the reach that the database would have in the future as well as changes that would be made to the kind of operations that are available.
- Security Measures
Remote DBA experts would also know how to ensure that the database is safe from various threats and has no danger of privacy infringement. This means that the DBA has to make sure that the required individuals have access to the data, and not any others. Security could be infringed due to errors in the system itself, due to viruses or malware, hackers and other outside forces, or inconsistency in which the data is managed and stored.
III. Creating Backups
Another requirement when it comes to setting databases up is to ensure that there are necessary backup protocols in place. The DBA expert would have previously determined guidelines on the frequency of data backup, the extent to which the data needs to be backed up, as well as various measures for recovery of the information in case the data is obtained by outside forces. This would also involve prioritizing certain parts of the entire database and arranging them in a way that gives clarity about which parts need to be backed up, where they need to be backed up, and how periodic it needs to be. Backing up is usually done on a weekly or monthly basis, depending on the above factors.
- Database recovery
Furthermore, it needs to be assumed that there may be times in which the entire database fails and needs to be recovered. This is in association with the previous point of backups, but in a greater magnitude. Recovery also includes keeping a log of the kind of entries that are made in the database, the exact date and time at which they were made, as well as the people who were given access to it. This would enable the DBA expert to be able to access the required information at a moment’s notice if required. There’s also the establishment of different save points which would help in ensuring that only certain parts of the data may be lost and need to be recovered rather than the entire amount that had been stored.
- Knowledge of Operating Systems and Programming Languages
The remote DBA expert would also need to have certified skill sets and knowledge regarding the different kinds of operating systems or programs that are involved in the creation of the entire database system. This is to ensure that any kind of bugs in the coding can be rectified without too much hassle, and the software can be fine-tuned or upgraded when necessary. Experts also are able to customize certain options or functions by making modifications to the base program in order to ensure that it meets the company requirements.
