There are several variations of database management systems available for consideration. Each system will have benefits as well as drawbacks, and the system that is selected will be determined purely by the requirements of the company and the activities that will be carried out using the system. Database management systems include things like MySQL, Microsoft SQL Server, Oracle, dBASE, and FoxPro, just to name a few examples. There will be significant differences in the degree of safety implemented by each of these database management systems. For this reason, it is of the highest essential that a firm exercise extreme caution when selecting the appropriate database management system to meet the unique requirements for data security posed by that organization. For example, a business like a bank that handles a large volume of personal information from a large number of people will require considerably more stringent security standards than a firm in a small town would. The primary focus of this research paper will be a description of the various types of database management systems that are currently available, as well as what each of these systems offers. The paper will also include subtopics that focus on the type of security that each system offers, as well as what kind of business each database management system would be most suited for. The aforementioned database management systems will each receive an in-depth analysis, during which both their positive and negative aspects will be discussed. Additionally, each system will be matched to a real-world example of the kind of organization that it would serve most effectively based on the features and level of security that it provides. This will be done in order to ensure that the systems are as comparable as possible. Any organization that is in the process of selecting a database management system has to give careful consideration to the system’s level of security and the means by which the firm will secure its customers’ personal information from unauthorized access from the outside.
