MySQL, Oracle and SQL Server Database Management System Comparison.
There are different features that usually make database management systems more
preferable by different users. MySQL, oracle and SQL server are the most utilized database
system. Although, these database systems usually have different similarities they as well have
different differences (McClure, W. B., Beamer, G. A., & Croft, I. V. J. J. 2005). For an
organization or individual to select the most appropriate database system, it is greatly important
to compare the verity of options available and select the most suitable for their operations. The
comparison is usually based on different feature for the database management servers. Some of
the features that plays a big role in selection of the appropriate dataset management system are
disk space, memory, database authentication, and schema objects.
Data space is the space for installation of the system in a computer to ensure that it
operates appropriately on the RAM devices, while, memory is the internal storage in the
computer device that is random access memory and read-only memory. Database authentication
is the process of ensuring that the users who access the database system are authorized and they
can only view the information according to the access right offered to them (Jones, A., Stephens,
R. K., & Plew, R. R. 2005). Schemas objects are the data structure that are logical, having no
one-to-one physical file correspondent with on the disk that usually stores the information. Data
type is a feature of database system that are the attributes specifying the type of data in the
database management system.

Conclusion
It is exceedingly important to select the most appropriate database management system
that suits the organization operations. Although there are different similarities between these
systems, there are different features as well that makes them unique and suitable for different
operation (McClure, W. B., Beamer, G. A., & Croft, I. V. J. J. 2005) Security of the system is the
first consideration that should be necessarily considered while selecting the database
management system.
