Benefits of Relational Databases
I am sure you have come across this word, but what exactly does it mean? Well, this is a popular method used to store large sets of data in a systematic manner. Data is organized in such a way the users can easily understand the information. In a relational database, data is compared or grouped by type, for instance name or year.
1. Supports set functions
Relational databases have an array of roles that create user-friendly manipulation techniques. These databases are commonly used in set operations as well as relational algebra. They include simple operations, like join and divide. Moreover, they facilitate data manipulation through the Structured Query language, commonly known as SQL.
Another benefit of using a relational database is efficiency. Since it allows better data manipulation, it becomes easy to save a large set of data in one location. In other words, this helps to save time since there is no need of data duplication. Because all the data is stored in one location, users can make modifications where it deems fit.
Since data is stored in a systematic manner a relational database shows a clear connection between different sets of data. The connection of different sets of data makes it easier to understand the relationship two sets of data.
4. Boasts excellent security
Relational databases are popular as they have reliable security. They support access permission to ensure that data is only accessible by those who have permission. In simple terms, they support end user rights and create privilege, select and insert rights, which allow users to make corresponding operations or modifications on the database.
Another reason as to why relational databases are popular is that they are customizable. Therefore, users have the freedom to delete or customize a view without interfering with the data.
Setting up a relational database is expensive since you need to buy special software.
