What Are the Advantages of Relational Databases

The many advantages of relational databases can easily be summed into one major advantage: relational databases are dynamic. If you compare a relational database to a flat file database, which is a static data table, you will instantly see the advantage to the former. The ability to bring connections within a database to the surface makes the data within even more valuable.

Relational databases bring tables together.
In the example of a flat file database, tables are solitary. In other words, they do not know that other tables exist. In a relational database, not only are the tables aware of each other, but they also communicate and share information. This means a user can search for related material across multiple tables. In a flat file database, a user must manually search through each table for related information, which takes time.

Structured query language is easy to understand.
Relational databases use a structured query language, also known as SQL. SQL gives instructions in a simple format. In other words, when you are using a relational database, you will not feel like you are eavesdropping on a conversation between robots. These databases also provide lightning-fast results as opposed to traditional means of retrieving data.

If security is a top priority with your information, you can build an interface on top of a relational database that provides various levels of privacy options. For example, lower-level employees can be restricted from seeing the data available to management. In another example, some databases can be locked away from others to ensure that not all information is recalled when accessing a record. This is good news for companies handling sensitive information, such as credit card numbers and personal notes.

One of the major benefits of relational databases is its ability to expand as the company's data grows. A flat file has its limits, but a relational database can reveal connections among data that wouldn't be visible otherwise, no matter how much data is entered into the database. Simply generate a report, and you can track the status of your products or your customers.
