What Is a Relational Database?

In the realm of Information Technology (IT), data is considered as valuable as gold. The significance of data management cannot be understated, and this is where relational databases come into play. As a crucial part of an IT infrastructure, relational databases play an indispensable role in organizing, storing, and retrieving data efficiently.

What is a relational database?

A relational database is a type of database that uses a structure allowing for the identification and access of data in relation to other pieces of data within the database. Often, data in a relational database is organized into tables, which is different than non-relational databases. These tables are used to hold information that is related in some sense.

Structure of a relational database

When setting up a relational database, tables are created and data is categorized into these tables. Each table, which can be thought of as a ‘relation’, contains one or more data categories in columns. Each row, also known as a record or tuple, contains a unique instance of data for the categories defined by the columns. The power of a relational database lies in its ability to efficiently retrieve data from multiple tables in a coherent and integrated form.

Benefits of a relational database

  • Data consistency: In a relational database, data is not duplicated. This ensures that the data remains consistent across the database. With no data redundancy, it becomes easier to manage, update, and ensure the accuracy of the data.
  • Flexibility: Relational databases are flexible because they allow the user to manipulate the data stored in them using queries. These queries can combine data in many ways and support a wide range of complex applications and business logic.
  • Security: The data stored in relational databases can be controlled at a granular level. Access to the data can be managed according to the different levels of user rights, ensuring the security of sensitive information.

3 questions to ask when choosing a relational database

  1. What is the scalability of the database? Consider the ability of the relational database to handle an increasing amount of work in a capable manner when its resources are extended. The database should be able to grow with your needs.
  2. How secure is the database? The database should have robust IT security measures in place to protect sensitive data. This includes access controls, encryption, and regular security updates.
  3. What kind of support is available? Look into the kind of support provided by the database vendor. They should offer comprehensive IT documentation, responsive customer service, and a strong user community.

Wrapping up relational databases

Understanding relational databases and their benefits is vital for anyone working in IT. These databases offer a powerful and flexible way of managing data, ensuring consistency, flexibility, and security. When choosing a relational database, considerations around scalability, security, and support are crucial. With a well-chosen relational database, organizations can support IT efficiency and ensure secure data management.
