Best Relational Databases 2023: suggested for your needs

A relational database (RDB) is a way of structuring information into tables, rows and columns.

The best relational databases are a traditional means of storing and managing data, employing a structured table format. Each piece of information in these tables is neatly set up in rows and columns. Each column is for a certain type of data or field, like first names, order numbers, or even links to product logos. The real magic happens in the rows, which are where the connections between the different data points are made.

Relational databases are used by businesses to keep their application data organized and easy to find. These databases hold important information about customers, products, social data, and financial records, such as information about purchases, order fulfillment, income, and costs. These systems come in different sizes, from simple desktop applications that create small databases on your local machine to large, enterprise-grade data repositories. Below we have mentioned the best relational databases.

What are the Benefits of Using a Relational Database?

Relational databases are often used to store and manage structured data because they have a lot of benefits. Here are a few of the most important reasons why you should use a relational database:

🔍 Data Integrity: Relational databases use constraints like primary keys, foreign keys, and unique constraints to make sure that data is correct. This makes sure that the data stays correct and consistent, preventing errors and data anomalies.

📊 Data Structure: Relational databases use structured tables with predefined schemas to make it easier to organize and understand the data. This structured approach works well for applications that have complicated relationships between data.

🔍 Flexibility of Queries: Relational databases have powerful querying languages like SQL (Structured Query Language) that let users get, change, and analyze data in a flexible and quick way. SQL gives you a standard way to talk to a database.

🔒 ACID Properties: Relational databases follow the ACID (Atomicity, Consistency, Isolation, Durability) properties, which make sure that database transactions are reliable and keep data integrity even if the system fails.

🚀 Scalability: Relational databases can handle both small and large applications. Traditional relational databases may have problems with horizontal scaling, but modern relational database management systems (RDBMS) often have horizontal scaling solutions.

How to Choose the Right Relational Database for Your Needs?

Choosing the right relational database for your needs is important because it can have a big effect on the speed, scalability, and overall success of your application. Here’s a step-by-step guide to help you make an informed choice:

🔍 Figure Out What You Need: Start by understanding your application’s requirements. Consider factors such as data volume, complexity, read/write frequency, and data structure (structured, semi-structured, or unstructured).

🎯 Find Out What’s Important: Create a checklist of essential features from a relational database. This might include ACID compliance, replication, sharding, high availability, and compatibility with specific data types or query languages.

💡 Think about the performance: Evaluate the expected workload and tasks. Consider factors like read/write times, throughput, and the necessity for caching. Utilize benchmarks and testing to assess performance.

🚀 Needs for scalability: Determine if your application requires scalability through server expansion or resource upgrades. Some databases are more suited for horizontal scaling, while others favor vertical scaling.

🧩 Modeling data: Plan how your data will be structured and how relationships between different data elements will be represented. Ensure that your chosen data model aligns well with the chosen database system.


Which relational database is widely used?

Microsoft SQL Server, Oracle Database, MySQL, and IBM DB2 are all well-known examples of standard relational databases. Cloud-based relational databases, also called “database as a service,” are also widely used because they let companies outsource database maintenance, patching, and infrastructure support.

What is the fastest relational database?

Even though newer benchmark tests show that other RDBMSs like PostgreSQL can match or come close to MySQL’s speed, MySQL is still known as a very fast database solution.
