Best Relational Databases Software

Relational databases store and manage data in a traditional table format, with each piece of data organized into a row and a column. Columns hold the data of a single type or field, like first name, order number, or the image link of a product logo. Rows create the relationship between these data points; for example, rows can associate a first name to a last name and then to a user name, email address, and customer ID. Businesses use relational databases databases to maintain the data from their applications and ensure they always have access to critical customer information, product data, social data, and financial particulars like purchases, fulfillment, revenue, and expenses. These systems can range from desktop applications that create a small database on your machine to large enterprise-grade data stores. Almost all utilize a form of SQL as their query language, and most adhere to the ACID set of properties to ensure reliable transactions (atomicity, consistency, isolation, and durability). Relational databases are generally chosen due to their simplicity in comparison to NoSQL database tools, such as object-orientated database tools, document database tools, and graph database tools. Those looking for a relational database solution with little budget also have options with free database software.

To qualify for inclusion in the Relational Database category, a product must

  • Provide data storage
  • Organize data in a relational model, formulating a table of rows and columns
  • Allow users to retrieve, edit, return, or remove data

    Amazon Relational Database Service (Amazon RDS) is a web service that makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity while managing time-consuming database administration tasks, freeing you up to focus on your applications and business. Amazon RDS gives you access to the capabilities of a familiar MySQL, Oracle or Microsoft SQL Server database engine. This means that the code, applications, and tools you already use today with your existing databases can be used with Amazon RDS. Amazon RDS automatically patches the database software and backs up your database, storing the backups for a user-defined retention period and enabling point-in-time recovery. You benefit from the flexibility of being able to scale the compute resources or storage capacity associated with your relational database instance via a single API call. In addition, Amazon RDS makes it easy to use replication to enhance availability and reliability for production databases. Amazon RDS for MySQL also enables you to scale out beyond the capacity of a single database deployment for read-heavy database workloads. As with all Amazon Web Services, there are no up-front investments required, and you pay only for the resources you use.
