Relational Databases

Relational Databases Overview

A relational database stores and manages data by using a structured query language (SQL). The data is placed in a traditional table format containing rows and columns. Columns identify each piece of data by unique characteristics such as name, order number, or image of a product logo. Rows identify the relationships between the data points. Relational databases are used by businesses that want to store data and ensure access to customer information. Users are able to edit, return, or delete customer information as needed.

The main difference between relational and non-relational databases is the use of SQL. A relational database’s use of SQL assumes a defined structure or rows and columns. Non-relational databases use different storage models, are more scalable, and have a lower level of data integrity.

Relational Databases Features

Relational databases contain the following features and capabilities:

  • ACID (Atomicity, Consistency, Isolation, Durability) compliance ensures database transactions are processed reliably
  • Referential integrity ensures that relationships between tables remain consistent
  • Fine-grained locking or synchronization mechanisms for managing simultaneous access of the same data by multiple users
  • Support for Unicode for multilingual capability
  • Ability to run database seamlessly on multiple platforms
  • Ability to recover data in the event of a failure

Relational Databases Comparison

Before purchasing a relational database, consider the following:

  • Integration: Some relational databases do not integrate smoothly with non-SAP applications. Make sure the integration capabilities meet the needs of your business.
  • Extra costs: Relational databases may require extra hardware costs. When budgeting, you should account for devices and fees.

Pricing Information
