What are Relational Databases?

TLDR;

  • Databases store information in an organized way
  • Relational databases use multiple tables with relationships to each other, allowing for easier database modifications
  • Non-relational databases store information all in one place, allowing for faster speeds
  • Xano provides the advantages of relational and non-relational databases out of the box

Introduction to Databases

Databases store information in an organized way, like a filing cabinet for your bills. The tables in a database act like the folders in your filing cabinet. There are two main types of databases: relational and non-relational.

Relational Databases

Relational databases contain tables that relate to each other. If you needed to get your medical bill from the cabinet, you would go to the medical folder and pull out the record corresponding to your name.

Similarly, relational databases use tables (like folders) and keys (like a person’s name) to store and retrieve information. These keys can correspond to many tables, making it easy to grab relevant information.

Non-relational Databases

Non-relational databases store all the information in one place, like having all your bills in one folder. This might make it faster to retrieve information than having to go to multiple folders, but it does come at a cost in terms of flexibility.

If you wanted to change the address on your medical bills, you’d have to search through the whole document to change each one. With relational databases, though, you could make the change within just the medical folder.

Which to Use

So are relational or non-relational databases more effective overall? It’s hard to say. If you have a firm understanding of the data you need then a non-relational database might be better. Otherwise, it could be better to work with a relational database so modifications can be made with ease.

Why Use Xano for Your Database
