What this article shares with you is about the differences between non-relational and relational databases. The editor thinks it is very practical, so I hope you can learn something after reading this article. Let's take a look at it with the editor.

The latter is in table format, so it is stored in the rows and columns of the data table, while the former is not suitable for storage in the rows and columns of the data table, but is grouped together in large chunks.

2. The former supports fine-grained control over the atomicity of transactions, and it is easy to roll back transactions, while the latter can use transaction operations, but it is not as stable as the former.

Advantages and disadvantages of non-relational and relational databases

Advantages of non-relational databases:

1. Performance

NOSQL is based on key-value pairs, which can be thought of as the correspondence between primary keys and values in the table, and does not need to be parsed by the SQL layer, so the performance is very high.

2. Scalability

It is also because there is no coupling between the data based on key-value pairs, so it is very easy to scale horizontally.

Advantages of relational databases:

1. Complex query

You can easily use SQL statements to do very complex data queries between one table and multiple tables.

2. Transaction support

So that the data access requirements with high security performance can be realized.

These are the differences between non-relational and relational databases. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
