![]() non-relational databases have been designed from the groundup for the cloud, which makes them naturally good for horizontal scaling where lots of smaller servers can be spun up to handle increased load. If you want a flexible schema for the data i.e in terms of shape or size, or if it needs to be open to change in the future, then a non-relational database is the answer. In a non-relational database documents are embedded within documents, which helps keep data that will be accessed together in the same place, but if this isn’t right for your needs, use a relational database, for example, if you have a large dataset with complex structure and relationships, embedding might not create clear enough relationships.įinally, relational databases have been around for a very very very long time which means there is wide support available, from tools to integration with data from other systems. Normalization in a relational database reduces the size of the data on disk by limiting duplicate data and anomalies. Also, if relationships between entities are important, again relational databases are the best choice. Well, relational databases are still the best choice if the data is predictable, in terms of structure, size, and frequency of access. When to use SQL database over non-relational database Value can be a string, number, boolean, or an array.A key/value pair consists of a field name (in double quotes), followed by a colon, followed by a value.Data in a JSON document is stored in key/value pairs.This is the reason it became a very popular format for storing and exchanging data between software systems. JSON format is text-based and both humans and machines can very easily read it. In the following JSON document we have student data. What is JSON : The acronym JSON stands for JavaScript Object Notation. ![]() ![]() BSON is Binary JSON, so first let's understand, what is JSON? So data in MongoDB is stored in BSON documents. In MongoDB we do not have tables, instead we have documents. In a relational database like SQL server data is stored in a table, obviously in rows and columns. ![]() At the end of the day, MongoDB is a database and we use it to store data. It's important to understand the difference between JSON and BSON. Difference between JSON and BSON in MongoDB ![]()
