So, you can assume the collections to be your tables and the Documents to be your fields in the tables.Īlright, So, now that you know what is SQL & NoSQL, let us now see, how these databases stand against each other. Now, each of these collections has Documents, which are basically the data values. Consider the example below.Īs you can see from the above image, there is an Employee Database which has 2 collections i.e. So, a database can have a ‘n’ number of collections and each collection can have ‘m ‘ number of documents. So, a NoSQL database has no specific query language, no or a very few relationships, but has data stored in the format of collections and documents.
This type of database can handle a humongous amount of data and has a dynamic schema. NoSQL, or most commonly known as Not only SQL database, provides a mechanism for storage and retrieval of unstructured data. Now, next in this article let us understand what is NoSQL? What is NoSQL?
A Self -Referencing Relationship is when a record in table A is related to the same table itself.A Many-to-Many Relationship is when many rows in table A can be related to many rows in table B.A One-to-Many Relationship is when a single row in Table A is related to many rows in table B.A One-to-One Relationship is when a single row in Table A is related to a single row in Table B.This language is used to manipulate and retrieve data from a structured data format in the form of tables and holds relationships between those tables. SQL aka Structured Query Language is the core of the relational database which is used for accessing and managing the databases. So, let us get started, folks!! What is SQL? Demo: Insert values into tables and collections.The following topics will be covered in this article: So, in this article on SQL vs NoSQL, I will compare these two type of databases to help you choose which type of database can help you and your organization. In today’s market, there are different kinds of databases present, and deciding on the best database which suits your business can be an overwhelming task. With the amount of data present in the world, it is almost next to impossible, to manage data without proper databases.
