Kathrine Sathi RHello everyone,
The world is filled with data. Everything today is data and it's huge to store, manage, and retrieve. How are we going to manage everything? Here comes the Queen, where the data is being managed and stored. Her name is Database. In our day-to-day lives, it is challenging to manage this huge data. So how are we gonna manage this database, and here comes another queen who is the sister of Database is Database management system.
And the connection between these two queens who are the mother of the entire thing is SQL
P.S.: It's good when we tell these things as a story. Moving into a serious tone from here.
SQL: Structured Query Language, which is a bridge between database and database management systems. SQL is used to create, update, store, and retrieve data from the database.
Data can be in three types:
- Structured data - The data which is in the table format.
- Unstructured data - The data which is present in the social media
- Semi-structured data - The data that is present in our emails
The **database **can be in four types:
- Relational Database
- Non - Relational Database
- Hierarchical Database
NOSQL will deal with the data which has many data structures including columns, documents, and key-value pairs.
Thanks for reading my blog, Happy learning. Will meet you in the upcoming blogs!
