Database Query Repository:

Welcome to the Database Query Repository! This repository serves as a comprehensive collection of queries and examples related to various databases that I have utilized throughout my experience.

The covered databases include:

MongoDB: A NoSQL database known for its flexibility and scalability.

MySQL: A powerful relational database management system widely used for structured data.

DynamoDB: A fully managed NoSQL database service provided by Amazon Web Services (AWS), offering seamless scalability.

Redis: An in-memory data structure store used as a database, cache, and message broker.

PostgreSQL : It is a powerful, open source object-relational database system that uses and extends the SQL language combined with many features that safely store and scale the most complicated data workloads.
