In earlier days, applications contained well-defined schema with relationships, So SQL database (DB) is suitable. Nowadays, applications are required to store unstructured data (Eg: image, key-value, time-related data) and distribute the data across multiple servers and faster response time. So NoSQL databases are preferable Types of NoSQL: 1. Document-based (MongoDB) 2. Key-Value Stores (Redis) 3. Graph (Neo4j) 4. Time Series-based (InfluxDB) It is essential to understand where to use traditional RDBMS and where to use NoSQL. So that you can fetch the data effectively and efficiently. You can these gain via the following steps: 1. Working on the project 2. Online Course 3. Competition - while working with large DB (#kaggle)

As a database engineer, proficiency in SQL alone is insufficient. Understanding database modeling is equally crucial. Begin by studying concepts like relationships, entities, and attributes. Then delve into the database design process, ensuring that your models align with business needs and objectives. Ultimately, the goal is to create robust database structures that effectively support and optimize business operations
