What are the advantages of NoSQL compared to SQL?

Main advantages of NoSQL over SQL:

• Flexible data schema: Does not require a strictly predefined schema, simplifying iterative development and working with unstructured data.
• Scalability: Horizontal scaling (adding more servers) is much easier and cheaper compared to vertical scaling in SQL.
• Performance: Often higher read/write speeds for specific data types and queries due to the use of various data models (document-oriented, key-value, etc.).
• Handling large volumes of data: Better suited for storing and processing petabytes of data distributed across a cluster.
• Variety of data models: Allows choosing the most suitable model for a specific task (e.g., graph for social connections, document for JSON-like data).

However, it should be noted that NoSQL is not a replacement for SQL in all cases. SQL surpasses NoSQL in the following aspects:

• Transactions (ACID): Guarantees data integrity during complex transactions.
• Complex queries: Enables executing complex queries with joins and filtering across multiple tables.
• Standardization: SQL is a standard, making it easier to learn and use different DBMSs.

The choice between SQL and NoSQL depends on the specific project requirements.
