Hi @alif,

Welcome to Google Cloud Community!

Is there any specific product related to GCP Database you want to know more about? To answer your questions there are many reasons behind the use of NoSQL depending where they used it.

The primary common reasons for using NoSQL databases are their performance, scalability, and flexibility. They are excellent for dynamic or unstructured data since they can expand across several servers, handle massive amounts of data, and don't require a predefined schema. Additionally, they provide fault tolerance and high availability, which are essential for large data, real-time applications, and systems that require quick access to data. When managing complex data models, speed, and flexibility are crucial, NoSQL is frequently the preferred option.

Hi @alif,

NoSQL databases generally do not require a fixed schema. This allows developers to store semi-structured or unstructured data, such as JSON documents, key-value pairs, or graph data.

NoSQL databases like Firestore and Bigtable can be more cost-effective than traditional relational databases (e.g., Cloud SQL) for certain workloads, especially when dealing with large-scale, low-latency data storage or when the schema is highly variable.

NoSQL databases are used in GCP to meet the needs of modern applications that require scalability, flexibility, performance, and real-time capabilities. GCP's managed NoSQL offerings, such as Firestore and Bigtable, enable developers to focus on building applications without worrying about managing infrastructure, while also taking advantage of the platform’s robust ecosystem for data processing, analytics, and machine learning.
