CAP Theorem, formulated by computer scientist Eric Brewer, states that in a distributed system, it is impossible to simultaneously achieve Consistency, Availability, and Partition Tolerance. In the event of network partitions, a trade-off must be made between maintaining consistency and ensuring system availability. This theorem is fundamental in designing and understanding distributed databases and systems.

Database systems refer to organized and structured collections of data, typically stored electronically. They are designed to efficiently manage, store, and retrieve information, providing a centralized repository for various applications. Database systems use software to define the data structure, facilitate data manipulation, and support secure and controlled access to the stored information, enabling effective data management in diverse contexts.

The CAP theorem, also known as Brewer’s theorem, is a concept in distributed systems and database design that describes the trade-offs between three key properties: Consistency, Availability, and Partition Tolerance. According to the CAP theorem, in a distributed database system, it is impossible to achieve all three of these properties simultaneously.

It’s important to note that the CAP theorem doesn’t prescribe a specific choice but highlights the inherent trade-offs in distributed systems. The optimal choice depends on the specific requirements and use cases of the application. Some distributed databases and systems, such as NoSQL databases, are designed with a focus on AP characteristics, while others, like traditional relational databases, may prioritize CA characteristics.

• Consistency (C):

Consistency in the context of the CAP theorem means that all nodes in a distributed system see the same data at the same time. In other words, when a change is made to the data, all nodes are updated simultaneously. Achieving consistency ensures that all users, regardless of the node they are connected to, observe a consistent view of the data.

• Availability (A):

Availability refers to the guarantee that every request made to the distributed system receives a response, without the guarantee that it contains the most recent version of the data. An available system continues to operate and respond to requests even in the face of node failures or network partitions.

• Partition Tolerance (P):

Partition Tolerance addresses the system’s ability to continue functioning even when network partitions (communication failures) occur between nodes in the distributed system. In practical terms, partition tolerance means that the system can handle and continue to operate even if some nodes are temporarily unreachable or if network messages are lost.

The CAP theorem asserts that it’s impossible to simultaneously achieve all three properties—Consistency, Availability, and Partition Tolerance—in a distributed system. A distributed system can only provide two out of the three, creating a set of trade-offs that developers and architects must consider when designing and deploying distributed databases. Here are the three classic scenarios defined by the CAP theorem:

• CA (Consistency and Availability, no Partition Tolerance):

In a CA system, consistency is prioritized, and all nodes in the distributed system are guaranteed to have the most recent version of the data at all times. This comes at the cost of availability in the face of network partitions. If a partition occurs, the system may become unavailable.

• CP (Consistency and Partition Tolerance, sacrificing Availability):

A CP system ensures consistency and partition tolerance, but availability may be compromised. If a network partition occurs, the system might choose to become temporarily unavailable rather than risk delivering inconsistent data.

• AP (Availability and Partition Tolerance, sacrificing Consistency):

In an AP system, availability is prioritized, meaning that the system continues to operate and respond to requests even in the presence of network partitions. However, this may result in eventual consistency, where different nodes may have different views of the data for a period.
