This project is a simple banking app that uses a microservice architecture and Go on the backend.

 

The following principles were followed during DB design.

• Atomicity: Either all operations complete successfully or the transaction fails and db is unchanged.
• Consistency: The DB state must be valid after the transaction and all constraints satisfied.
• Isolation: Concurrent transactions must not affect each other.
• Durability: Data written by a successful transaction must be recorded in persistent storage.

This was done to avoid the following read phenomena:

• Dirty reads caused by read-uncommitted isolation level
• Non-repeatable reads
• Phantom reads
• Serialization Anomaly
