How it's made

Challenges we ran into During the development of our project, BankWave: Empowering Your Finances Online, we encountered several challenges and bugs that required innovative solutions and problem-solving. One specific hurdle we faced and successfully overcame was related to handling concurrent transactions and ensuring data consistency in the system. The primary issue we encountered was a race condition when multiple users attempted to perform transactions simultaneously, such as transferring funds between accounts or making deposits and withdrawals. This race condition could potentially result in incorrect balance updates, data corruption, or even financial discrepancies for users. It was a significant bug that needed immediate attention. To address this challenge, we employed a combination of strategies: Database Locking Mechanism: We implemented a database locking mechanism to ensure that only one transaction could access a specific user's account at any given time. This was achieved by using the synchronized keyword in Java when interacting with the database. It ensured that no two transactions could access the same account simultaneously, preventing data inconsistencies. Transaction Queuing: To manage concurrent transaction requests, we implemented a transaction queue. When a user initiated a transaction, it was placed in a queue, and each transaction was processed sequentially. This approach guaranteed that transactions were processed one by one, eliminating the possibility of conflicts. Logging and Monitoring: Implementing robust logging and monitoring tools allowed us to track and diagnose any unexpected behavior or errors during concurrent transactions. This was crucial for identifying and addressing issues in real-time.
