The RedisBank application is an online banking platform that utilizes Redis, a fast and accurate data store, to provide real-time access to financial information. The app allows users to monitor and plan their finances accurately by using Redis core data structures and modules, such as Redis Streams, Sorted Set, TimeSeries, and Hashes. The application also uses Spring Boot APIs and a frontend, and is built on top of the Redis module for Spring. The app generates bank transactions every 10 seconds or so and puts them in a Stream, which is then processed by the app and sent to the user interface. It also adds every transaction to a Sorted Set, allowing users to identify the biggest spenders. Additionally, the app uses TimeSeries to store bank account balances and Hashes to index transactions for search functionality. The application provides real-time data transmission, eliminating lags, and allows users to access their banking information with just a few taps on their mobile device.
