📌 Event-Driven Architecture Summary
Event-Driven Architecture (EDA) is a software design pattern where systems communicate by producing and responding to events. Instead of following a strict sequence, different parts of the system react whenever something happens, such as a user action or a change in data. This approach allows systems to be more flexible, scalable and easier to update, as new features can be added by simply listening to new events without changing the entire system.
🙋🏻♂️ Explain Event-Driven Architecture Simply
Imagine a group chat where anyone can send a message and others can choose to reply or ignore it. Each person reacts when they receive a message that interests them, instead of waiting for their turn. In event-driven architecture, different parts of a system pay attention to specific events and act only when something relevant happens.
📅 How Can it be used?
You could use event-driven architecture to build a notification system that sends alerts whenever users receive new messages or updates.
🗺️ Real World Examples
Online retailers use event-driven architecture to update inventory and notify customers. When an item is purchased, an event is triggered, updating available stock and sending confirmation emails without slowing down the checkout process.
Banks often use event-driven architecture for fraud detection. Each transaction triggers an event that can be analysed in real time, allowing the system to quickly react and alert staff or customers if suspicious activity is detected.

💡Other Useful Knowledge Cards
Integer Overflow Exploits
Integer overflow exploits are a type of software vulnerability where a computer program does not properly handle numbers that are too large or too small for the allocated storage space. When this happens, the value can wrap around to a much smaller or negative number, causing unexpected behaviour. Attackers can use this flaw to bypass security checks, crash programmes, or even run malicious code.
Data Imputation Strategies
Data imputation strategies are methods used to fill in missing or incomplete data within a dataset. Instead of leaving gaps, these strategies use various techniques to estimate and replace missing values, helping maintain the quality and usefulness of the data. Common approaches include using averages, the most frequent value, or predictions based on other available information.
Decentralized Consensus Models
Decentralised consensus models are systems that allow many independent computers to agree on the same data or decision without needing a single central authority. These models help ensure that everyone in a network can trust the shared information, even if some members are unknown or do not trust each other. They are a fundamental part of technologies like blockchains, enabling secure and transparent record-keeping across distributed networks.
Prompt Flow Builder
A Prompt Flow Builder is a tool that helps users design and organise sequences of prompts for AI models. It allows people to visually map out how different prompts and responses connect, making it easier to create complex workflows for chatbots, virtual assistants, or automated systems. By using a Prompt Flow Builder, users can test, adjust, and optimise their prompt chains without needing to write code.
Structured Prompt Testing Sets
Structured prompt testing sets are organised collections of input prompts and expected outputs used to systematically test and evaluate AI language models. These sets help developers check how well the model responds to different instructions, scenarios, or questions. By using structured sets, it is easier to spot errors, inconsistencies, or biases in the model's behaviour.
