📌 Event-Driven Architecture Summary

Event-Driven Architecture is a software design pattern where different parts of a system communicate by sending and responding to events. Instead of constantly checking for changes, components react when something specific happens, like a user clicking a button or a payment being made. This approach can help systems become more flexible and able to handle many tasks at once.

🙋🏻‍♂️ Explain Event-Driven Architecture Simply

Imagine a school bell ringing to signal class changes. Instead of each teacher checking the clock, they just wait for the bell and act when it rings. In event-driven architecture, software parts wait for their own bell, or event, and respond only when it happens. This makes things run more smoothly and efficiently.

📅 How Can it be used?

You could use event-driven architecture to let different microservices in an online store react instantly to orders, stock changes, and customer actions.

🗺️ Real World Examples

In online banking, when a customer makes a payment, an event is triggered. This event notifies other parts of the system to update the account balance, send a confirmation message, and log the transaction, all without manual intervention.

A ride-sharing app uses event-driven architecture so that when a driver accepts a ride, an event is sent to update the passenger, adjust the driver’s status, and start the trip tracking, keeping everything in sync in real time.

✅ FAQ

Event-driven architecture is a way of designing software so that different parts of a system talk to each other by sending messages when something happens, like a button being clicked or a payment going through. Instead of constantly checking for updates, each part simply reacts when it needs to, making systems more flexible and efficient.

Developers use event-driven architecture because it helps systems handle lots of things at the same time without getting bogged down. By reacting only when specific events occur, it makes it easier to add new features and makes the system more responsive to users.

Yes, event-driven architecture can help apps feel faster and more responsive. Because the different parts of the system only act when needed, there is less waiting around and fewer unnecessary checks, which can speed up how quickly things happen for the user.

Digital Maturity Assessment

A Digital Maturity Assessment is a process that helps organisations understand how effectively they are using digital tools, technologies and processes. It evaluates areas such as leadership, culture, customer experience, operations and technology to see how advanced or prepared a business is for digital change. The results offer a clear picture of strengths and areas for improvement, guiding future digital strategies.

Scriptless Scripts

Scriptless scripts refer to automated testing methods that do not require testers to write traditional code-based scripts. Instead, testers can use visual interfaces, drag-and-drop tools, or natural language instructions to create and manage tests. This approach aims to make automation more accessible to people without programming skills and reduce the maintenance effort needed for test scripts.

Model Lag

Model lag refers to the delay between when a machine learning model is trained and when it is actually used to make predictions. This gap means the model might not reflect the latest data or trends, which can reduce its accuracy. Model lag is especially important in fast-changing environments where new information quickly becomes available.

Prompt Dependency Injection

Prompt Dependency Injection is a technique used in AI and software development where specific information or context is added into a prompt before it is given to an AI model. This method helps guide the AI to produce more accurate or relevant outputs by supplying it with the necessary background or data. It is often used to customise responses for different users, situations, or tasks by programmatically inserting details into the prompt.

AI for Mental Wellness

AI for Mental Wellness refers to the use of artificial intelligence technologies to support, monitor, or improve mental health. These tools can analyse data from text, speech, or behaviour to detect signs of stress, anxiety, or depression. They may also offer recommendations, reminders, or coping strategies to help individuals manage their mental wellbeing.
