📌 Data Cleansing Summary
Data cleansing is the process of detecting and correcting errors or inconsistencies in data to improve its quality.

Clean data helps organisations make better decisions and reduces the risk of mistakes caused by incorrect information.
🙋🏻♂️ Explain Data Cleansing Simply
Imagine you are organising your music playlist. You might find songs with the wrong titles, missing album names, or duplicate tracks. Data cleansing is like fixing all these mistakes so your playlist is neat and easy to use. Just like a tidy playlist helps you find and enjoy your music, clean data helps people trust and use information more effectively.
📅 How Can it be used?
Data cleansing can be used to prepare customer information before launching a targeted email marketing campaign.
🗺️ Real World Examples
A hospital collects patient records from different departments, but some names are misspelt and addresses are incomplete. Data cleansing is used to correct spelling, standardise address formats, and remove duplicate records so that patient information is accurate for medical staff.
An online retailer wants to analyse sales data, but the product names are inconsistent and some entries are missing prices. Data cleansing is applied to standardise product names and fill in missing prices, making the data ready for accurate sales analysis.

Session Token Rotation
Session token rotation is a security practice where session tokens, which are used to keep users logged in to a website or app, are regularly replaced with new ones. This reduces the risk that someone could steal and misuse a session token if it is intercepted or leaked. By rotating tokens, systems limit the time a stolen token would remain valid, making it harder for attackers to gain access to user accounts.
AI for Compliance
AI for Compliance refers to the use of artificial intelligence technologies to help organisations meet legal, regulatory, and internal policy requirements. It automates tasks such as monitoring transactions, analysing documents, and detecting unusual behaviour that might indicate non-compliance. This helps reduce human error, speeds up processes, and ensures rules are consistently followed.
Cross-Chain Atomic Swaps
Cross-chain atomic swaps are a technology that allows people to directly exchange cryptocurrencies from different blockchains without needing a central exchange or trusted third party. These swaps use special smart contracts to ensure that either both parties get what they agreed to or nothing happens at all. This process increases security and privacy, as users keep control of their funds throughout the exchange.
Enterprise Service Bus
An Enterprise Service Bus (ESB) is a software system that helps different computer programmes within a company communicate and share data. It acts as a central hub, allowing various applications to connect without needing to know the technical details of each other. By using an ESB, businesses can integrate their systems more easily, making it simpler to update or replace individual parts without disrupting the whole network.
Data Loss Prevention Strategy
A Data Loss Prevention Strategy is a set of policies and tools designed to stop sensitive data from being lost, stolen or accessed by unauthorised people. It helps organisations identify, monitor and protect important information such as financial records, personal details or intellectual property. This strategy often uses software that scans for confidential data and sets rules for how it can be shared or moved, reducing the risk of accidental leaks or intentional theft.
