Item grouping is a method used to organize similar items together based on shared characteristics. This can include grouping products in a store by category, such as electronics, clothing, or furniture. By categorizing items, it becomes easier for customers to find what they need and for businesses to manage inventory efficiently. In data management, item grouping helps in analyzing trends and patterns. For example, a company might group sales data by region or time period to understand performance better. This approach aids in decision-making and strategic planning, allowing organizations to respond effectively to market demands.
