Data filters are tools used in data management and analysis to selectively display or process information based on specific criteria. They help users focus on relevant data by hiding or excluding unwanted information, making it easier to analyze trends, patterns, or insights. Common applications of data filters can be found in software like Excel or SQL databases. By applying data filters, users can streamline their workflow and improve decision-making. For instance, a business might filter sales data to view only transactions from a particular region or time period. This targeted approach enhances clarity and efficiency in data handling.
