Before sorting and filtering data in a database, you need to ensure that the data is organized in a tabular format, with each row representing a single record and each column representing a specific attribute. You also need to have a clear understanding of the criteria you will use to sort and filter the data. Finally, you may need to create indexes on the columns you intend to sort or filter for optimal performance.
