What is Scheduled and Batch classes?

Scheduled and Batch classes are programming constructs used to execute tasks automatically at predetermined times or in bulk, respectively. Scheduled classes allow for the automation of routine tasks, such as data backups or report generation, by running code at specified intervals (e.g., daily, weekly). Batch classes are designed to process large volumes of data asynchronously, breaking down the work into smaller, manageable chunks to avoid exceeding system limits. They are commonly used for data cleansing, complex calculations, or large-scale data migrations.
