Question

Quizplus · Accepted Answer

Sequential-access files are useful in batch processing, where large volumes of data are processed in batches. In batch processing, data is processed in sequential order, and sequential-access files are ideal for this purpose. They are also useful when the data in the file is sorted in a specific order, such as by date or time, allowing for easy retrieval of data. However, they are generally not ideal for situations where random access to data is required, such as in a database or accounts receivable master file.
