DefinitionBatch processing (バッチ処理) is a processing mode that stores data until a set period or count is reached and then processes it all at once.
ExplanationIt suits processing that does not need a response for each item and clears large volumes of data efficiently. Totaling a month of sales slips on the closing date, or running work together at night when usage is low, are examples. One unit of work that a computer is given to run as a whole is called a job (ジョブ), and batch processing runs several jobs in a set order.
AnalogyIt is like piling laundry in a basket and running the washing machine once when the basket is full.
Memory hookA batch originally meant one oven load of bread. Link it to gathering everything for one baking before it goes into the oven.
