What is the difference between rem and echo in batch?
rem is a comment that is only seen if you edit the batch echo actually is printed when the batch is running
What is batch data processing mode?
Batch processing generally means using a scripting language to queue one or more jobs that will work one after the other without any manual intervention. That is, the actual processing is automated, the only input required from the user is in order to set up the batch. Contrast with online or interactive data processing which requires user-input throughout the process. In batch processing, the input is typically generated from input files collated as a batch, and the output of one job can often be used as input for the next job, dependant upon the type of processing. Some software includes batch processing modes of their own, but for those that don't, command sequences can be crafted using scripting languages, either from within the program itself (where supported) or externally at operating system level. Operating system command scripts can also be employed for batch processing, hence they are also known as batch files.
What are examples of batch processing?
Batch processing enables work to be done simultaniously whilst the workers are able to play football in the courtyard whilst production is taking place. this can occur in the workplace and is highly recommended to anyone who wishes to try this. An example of batch processing is the way that credit card companies process billing. The customer does not receive a bill for each separate credit card purchase but one monthly bill for all of that month's purchases. The bill is created through batch processing, where all of the data are collected and held until the bill is processed as a batch at the end of the billing cycle.
What is the best method of data processing?
There are different methods of data processing. Some methods are manual data processing, mechanical data processing, online processing, batch processing and electrical data processing.
What is the difference between online processing and realtime processing?
Ah, online processing and real-time processing are like two happy little trees in the same forest. Online processing typically involves batch processing where data is collected and then processed in intervals, while real-time processing happens instantly as data is received. Both methods have their own beauty and purpose, just like different brushstrokes on a canvas.
