AI Thread Summary
Banks utilize batch processing to manage data updates by sorting update data and then copying it to a secondary file for database updates. This process typically involves sequential I/O, which allows for the use of magnetic tape storage. The sorting of update data can be efficiently executed using multiple tape drives through a merge sort technique. The discussion emphasizes the distinction between real-time database updates and those conducted in batches, suggesting a need for clarity in the original inquiry about data storage methods in banks.

Can anyone tell me how does the bank store data in the system of batch processing?

I'm not sure what you're trying to ask. Wiki article for batch processing:

I'm also not sure on what you mean how a bank stores data. Databases are usually designed to work with real time updates, but in the case of a database that is only updated via a batch process, the update data could be sorted, and then the database copied and updated to a second file, using the sorted update data. Everything but the sorting of the update data would involve sequential I/O (which would allow the database to be stored on magnetic tape). The sorting of the update data could also be done on multiple tape drives (at least 3), using a merge sort.

I don't think this is the answer you're looking for, so perhaps you could reword your original question.

Thread 'Is this public key encryption?'

I've tried to intuit public key encryption but never quite managed. But this seems to wrap it up in a bow. This seems to be a very elegant way of transmitting a message publicly that only the sender and receiver can decipher. Is this how PKE works? No, it cant be. In the above case, the requester knows the target's "secret" key - because they have his ID, and therefore knows his birthdate.

Thread 'Project Documentation'

Trying to package up a small bank account manager project that I have been tempering on for a while. One that is certainly worth something to me. Although I have created methods to whip up quick documents with all fields and properties. I would like something better to reference in order to express the mechanical functions. It is unclear to me about any standardized format for code documentation that exists. I have tried object orientated diagrams with shapes to try and express the...
