How do ACID and database transactions work?

Question

What is the relationship between ACID and database transaction?

Does ACID give database transaction or is it the same thing?

Could someone enlighten this top

Answer 1

I slightly modified the printer example to make it more explainable

1 document which had 2 pages content was sent to printer

Transaction - document sent to printer

• atomicity - printer prints 2 pages of a document or none
• consistency - printer prints half page and the page gets stuck. The printer restarts itself and prints 2 pages with all content
• isolation - while there were too many print outs in progress - printer prints the right content of the document
• durability - while printing, there was a power cut- printer again prints documents without any errors

Hope this helps someone to get the hang of the concept of ACID
