How does a stack trace work?

Simply put, a stack trace is a representation of a call stack at a certain point in time, with each element representing a method invocation. The stack trace contains all invocations from the start of a thread until the point it’s generated. This is usually a position at which an exception takes place.

What is stack trace in database?

In computing, a stack trace (also called stack backtrace or stack traceback) is a report of the active stack frames at a certain point in time during the execution of a program. When a program is run, memory is often dynamically allocated in two places; the stack and the heap.
