what is ERP? why inventory comes in ERP?

Answer

A. Enterprise Resource Planning software, or ERP, doesn't
live up to its acronym. Forget about planning?it doesn't do
much of that?and forget about resource, a throwaway term.
But remember the enterprise part. This is ERP's true
ambition. It attempts to integrate all departments and
functions across a company onto a single computer system
that can serve all those different departments' particular
needs.
B.
Building a single software program that serves the needs of
people in finance as well as it does the people in human
resources and in the warehouse. Each of those departments
typically has its own computer system optimized for the
particular ways that the department does its work. But ERP
combines them all together into a single, integrated
software program that runs off a single database so that the
various departments can more easily share information and
communicate with each other. thats why it has the inventory.

what is tracebility matrix? what is negative testing

Answer

A traceability matrix documents the following:-
1. User and functional requirements.
2. Design specifications that address each user requirement.
3. Testing references (i.e., Operational, and User
Acceptance) and specific objectives or Standard
Operations Procedures (SOPs)which verify that the user
requirements have
been met.

B. "Testing aimed at showing software does not work", is
called negative testing.
Each test in negative testing needs two elements:-
1)to show that the software will fail
2)the failure is handled in a specified manner
