The SIM class attendance system is indeed a transaction processing system, but because it makes no decisions, you cannot use it as an example for structured decision making.

I don't understand what you mean by "companies using 1 of the above 4 classes of IS".  It depends entirely on the needs and resources available to companies.  In any case, forget about semi-structured decision systems.  Just understand the difference between structured and unstructured decision making.  Semi-structured is generally considered as unstructured decision-making, anyway.

Dear mr toh,

Noted. Also is 'class attendance system' an example of TPS class of information system? 

Under semi-structured, the class of information system used can be knowledge work systems, decision support system, office automation systems and management information systems. 

Will companies be using 1 of the above 4 class of IS? And when we discuss in essay, we can choose 1 out of the 4 IS to discuss? 

Thank you.

Thanks.
