Thank you for the opportunity to help you with your question!
When you ask of various systems that are used by businesses and profit or non-profit organizations, we talk about information systems.Currently there are database servers to hold large quantities of data, mail servers to hold a large quantity of email communications, files and folders on personal computers, and you have the cloud, which is another kind of storage on the internet outside of the private network.
I think companies these days use cloud computing, because data storage on the internet is most often free.
But in a more structured way, information systems have hierarchies and categories.
We consider 3 categories of information systems: Senior Management, Middle Management, and Operational Management.
1.) Senior Management is actually the control center. Often called strategic management, it includes the data from Executives and directors.
2.) Middle Management have control over other systems but follow orders from Senior Management. They deal with information management. Middle management is called tactical management and they consist of Business unit managers or self-directed teams. Their data may be password protected in the network, so that they or senior management is allowed to access it.
3.) Operational Management controls the transaction processing systems. They include operations managers and self-directed teams.
