Accounting Information Systems: An Overview
The ’systems’ concept was created in order to minimize common errors such as duplications and, overall, encourage ‘integration’. Systems are almost always composed of subsystems, which are in charge of specific functions needed to support the larger organism. Subsystems are expected to follow the main organization’s goals even if it implies not meeting their specific targets. The value of the information reported by an entity is the difference between the benefit obtained from that organized data, minus the cost of implementing an Accounting Information System in charge of collecting, recording, storing and processing the data.
