Abstract: The purpose of a data model is to describe logic structure of the object system, as it is looked by his users. In Accounting Information Systems, the object is the economic entrepreneur and the information stored which is needed in a structural way so the data may be consistent and integrated.
Reality modeling of the components around the economic unit is very important for building an efcient system which stores the information about the economic unit.
In the beginning of Accounting Information Systems modeling of the data was made by materializing the processes of the economic unit into process which the computer may process fast and with fewer errors than humans. This model didn’t take into consideration the structure of traditional data of the discipline of accounting. They stored the model intact as it was described by
Pacioli during

So the statements are just converted in virtual views that contains the information processed and is viewed as many times as the user need.
Beginning from the
