In view of the above, here we are at the end of the Information Analysis Study Method I course. The aim is to represent the information circulating in a certain Company by means of models based on three levels of abstraction. It is important, and even extremely important, to note that this book is approached in the first part, that of the study of the existing situation, through the construction of a conceptual data model, the conceptual processing model and finally the organizational processing model. At the start of this syllabus, we emphasized the simple fact that we are not detailing the different parts of an analysis (MERISE) here, as this will have its effect in the second part, that relating to the design of the IIS, which is the computerized information system. In the latter, we are now thinking about the implementation of an application that we need to develop. As part of their undergraduate coursework, students will start by studying the existing situation and building the Organizational Processing Model, since this is the model that fully reflects the company's reality.
