Theory and Pratice of information Systems


The course mainly aims at analyzing the information systems in the context of organizations, separating the technological aspects of the organizational aspects and management. It will examine the following topics: -Characterization of systemic Organizations -Structured Analysis -Planning of information systems Architectures-information systems At the end of this unit the student should be able to:

LO1 - Conceptualize organizations systems as information systems, ie, be able to apply the basic concepts of Systems Theory and Information Theory in information systems management from the real world

LO2-Perform Entity Active Systemic analysis

LO3-Mastering a method of Functional Analysis

LO4-Know the Information Systems Planning main approaches

LO5-Know and apply the different types and referential of Information Systems architecture

Teaching method

Teaching based on lectures and practical classes. The lectures are, in essence, for expository sessions, which serve to introduce the fundamental concepts associated with each of the topics. The practical classes are based on the analysis, modeling and planning organizations and implementation of theoretical concepts.

Teaching Methods

¿ Expository and interrogative teaching:lectures and discussions.

¿ Declarative:tutorials tools

¿ Active and participative:case studies, participation in project teams and practical use of theoretical concepts of Information Systems


Evaluation method


1st round:Theoretical test (50%) + 3 Practicals Works (50%)

2nd round:final exam (100%).
