Information Systems are developed to help users to achieve their goals. If we look at the international level, the introduction of information technology and general information systems in everyday life, we will see that this admission has been made successfull by-producing the expected results in countries characterized by good organization of public life other, individual systems, banking system, health system, are well organized and staffed.
On the other hand, Decision Support Systems represent a combined approach of decision making from the Administration area with tools and IT techniques. A widely accepted definition describes the DSS as computer software which accepts as input data a large number of events and methods to convert comparisons, graphs and directions in some sense, that facilitate and expand the capabilities of what takes decisions.

Excerpt from the Book
1. What are Information Systems
Information (Information) is any form of communication, which provides comprehensive and money-level- knowledge to the person who takes it. In other words, the information is data that are structured to be easily understandable and useful to people. Data are the raw material of each IT system and form the basis for the setting-miourgia information [11].
As a system can be defined a number of related elements which perform an activity, function or task. The systems are divided into open and closed. Open called the systems affected by the environment (or affect) and closed called those not affected by the environment, nor the influence. The information systems are open systems because process information from their environment, not process the information available to them [12].
The open and closed systems differ in their entropy. Entropy is the concept by which you measure the "disorder", whose maximum value reflects the total disarray and is equivalent to the termination of life or otherwise of evolution [9]. In open systems, the "order" and therefore its entropy remains constant, increases or decreases depending on the input (input) of the maintenance. In closed systems, the entropy never reduced because they are not maintenance input. In the area of information systems, the term open system mainly refers to those systems that Bo-Rooney to work with software (software), and equipment (hardware) from various procure-ers, and the term closed to those which can operate software and equipmention from a single supplier. It is understood that the open systems are more flexible and the current trend is the dynamic movement from closed to open systems.
Summary of Chapters
1. What are Information Systems: Defines the core concepts of information, data, and system types, explaining the distinction between open and closed systems in an organizational context.
2. What decision: Outlines the process of decision-making, identifying the stages involved and providing a definition of Decision Support Systems as tools to enhance these processes.
3. The Decision Support System features: Discusses the technical components, historical progression, and practical challenges of implementing DSS, including factors that affect their successful adoption.
4. Conclusions: Synthesizes the importance of integrating DSS into everyday business practice to reduce errors and improve overall service quality.

Frequently Asked Questions
What is the core subject of this publication?
The publication examines the functional role of Information Systems and the specialized use of Decision Support Systems to facilitate complex business decision-making processes.
What are the central themes discussed in this text?
The main themes include the definition of system architectures, the mechanics of decision-making, the technological components of modern IT systems, and the socio-technical challenges of system adoption.
What is the primary goal of the research presented?
The goal is to analyze how technology can be used to augment human decision-making and identify the factors that contribute to the successful deployment of decision support tools in organizations.
Which scientific methodology is primarily employed?
The text utilizes a literature-based theoretical analysis to define system concepts and reviews historical evolution and practical application criteria to assess the viability of DSS.
What topics are covered in the main section?
The main section covers the architectural structure of DSS, the role of knowledge bases and explanation engines, and a comparative study of multicriteria analysis methods.
Which keywords best characterize this work?
Key terms include Information Systems, Decision Support Systems, Knowledge Management, System Architecture, and Organizational Decision Making.
How do open and closed systems differ in an IT context?
Open systems interact with their environment and offer greater flexibility by integrating hardware and software from various suppliers, whereas closed systems are typically restricted to single-supplier ecosystems.
Why is the human factor considered critical in DSS implementation?
The human factor is critical because personnel may resist the implementation of new systems, fearing job replacement or finding user interfaces too complex, despite the tools being designed to assist them.
What is the role of the "knowledge base" in a DSS?
The knowledge base is described as the most important component of a DSS, as it acts as the repository for all relevant data and logical relationships necessary to synthesize optimal solutions.
How does the text define the historical evolution of DSS?
The text traces the progression from simple individual decision support to complex networked systems, including Executive Information Systems (EIS) and group-based support (GDSS).
