Exchange Data

An information system (IS) is a system that communicates, transforms, and preserves information for human users. An information system comprises one or more software applications and databases, and their relationships to their human users, operators, and maintainers. A modern enterprise has many information systems that can be related in various ways. For example, information systems can be related by exchange because they exchange data through message passing or shared databases, or because they exchange functions through remote procedure calls or Web services. Information systems can also be related by overlap because they maintain the same data or provide the same functions. Information systems can be related in many other ways too, either directly, such as when one IS controls another, or indirectly, for example, because several ISs depend on the same run-time platforms or because they compete for their users’ attention or for computer resources. In addition to being related to one another, information systems can be related to the surrounding organization in many ways. For example, organization units such as departments, individuals, or roles may be the owners, users, operators, or maintainers of ISs; organizational goals and strategies can be realized by ISs; organizational processes can be supported or automated by ISs; and so on. The information systems (IS) architecture of an enterprise comprises its information systems, the relationships between those information systems, and their relationships to the surrounding organization. In addition to single enterprises, alliances of enterprises and parts of enterprises, such as divisions and departments, can have IS-architectures too. The above definition implies that every enterprise has an ISarchitecture, even if that architecture is not explicitly talked about, described, or managed: ‘IS-architecture’ is a way to look at organizations and their information systems.1 IS-architecture alignment is the process of selecting an IS-architecture vision towards which the architecture should be incrementally but systematically evolved. This article will present a model-supported framework for aligning an IS-architecture with its surrounding organization (Opdahl, 2003a). The framework shows how an enterprise’s current IS-architecture can be represented in an enterprise model, from which candidate architecture visions can then be generated, before one of them is selected as the enterprise’s IS-architecture vision.

Uml Models

The Language-Action Perspective provides a communicative view on the organization. In it an organization is characterized as a system of interacting agents. This view is helpful in understanding how the organization works and it can also contribute to the design of information systems in support of it. This design is often done in UML, a language that views an information system as a system of message-passing objects. We suggest an approach to support this design by mapping action models onto UML models

Data Level

An information system is a multilevel system characterized by a “data” level, a “behavioral” level, and a “communication” level. The data level represents the data stored by the system. The behavioral level represents management and production processes carried out by the system. The processes can interact with the data level to extract, generate, and store data. The communication level relates to the network used to exchange data and activate processes between geographically distant users or machines.

Systems Requirements

A critical factor in successful requirements analysis appears to be the understanding not only of what the system under consideration should do, but also why. To capture the purpose of an information system, one needs a mechanism to describe the behaviour of the organization in which the system will operate. This approach suggests further understanding and modelling of the organizational goals and the way that these goals become operationalised. In software systems development we often make the distinction between the enter prise world and the system world. The former describes the domain about which the proposed software system is to provide some service, while the second is concerned with specifications on what the system does and include descriptions of the systems requirements, conceptual designs and implementations. This paper describes an approach which involves the explicit modelling of organizational objectives, social roles and operations and the synthesis of these different perspectives towards a set of information systems requirements.

An information system that works in one application and environment may not work in another. Successful adoption of information systems requires that the organization evaluate candidates to ensure that they satisfy intended goals and consider the backgrounds and capabilities of the users. This paper describes an approach for evaluating and implementing information systems that satisfy technical requirements and organizational goals. Integral to this approach is the use of an assessment instrument consisting of objective-driven rubrics that are redundant to ensure consistency. This approach is applied in an NSF-supported CI-TEAM project to evaluate candidate systems to support an online cyber-collaboratory to enhance product dissection and reverse engineering activities in the classroom and to suggest improvements for the next generation system.

Information has become an essential resource for the survival and sustainable development of modern organizations, which face the constraints of their unstable and continuously changing economic and technological environments. In order to manage effectively this valuable resource, organizations need information systems that play a critical role in information management and in supporting complex organizational processes. In particular, to support innovation processes and short time-to-market constraints organizations’ information systems must be agile and flexible. The information systems’ urbanization may be considered as one of the main solutions proposed by researchers since the late 1990s to help organizations build agile information systems. Nevertheless, despite the advantages of this concept, it remains too descriptive and presents many weaknesses. For example, there is no useful approach dedicated to urbanized information systems construction. In this chapter, the authors propose a development approach of software solutions that are compliant with the information system urbanization rules characterized by their main dimensions.

Financial information system is an information system that provides information to individuals or groups of people, both inside and outside the company that contains financial problems and information about the flow of money for users in the company. Financial information systems are used to solve financial problems in a company, by meeting three financial principles: fast, safe, and inexpensive.Quick principle, the intention is that financial information systems must be able to provide the required data on time and can meet the needs. The Safe Principle means that the financial information system must be prepared with consideration of internal controls so that company assets are maintained. The Principle of Inexpensive, the intention is that the cost of implementing a financial information system must be reduced so that it is relatively inexpensive.Therefore we need technology media that can solve financial problems, and produce financial information to related parties quickly, safely and cheaply. One example of developing information technology today is computer technology and internet. Starting from financial problems and technological advances, the authors make a website-based financial management application to facilitate the parties that perform financial management and supervision.Method of development application program is used Waterfall method, with the following stages: Software Requirement Analysis, Software Design, Program Code Making, Testing, Support, Maintenance.

The distinctive quality of the new social structure is that information becomes the only factor of production. In today's organizations, public administrators are directly responsible for applying information to administrative processes. In addition to his managerial responsibilities, a knowledge based organization requires every employee to take responsibility for achieving efficiency. This has increased the importance of information systems in the decision-making process. Information systems consist of computer and communication technology, data base management and model management and include activity processing system, management information system, decision support systems, senior management information system, expert systems and office automation systems. Information systems in the health sector aim at the management and provision of preventive and curative health services. The use of information systems in healthcare has the benefits of increasing service quality, shortening treatment processes, maximizing efficiency of the time, labour and medical devices. The use of information systems for clinical decision making and reducing medical errors in the healthcare industry dates back to the 1960s. Clinical information systems involve processing, storing and re-accessing information that supports patient care in a hospital. Clinical information systems are systems that are directly or indirectly related to patient care. These systems include electronic health/patient records, clinical decision support systems, nurse information systems, patient tracking systems, tele-medicine, case mix and smart card applications. Diagnosis-treatment systems are information-based systems used in the diagnosis and treatment of diseases. It consists of laboratory information systems, picture archiving and communication system, pharmacy information system, radiology information system, nuclear medicine information system. This study aims to evaluate the effectiveness of health information system applications in Turkey. The first part of the study focuses on the concept of information systems and the types of information systems in organization structures. In the second part, clinical information systems and applications for diagnosis-treatment systems in Turkey are examined. Finally, the study evaluates applications in the health sector qualitatively from the new organizational structure, which is formed by information systems.
