Introduction

Background

Information Systems Definition

An information system (IS) is a set of interrelated elements or components that collect (input), manipulate (process), store, and disseminate (output) data and information and provide a corrective reaction (feedback mechanism) to meet an objective [1].
Information systems generally are classified into five categories: office information systems, transaction processing systems, management information systems, decision support systems, and expert systems. The following sections present each of these information systems.

1. Office Information Systems

An office information system is an information system that uses hardware, software and networks to enhance work-flow and facilitate communications among employees.
2. Transaction Processing Systems

A transaction processing system (TPS) is an information system that captures and processes data generated during an organization’s day-to-day transactions.

3. Management Information Systems

MIS, is an information system that generates accurate, timely, and organized information so managers and other users can make decisions, solve problems, supervise activities, and track progress.
4. Decision Support Systems

A decision support system (DSS) is an information system designed to help users reach a decision when a decision-making situation arises.
5. Expert Systems

An expert system is an information system that captures and stores the knowledge of human experts and then imitates human reasoning and decision-making processes for those who have less expertise.
6. Integrated Information Systems

A system as belonging uniquely to one of the five information system types mentioned above.

Domino’s Sizzles with Pizza Tracker

...the Transaction Processing System (TPS), the Management Information System (MIS), and the Decision Support System (DSS). The Transaction Processing System (TPS) is a computerized system that performs and records the daily routine transactions necessary to conduct business. It is the sales order entry or point of sale (POS) system that captures purchase and payment information. The customer inputs the pizza order that describe the type of pizza crust, the types of pizza toppings, and any side orders. The Transaction Processing System (TPS) then processes the information inputted by the customer and updates Domino’s database with this customer’s pizza order. Next the Management Information System (MIS) helps middle management with administrative activities, controlling, decision- making, and monitoring to see if everything in the process is working well. The Management Information System (MIS) receives transaction data from the Transaction Processing System (TPS) regarding the customer’s order to condense and present this data in reports. Finally the Management Information System (MIS) outputs report information such as type of pizza toppings used, how much time it took to make the pizza, and how long it took to deliver the customer's order. It can provide managers with information like customer demographic data, delivery distances and times, or customer order patterns. The Management Information System (MIS) It can also create reports on the cost of each item on the menu, employee...

Acute myocardial infarction (MI) occurs when localized myocardial ischaemia causes the development of a defined region of necrosis. MI is most often caused by rupture of an atherosclerotic lesion in a coronary artery. This causes the formation of a thrombus that plugs the artery, stopping it from supplying blood to the region of the heart that it supplies. Role of thrombosis in MI Pivotal studies by DeWood and colleagues showed that coronary thrombosis is the critical event resulting in MI. Of patients presenting within 4 h of symptom onset with ECG evidence of transmural MI, coronary angiography showed that 87% had 88 Pathology and therapeutics complete thrombotic occlusion of the infarct-related artery. The incidence of total occlusion fell to 65% 12–24 h after symptom onset due to spontaneous fibrinolysis. Fresh thrombi on top of ruptured plaques have also been demonstrated in the infarctrelated arteries in patients dying of MI. Mechanisms...

The Study of Mis

...responsible for managing, using, transporting and processing information in the organization. MIS is used to effectively solve problems in business on all levels for all areas. MIS can be compared to the study of Computer Science, the study of design, implementation, deployment, and evaluation of computer systems. Although, there are similarities, MIS focuses on the business environment as a way to use computers and similar technology for an organization. MIS has come a very long way through the years. There are six different eras that catalog the evolution. The first era began with the standalone mainframe. Users would use a punch card to type programs. They then would give the punch cards to the MIS personnel to input the information into the mainframe. The second era came about by the introduction of the hard-wired terminal. Users would input programs onto electronic keyboards; MIS personnel would maintain keyboards, known as dumb terminals, and the communication to the mainframe. The PC brought about the third era. Users would bring PCs to work and MIS personnel’s job functions became more complicated as they were asked to help with problems associated with these early PSs. As organizations realized the amount of productivity gain from having PCs, LANS and Enterprise Networks were beginning to be used in the fourth era. LANS WANS and Enterprise Networks complicated the MIS department further as users connected with each other. The fifth era was brought about...

Survey Research Methodology in Management Information Systems: an Assessment

...ABSTRACT Survey research is believed to be well understood and applied by MIS scholars. It has been applied for several years, it is well defined, and it has precise procedures which, when followed closely,yield valid and easily interpretable data. Our assessment of the use of survey research in the MIS field between 1980 and 1990 indicates that this perception is at odds with reality. Our analysis indicates that survey methodology is often misapplied and is plagued by five important weaknesses: (1) single method designs where multiple methods are needed, (2) unsystematic and often inadequate sampling procedures,(3) low response rates, (4) weak linkages between units of analysis and respondents, and (5) over reliance on cross-sectional surveys where longitudinal surveys are really needed. Our assessment also shows thatthe quality of survey research varies considerably among studies of different purposes: explanatory studies are of good quality overall, exploratory and descriptive studies are of moderate to poor quality.This article presents a general framework for classifying and examining survey research and uses this framework to assess, review and critique the usage of survey research conducted in the past decade in the MIS field. In an effort to improve the quality of survey research, this article makes specific recommendations that directly address the major problems highlighted in the review. INTRODUCTION Science may be said to progress on its methods. The production...

Respecting Employees as the Image of God

...Name: Steven Gemma Writing Style Used: Turabian Course and Section Number: THEO 202 – D09 Respecting Employees as the Image of God Most Christians believe that humans were created in the image of God. This belief is foundational to the Christian faith. Being fashioned in God’s image endows even the lowliest of sinners with “intrinsic worth”. Because all humans have intrinsic value, managers have a duty to interact with subordinates and customers in a way that reflects God’s love. All people, including poorly performing workers and unreasonable clients, should be “love[d] because he first loved us” (1 John 4:19 NIV). Many generations of Christians have been taught that humankind was created in the image of God. Scripture describes the creation of man in Genesis 1: 26-28. Most Christians interpret the passage in Genesis 1:27 to mean that humans are created in the physical likeness of God. However, the concept of the image of God goes much deeper than a reference to the simple physical likeness of the Creator. The concept also known as imago Dei includes a purpose of humanity. Specifically, following the creation of humankind, God bestowed upon humanity the charge of flourishing, filling the earth, and exercising dominion over the other creatures. Thus, imago Dei describes humanity’s purpose in life and the sense of self-worth. The concept of imago Dei reappears in Genesis 5. This passage reveals that humankind was created in the image of God and Seth was born in the...

...Evolution of Information Systems (Relevant to AAT Examination Paper 8: Principles of Auditing and Management Information Systems) David Chow FCCA, FCPA, CPA (Practising) This article discusses the evolution of information systems, levels of management decision-making and information systems that enhance the value of information. Students are encouraged to understand the reasons for the development of an information system and its replacement; these will help you identify the benefits and limitations of each type of information system. From EDP to MIS Until the 1960s, the role of most information systems was simple. They were mainly used for electronic data processing (EDP),purposes such as transactions processing, record-keeping and accounting. EDP is often defined as the use of computers in recording, classifying, manipulating, and summarizing data. It is also called transaction processing systems (TPS), automatic data processing, or information processing. Transaction processing systems – these process data resulting from business transactions, update operational databases, and produce business documents. Examples: sales and inventory processing and accounting systems. In the 1960s, another role was added to the use of computers: the processing of data into useful informative reports. The concept of management information systems (MIS) was born. This new role focused on developing business applications that provided managerial end users with predefined management reports that...

...Business Information System A management information system (MIS) provides information that organizations require to manage themselves efficiently and effectively.[1] Management information systems are typically computer systems used for managing. Management information systems are distinct from other information systems in that they are used to analyze and facilitate strategic and operational activities.[2] Academically, the term is commonly used to refer to the study of how individuals, groups, and organizations evaluate, design, implement, manage, and utilize systems to generate information to improve efficiency and effectiveness of decision making, including systems termed decision support systems, expert systems, and executive information systems.ref name=obrien/> Many business schools (or colleges of business administration within universities) have an MIS department, alongside departments of accounting, finance, management, marketing, and may award degrees (at undergrad, masters, and PhD levels) in MIS. Kenneth and Jane Laudon identify five eras of Management Information System evolution corresponding to the five phases in the development of computing technology: 1) mainframe and minicomputer computing, 2) personal computers, 3) client/server networks, 4) enterprise computing, and 5) cloud computing.[3] The first era (mainframe and minicomputer) was ruled by IBM and their mainframe computers; these computers would often take up whole rooms and require teams...

...Preliminary draft: please do not quote or cite  India’s Trilemma: Financial Liberalization, Exchange Rates and Monetary Policy∗ August 22, 2010 Michael M. Hutchison Department of Economics University of California Santa Cruz, CA 95064 USA Rajeswari Sengupta Department of Economics University of California Santa Cruz, CA 95064 USA Nirvikar Singh Department of Economics University of California Santa Cruz, CA 95064 Abstract A key challenge for macroeconomic policy in open economies is how to simultaneously manage exchange rates, interest rates and capital account openness—the trilemma. This paper calculates a trilemma index for India and investigates its evolution over time. We find that financial integration has increased markedly after the mid-2000s, with corresponding limitations on monetary independence and exchange rate stability. This tradeoff has been mitigated, however, with the rise of international reserves as a partially independent instrument of macroeconomic policy. In addition, we confirm that the weighted sum of the three indexes adds up to a constant, validating the notion that a rise in one trilemma variable should be traded-off with a drop of the weighted sum of the other two. Finally, we consider the implications of changes in the trilemma index for macroeconomic outcomes. We find some evidence that greater financial integration and corresponding loss of monetary autonomy and exchange rate stability has influenced inflation and inflation volatility...

Hris Implementation

...Human Resource Information Systems: Implementation in Taiwan Carol Yeh-Yun Lin Abstract Approaching the new century, human resource information systems (HRIS) capitalize on the synergy between the two precious assets, human resources and information technology. This study examines the content and context of HRIS in Taiwan. Research shows that higher HRIS level (DSS>MIS>EDP), usage by top managers, usage by HR staff, and HRIS experience contribute to greater organizational support and HRIS effectiveness. Training, support of the information systems department, involvement of human resource leaders, and computer literacy of HR staff are the most significant contributors to the effectiveness of HRIS. In addition, more emphases on support for decision making, timeliness, comprehensiveness, and accuracy can also enhance systems effectiveness. Introduction In an era striving for excellence, human resources become a crucial source of competitiveness (e.g., Porter, 1985; Ulrich, 1987). Pfeffer(1995) reported that the five best performing firms from 1972 to 1992 in the USA rely not on technology, patents, or strategic position, but on the management of their work force for sustained advantages in the marketplace. The business community also realizes that after people, information is its most important asset (Jenkins and Lloyd, 1985). During the past decade, information technology has greatly impacted the way businesses are managed. Reports on how information...
