摘要：Large amounts of resources have been and continue to be invested in information technology (IT). Much of this investment is made on the basis of faith that returns will occur. This study presents the results of an empirical test of the performance effects of IT investment in the manufacturing sector. Six years of historical data on IT investment and performance were collected for 33 valve manufacturing firms from the CEO, the controller and the production manager in each firm. Investment was p...

摘要：This study compares a linear keyword language interface and a restricted natural language interface for data retrieval by a novice user. The comparison focuses on the effect of different data base interfaces on user performance (as measured by query correctness and query writing time) in a query writing task across varying query types and training levels. To accomplish this objective, a laboratory experiment was conducted using a split-plot factorial design using two between-subjects factors a...

摘要：Is-a relationships are widely recognized as conveying important information for database design. Although these relationships are implicitly hierarchical in nature, it is not uncommon to find collections of is-a relationships that form nonhierarchical structures. This paper formally defines structures and classifies and interprets them. It illustrates how is-a structures can be used to identify possible database design errors or inefficiencies and to produce a database design that incorporates...

摘要：This paper defines an information system design theory (ISDT) to be a prescriptive theory which integrates normative and descriptive theories into design paths intended to produce more effective information systems. The nature of ISDTs is articulated using Dubin's concept of theory building and Simon's idea of a science of the artificial. An example of an ISDT is presented in the context of Executive Information Systems (EIS). Despite the increasing awareness of the potential of EIS for enhanc...

摘要：The information systems (IS) development activity in large organizations is a source of increasing cost and concern to management. IS development projects are often over-budget, late, costly to maintain, and not done to the satisfaction of the requesting user. These problems exist, in part, due to the organization of the IS development process, where information systems development is typically assigned by the user (principal) to a systems developer (agent). These two parties do not have perfe...

摘要：Personnel Is one of the most important resources for the performance of Information Systems (IS) and Information Center (IC) organizations. The scarcity of new employees, the difficulty of training and a high turnover make personnel management in these areas a difficult problem. For IS employees, the relationships between job satisfaction, organizational commitment and intention to leave the organization have been established. Because the size of the investment and the number of organizations ...
