摘要：Executive information systems (EISs) are challenging applications to develop, and many organizations are unsuccessful in their efforts, A major problem is determining the information requirements for the system. A multi-stage study was conducted to explore (1) methods used to determine the information requirements for the initial and ongoing versions of an EIS; (2) how frequently the methods are used; (3) how useful the methods are; and (4) in what situations the methods are useful or not usef...

摘要：Lack of familiarity with database design methods could prevent many end users from effectively implementing their database management system packages. An inexpensive solution would be for end users to learn required database design skills from software tutors tailored to their needs. This research describes two tutors developed to teach these skills to end users. The tutors were based on a modified Entity-Relationship database design method. They improved an end user's natural learning process...

摘要：User-led development is gaining popularity with organizations wishing to increase user involvement and control. Typically in this approach a small group of users is given the responsibility for managIng the project and representing the user community in determining requirements, testing, training, and system implementation. This paper explores the end user's perception of the quality of his or her representation and satisfaction with the application system within an organization employing user...

摘要：A common classification of data models is based on their abstraction levels: physical, logical and conceptual. The user-database interaction can be similarly classified. For the conceptual-level interaction, the user and the database exchange information on the user's world, e.g., information of entities, relationships, and attributes. For the logical-level interaction, the user and the database communicate based on concepts in the database system, e.g., relations and join operations. We expec...

摘要：Database design is often described as an intuitive, even artistic, process. Many researchers, however, are currently working on applying techniques from artificial intelligence to provide effective automated assistance for this task. This article presents a summary of the current state of the art for the benefit of future researchers and users of this technology. Thirteen examples of knowledge-based tools for database design are briefly described and then compared in terms of the source, conte...

摘要：Distributed group support systems are likely to be widely used in the future as a means for dispersed groups of people to work together through computer networks. They combine the characteristics of computer-mediated communication systems with the specialized tools and processes developed in the context of group decision support systems, to provide communications, a group memory, and tools and structures to coordinate the group process and analyze data. These tools and structures can take a wi...

摘要：Cognitive feedback in group decision making is information that provides decision makers with a better understanding of their own decision processes and that of the other group members. It appears to be an effective aid in group decision making. Although it has been suggested as a potential feature of group decision support systems (GDSS), little research has examined its use and impact. This article investigates the effect of computer generated cognitive feedback in computer-supported group d...
