Business Information Systems (BIS) is a professional discipline that combines Computer Science, Management, and Business Administration. In this article the researchers evaluate the evolution of BIS curriculum in terms of its past, present and future, considering its historical background, the existing strengths and weaknesses, and how it can be developed to meet market needs. The study reveals the skills required by a BIS graduate and highlights how the existing/existed BIS curricula have made their graduates weaker when compared with Computer Science and Business Administration specialists. The research further compares the existential crisis of BIS with Library and Information Science (LIS) discipline, which have also faced a similar controversial crisis concerning their disciplinary boundaries, whether it belong to Social and Behavioral Sciences or Computer Science and Engineering and yet succeeded in its growth and contributions. This research concludes that the BIS curriculum is still budding and needs to be re-evaluated and updated regularly to meet the changing demands of the market highlighting the need for collaboration between academia and industry to ensure that BIS graduates are equipped with the skills that employers require. The paper finally proposes a balanced model of BIS curriculum that incorporates the latest technology updates. The proposed curriculum model aims to address the current gaps in BIS education and meets the changing demands of the market. [ABSTRACT FROM AUTHOR]

E-commerce business process nets (EBPNs) are a novel formal model for describing and validating e-commerce systems including interactive parties such as shopper, merchant, and third-party payment platform. Data errors and nondeterminacy of the data states during the trading process can be depicted with the help of EBPNs. However, the problem about how to analyze EBPNs remains largely open. To analyze their data-liveness, data-boundedness, and reachability, this paper presents two analysis methods. For EBPNs, reachability analysis is proposed based on a 3-D incidence matrix method. Additionally, reduction methods are proposed for a special EBPN. Finally, the validity and reliability of the proposed methods are illustrated via the examples of e-commerce systems.

van der Aalst et al. proved that the soundness problem is solvable in polynomial time for free-choice workflow nets (FCWF-nets). However, FCWF-nets cannot model most web services composition and interorganizational business processes because the interaction among processes does not usually satisfy the free-choice requirement. Asymmetric-choice workflow nets (ACWF-nets) as a larger class than FCWF-nets can model lots of such cases. Our previous work showed that the (weak) soundness problem is co-NP-hard for three-bounded ACWF-nets. Later, Tiplea et al. proved that for three-bounded acyclic ACWF-nets, the weak soundness problem is co-NP-complete. We sharp these results in this paper. First, we prove that for ACWF-nets, whether they are one-bounded or k -bounded ( k~\boldsymbol > 1 ), the soundness problem is co-NP-hard. Second, it is proven that the soundness is equivalent to the weak soundness for any acyclic ACWF-nets, i.e., an acyclic ACWF-net is sound if and only if it is weakly sound. [ABSTRACT FROM AUTHOR]

Database technology affects many disciplines beyond computer science and business. This paper describes two animations developed with images and color that visually and dynamically introduce fundamental relational database concepts and querying to students of many majors. The goal is for educators in diverse academic disciplines to incorporate the animations in their existing courses in order to meet their pedagogical needs. The introduction of the animations was assessed and evaluated within several contexts, including non-majors courses offered by computer scientists as well as a course on computational molecular biology. The evaluation indicated that student knowledge of fundamental database concepts improved significantly with the use of the courseware. The animations provide visual learners with an engaging method to learn the topics presented with the ability to replay the dynamic presentation. Overall, the evaluation indicates the accessibility of database topics across the disciplines as well as the specific concepts that need further elaboration. [ABSTRACT FROM AUTHOR]
