Description
The emergence of electronic business promises for companies a sustainable market advantage that comprises an integration and coordination of information flow and product flow between heterogeneous information-system infrastructures. Such information flow that bridges different organizations, includes the linking of business elements into an integrated whole. For such electronic business collaboration (eBC), a loose coupling of those information systems is a requirement as a tight coupling of information systems results in too many agreement details and too much shared context has to be revealed that to the business counterpart.
In eBC, the registration of business transactions is of major legal importance for organizations. A business transaction is a consistent change in the state of a business relationship that is driven by a well-defined business function. Each party in a business transaction holds its own business transaction. For eBC, a transaction concept is important to ensure reliability. To facilitate a loose coupling and highly dynamic establishment of business collaboration, the service oriented computing (SOC) paradigm is increasingly important. Services are self-describing, logical manifestations of physical resources that are grouped as a process, i.e., as a set of actions that an organization is prepared to execute and expose to the web.
With the complexity involved in eBC, no single transaction model is able to meet all requirements. Instead it is necessary to inter-organizationally establish transaction frameworks in a way that does not force companies into disclosing an undesirable amount of business internals. In this seminar a conceptual model of an electronic business transaction (eBT) is explored, based on features that also incorporates business aspects and in which collaborating organizations can safeguard their business internals. Note that an eBT needs to safeguard the legally binding contractual relationships between collaborating parties that dictate responsibilities and the consequences of behavior. The importance of business semantics in an electronic collaboration also has consequences for the nature of the atomicity, consistency, isolation, and durability properties of an eBT.
Pre-requisites
This study seminar is part of MSc studies. Thus, the completion of bachelor-degree studies is required, especially the course for scientific writing.Form of work
In this seminar the working language is English.
- What is the paper about?
- What is the problem under investigation?
- Why is that a problem?
- How is the problem addressed/tackled/solved?
- Why is the proposed remedy a good/better one for the problem?
- Extended abstract (work plan).
The work plan / extended abstract is a refinement of your seminar topic. You may need to interact with the adviser to get the scope and goalsetting of the paper right. The abstracts allow advisers and students to "make a contract" about the content and schedule of the work.
The work plan / extended abstract serves also as the means of making it visible for the rest of the group what kind of talk and paper you will deliver and what your research question and viewpoint are in the discussion. The length of the text is about two pages. The text also includes the title (potentially refined from the original), list of contents, list of main references. The abstracts are published during the second seminar week.
- Seminar paper
The papers will be published at latest one week before the presentation. The length of the paper is about 15-20 pages, counted with font size of 12 pt, and 1.5 line spacing in one column format. The structure and formatting of the paper conforms to the instructions given on the scientific writing course (references, scientific argumentation style etc). The paper is emailed in PDF format to the seminar leaders.
- Seminar presentation
Each session contains one presentation. You may use 60-70 minutes for your presentation, leaving the final 30 minutes for discussion.
- Active participation
into discussions and providing feedback for others.
Before each presentation, you must read the paper and prepare some questions and comments about the topic. You may find additional viewpoints for the topic area using the material related to your own presentation, thus, widening the discussion from the original presentation scope.
At the end of each session, after the discussion, each participant spends a few minutes writing down (anonymously or named) feedback notes for the presenter, both about the paper and the presentation. Practice constructive feedback, and bring out strengths and improvement suggestions. The feedback goes directly to the presenter, who may choose to share or not to share it with the adviser. After others have left, the adviser stays with the presenter for 5-10 minutes analysis discussion.
Active participation is also measured in terms of sessions attended. You can only pass the seminar if you have been present in all but 3 sessions.
The seminar grading takes into account the quality of the paper, success of the presentation and constructive activity in discussions. Main emphasis is on the paper and presentation.
Sessions:
- 22.09.-13.10. Tue 14-16 C221,
- 03.11.-08.12. Tue 14-16 C221
In the following list, we propose the dates and times for presentations according to the list created on the getting-organised session. We have proposed an extra session on first action week: Tue 12-14, for which we confirm my email poll.
We also have two persons who have been indicated to participate the seminar, but who do not yet appear on the schedule. We will poll the suitable dates and times for those presentations as well, as soon as the topics have been agreed on and the persons have confirmed their participation.
