Agenda
1. Database system in question
2. VBScript in a few words
3. How the 3-Tier Architecture fits in
4. Differences between VBScript and Jscript
   (Pros and Cons)
5. Conclusion (Should VBScript be used?)
Student Database
• UCL PORTICO
• provider of Integrated Provider Management
  (IPM) solutions for payers, which is based on
  VB Script and is used for companies, hospitals,
  libraries, Universities or other organizations
• (UCL) uses it for students and staff to share
  information, selecting optional courses, linking
  to other sources, and doing applications.
What makes PORTICO convenient?
• Another advantage of Portico is, it can be accessed
  from several client-side servers. In other words, it runs
  different versions, such as administration version,
  students’ version and teachers’ version.
• In the case of selecting optional courses,
  administration can log in Portico to see how many
  students have chosen a particular course and manage
  it. If there are too many students in one course, the
  administrator can suggest students to change their
  options or extend the classes.
VBScript
3-Tier Architecture
• Type of design used to create systems
• Improved from 2-Tier Architecture
• More effective in handling a larger number of
  users
3-Tier Architecture
• More scalable than the other solutions – can
  include as many clients as desired
• An application server can be used to cache
  persistent data to increase performance and
  stability.
3-Tier Architecture
• + security is the best compared to the others
• A single physical middle-tier can be shared by
  a number of clients. Thus, the scope for reuse
  and maintenance is heightened

Should vb script be integrated into ucl portico

Editor's Notes

  • #7: Runs the traditional client-server model, but from a web server. The client merely displays the GUI (Graphical User Interface) and data, but it plays no part in producing results.
  • #8: As mentioned earlier, the 3TA is a design used in the creation of systems. Vbscript can be used in 2 of the 3 architecture layers – business logic application layer (sometimes also pulls out data from the database layer to produce information in the presentation layer) and the presentation layer. Also, in reference to the student record database, vbscript can be used to create some common features found in that record.
