Can somebody help me with the Use Case Diagram . I am confused
of what I am suppose to do.
Here are the instructions :
Your team should produce a Use Case Diagram and the associated
Use Case Descriptions/Narratives for all the use cases in the
diagram. The resulting document should havethe professional look
and produced by a word processor, graphics/presentation/drawing
software, and/or a CASE tool (e.g., Microsoft Word, Microsoft
PowerPoint, ArgoUML, Dia, Visual Paradigm, Visio, etc.). All
project documentation must be handed-in no project assignment
will be accepted via email.
Your team is the expert in object-oriented requirements,
analysis, software design, and software development. It is your
teams job to build a system that will satisfy the minimum
requirements specified in Section III below. The bottom line
build a system to help a local college library to automate and to
improve their manual processes as much as possible. Remember the
requirements are incomplete so be creative and use your imagination
to build a complete Use Case Model.
REQUIREMENTS
A private liberal arts college library in the northeastern
United States needs a new Library Information and Administration
System (LIAS) to track and manage its resources. They wanted a
computerized system to replace the current manual processes. The
most obvious resource the library must manage is its books. Books
are checked out, checked in, and requested by library patrons.
Books can also have special status if they are placed on reserve or
if they are reference books. In either case, such books may not
leave the premises. Reminders are mailed to patrons when resources
are more than two weeks overdue. Patrons are fined $0.25 per day
that books are overdue. Students cannot obtain their diplomas if
they have overdue charges that do not clear from the library.
The library also has other resources that may be checked out,
including music CDs, software, audio tapes, and videos (VHS tapes
and DVDs/BDs), each of which may only be checked out for one week
at a time.
There are two types of patrons in this college library:
faculty/staff and student. A student works for a library does not
classify as a staff. Faculty/staff may check out books for three
months, and student may check them out for 2 weeks. Any checkable
library resource may be renewed as long as no other patron has
requested it. Notice will be sent out when the resource is
available to the patrons who put a hold on the resource. A
requested resource will be held for two weeks for a patron. If it
has not been checked out within two weeks, the resource will be
returned to general circulation.
Faculty may place a book on reserve for the period of one
semester, or they may bring in foreign resources (books, papers,
disks, music CDs, magazines, video tapes, DVDs/BDs, or audio tapes
that do not belong to the library) and put them on reserve.
The library must also manage a large selection of weekly,
monthly, and quarterly magazines and journals, which may not be
checked out but are available as reference materials. These
magazines and journals are annually bound into volumes as reference
books. Additional activities of the library staff include
re-shelving books, renewing magazine/journal subscriptions, and
ordering new library resources.
In automating the manual processes, LIAS should allow patrons to
browse all the library resources on-line (users should be able to
search on-line catalog by author, subject, keyword, resource title,
or Dewey call number). Patrons should be able to renew check-out
items on-line. LIAS must also connect to the holdings of a nearby
local public library so that interlibrary loan requests can be
fulfilled.
Several library staffs are classified as LIAS administrators.
LIAS administrator maintains user information. His/her
responsibility includes the acquisition and retirement of books in
the library collection. In acquiring new books, a balance between
meeting the requests of patrons and achieving a representative
breadth in the collection is sought. Books are retired when their
content is deemed to be out of date and of no historical value.
Ideally, when a book is out of date, it will not be retired until a
more up-to-date resource has replaced it in the librarys
collection.
LIAS should authenticate and distinguish the functionalities for
two groups of user: library patrons (faculty/staff and student) and
LIAS administrators.
LIAS will be able to generate some useful reports. Only the
administrators can generate and access these reports. Examples of
useful reports include expiration dates of magazine/journal
subscriptions, number of books in each category (e.g., history,
computer science, and so on), book usage (so that additional copy
of the same book maybe needed), library statistics (patrons,
newspapers, magazines, journals, books, or any other library
resources), etc.
I will rate thump up for you once you post the solutions.
