Question

Instruction:

Create a UML essential use case model for a new library management system. Use a UML s/w tool to do the work (i.e. MS Visio or LucidChart). A narrative description of the use cases in your model (select one or two for practice) is also required. A narrative template is supplied in this document. To complete the use case narrative, you may make assumptions or create data points as needed.

A use case is a depiction of a to be systems behavior or functionality under various conditions as the system responds to requests from users.

In creating a use case model, first identify the actors, then the system’s response(s), while connecting the actors to the responses with a line segment. There is no requirement to time order the use cases.

Begin at a high level. Once you have a model that represents the major actors and behaviors of the system, you may want to consider creating a more detailed model of one or more of the use cases if there is a development need. In this way you do not clutter the “big picture” yet can show detail if required.  

The use cases in the model should be coherent. This means that they are connected and related to one another achieving an overall purpose. See the next slide as an example.

The basic components of the use case model include actors, use cases, boundary line (optional), line segments. There are more advanced features that we will be studying next.

Library Management System Requirements:

A university is retiring its old library management system and planning to develop a new system. Your team is asked to understand the requirements for the new system and develop a use case model.

• Librarians use the system to update the inventory of items available in the library. Items may include books, magazines, and journals. When a new item needs to be ordered, library personnel can use the system to place the order and the system will send the order to the publisher. Publishers have their own order management system that is capable of electronically receiving orders from the university’s library management system. When the ordered items arrive from the publisher at the library, the librarians have to update their inventory with the new items that have been added to the collection.
• Librarians use the system to allow patrons, who are either students, alumni or faculty members, to loan items. Items can be loaned for up to 30 days at a time. Before an item can be loaned the patron needs to have an account in the system. Patrons can renew their loans or reserve items currently on loan to some other patron using this system through the Internet.
