 calculator Supplementary Specification

1.            Objectives

The purpose of this document is to define requirements of calculator.  This Supplementary Specification lists the requirements that are not readily captured in the use cases of the use-case model. The Supplementary Specifications and the use-case model together capture a complete set of requirements on the system.

2.            Scope

3.            References

None.

4.            Functionality

-        We developed a simple calculator. In this calculator, I achieve a lot of functions. For example, we can choose the operator from the operator box "+、-、*、/".

5.            Usability

The  user-interface shall be Windows 8.1 or Windows Phone 8.1 compliant.

6.            Reliability

Saved tasks should be available every time the user opens the app.

7.            Performance

1. The app can be used at any time the user wants.
2. the operation of it is very simple that you can use it conveniently.

8.            Supportability

None.

9.            Security

None

10.         Design Constraints

The app shall provide a Windows-based desktop interface, a Windows-based phone interface, and a WPF interface.

1.2          Flow of Events

1.2.1       Basic Flow

This use case starts when the user click the ADD button in the “add a task” page.

1. The system checks to see if the due date is a future date. If it is, then the task will be successfully added to the task list. If not, the system will notify the user, and  the task with invalid due date won’t be added to the task list.

1.2.2       Alternative Flows

1.3          Special Requirements

None.

1.4          Pre-Conditions

None.

1.5          Post-Conditions

If the task is added successfully, it will return to the main page with an updated task list. If not, it will stay in the current page.

1.6          Extension Points

None.
