UML Modeling for a Simple Software System

Your task for this assignment is to develop a set of commonly used UML models for the software system described below.

Customers description of desired software:

Customer asked you to develop a parent control software E-Guard that monitors, blocks and controls internet usage in real time. The E-Guard is a standalone software that can be run in MS Windows, Linux and Mac operating system with the following functions/features.

The E-Guard shall allow parents to check web activity, keystroke, chat, email, IM and launched application.

The E-Guard shall keep a local DB of unhealthy websites and synchronize the DB with the remote server in a daily basis. (note: Remote server is maintained by a 3^rd party service vendor who publishes and updates unhealthy websites. It is their responsibility to create and maintain the remote server. Your job is to copy its DB to your local drive in a daily basis)

The E-Guard shall block unhealthy websites

The E-Guard shall remove unhealthy words from search engine (note: it is 3^rd partys responsibility to create and maintain common unhealthy keywords)

Once a suspicious activity is identified, the E-Guard shall take snapshoot of the screen and notify parents by email and text message. The suspicious activities include trying to browse unhealthy websites, nasty words appear in email/chat/IM or typing blocked keywords in search engine.

The E-Guard shall allow parents to configure the setting. The setting includes, blacklist, whitelist, blocked keyword, internet time control, categories to be blocked (it is 3^rd parths responsibility to create and maintain the website categories), etc

Only authorized users have access to the configuration and uninstall.

UML Modeling: UML diagrams that are (minimally) needed include:

Use cases

Use cases and their use case scenario specifications

Use case diagram(s)

Class diagram (analysis level)

Include attributes and basic (and other) methods for each class

You may choose either C++, Java, or C# notations, if necessary

Sequence diagrams

These should be for any two non-trivial use case scenarios

State diagram(s)

Choose any three classes and draw state diagram for each

Activity diagram(s)

Must apply swimlane in the diagrams and should be at least three diagrams

Deployment diagram

Requirements model

Formal requirements model

Non-functional requirements model
