1. Introduction
1.1. Purpose
This document will cover the following information:
-
Brief description of the project (project overview, business goals, general
constrains about technical and business problems).
-
Architectural drivers (functional requirements, quality attributes and
constraints).
-
Architectural design (C&C View type, Module View type, Allocation View
type).
This document is intended for the following audience:
-
Stakeholders (direct or indirect) of the KFC Vietnam Order System project.
-
Audience that might want to get an insight into or analyze the architecture
and design of KFC Vietnam Order System project.
2. Project Overview
2.1. Business needs
KFC are known to at Vietnam with a name calling the chicken run Kentucky chain stores served of dishes from chicken, Bo-GO and Mon Floating known first is
a chicken bee run Kentucky is invented by Harland Sanders.
Six one series successfully of the system chain food restaurants Trademark
quick with KFC (above 10,000 restaurant has been a development in the entire
World), Vietnam at KFC have joined to the field once the first to 12/1997 at Saigon
Trade Center Super Bowl. Time here, the system food restaurants quick is already
lost in most of the route City the Philippines.
Nowadays, KFC Vietnam stores has many branches in many provinces and
cities. They, therefore, need a tool help their customers easily to search and order
food. Besides that, this tool also support KFC Vietnam stores manager their

customer easy and convenient. Especially, this tool must be effective to compete
against other company in the same business area like Lotteria or McDonalds.
2.2. Business drivers
Base on the business needs our team decides to make a KFC Vietnam Order
System. This system will be developed by PC and Laptop and available tools for all
Android Devices.
2.3. Project goal
The purpose of the project is to deliver the KFC Vietnam Order System
satisfying the client’s requirements:
-
Customers can search, order, and add to their favorite, and so on (refer to the
proposed solution).
-
Administrator of the system can manage system such as add foods and users,
edit user’s information, and so on (refer to the proposed solution).

4. C&C view
We mainly used C&C view to argue and reason about architectural properties,
quality attribute requirements, and functional requirements that the system must adhere
to.
This view type partitions the system into components that have some runtime
presence such as processes, objects, data stores and connectors or that represent
pathways of communication such as information flows, and access to shared storage.
The diagram below shows the architecture overview including the Feedback Teachers
Website components and other related components. We have representations and
behaviors for important components in the following sections.

Client is a component which manages all of user
inputs, and raises appropriate events: view dishes;
add/remove dishes to favorite list, add/remove dishes to
cart, check out but all action is not directed to database,
its operation via Web Service.
Server
Server is a component which is manages all users,
dishes, orders information. The major different between
client is read and modify direct to database.
Database SQL
Database is a component which contains information
of dishes, users, and all orders information. All data of
system needs.

RESTful is method to call and return information from
Web Service.

Query is command for interacting with database.

5. Module view
This view type partitions the system into a unique non-overlapping set of
hierarchically decomposable implementation units (modules). The goal is to show how
the source code is decomposed, as well as the dependencies between modules. In other
words, it shows the decomposition and the “uses” relation.
The elements in this view type are UML packages or UML classes or interfaces.
Packages are hierarchically decomposable; hence, placement of a class or package inside
another package in a diagram implicitly indicates an is-part-of relation. This view type
also shows dependencies among implementation units. It tells developers what other
modules must exist in order for their portion of the system to work correctly.
This view type was selected because it helps the following roles:
-
The project manager, who must define work assignments, form teams, and
formulate project plans and schedule, knowing which modules are more critical
in terms of dependencies.
-
Testers who use the modules as their unit of work to create test cases and
perform the tests.
-
The configuration manager who is in charge of maintaining current and past
versions of the units in consistent and functional package assemblies, being able
to produce a running version of the system.
-
Developers, who are required to implement the elements.
-
Maintainers, who are tasked with modifying the software elements.
-
The software architect, who defines the software elements that are sufficiently
large or complex enough to belong at the architectural level. The architect can
