I. System Objective & Guidelines The 3-tier architecture will be applied in developing the resort

management system on this coursework.

The 3 tiers are as

follows: the Data Tier (the

Data Server), Logic Tier (the

RM.DataService which

include my use of WCF Data

Service) and the Presentation

Tier (RM.Client which include

my use of MVC3).

All the local system functionalities are also

operated using the web services.

I have used the WCF Data service technology

to design the Service Tier. This technique provides a

more efficient way to get data from Database Server.

This is called the Entity Framework which is defined

within the Service Tier. Data Service Tier defines web

services used to call these methods within the Entity

Framework. Those services are then uploaded to the

internet in order to be used

I have used the MVC3 technology to develop the

Presentation Tier. This tier access the data by using

the provided web services from the Data Service Tier.


4

I also have used one supported software call “Developer Express”

which helps me in generating a proper view of user interface as well as better

creating the report.

It is because that the library of the Developer Express software is quite

big referenced to my project, so that I did not attached them to the project

package when upload my coursework. It is required that the client will download

this software and follow my instruction to successfully run the system.

I have used the trial version of this supported software which is illegal.

The Client is also expected to download the trial version.

Tips for setting up the DevExpress Library.

This is where we can have a free trial version of the Developer Express

Software. https://www.devexpress.com/

Step 1: download and install the software choosing the trial version

- If the installation is succeeded, we can see it as follow

Step 2: follow the photos as your instructions:

Choose DEVEXPRESS – Project Converter – Project Converter…

https://www.devexpress.com/


5

Choose Browse to navigate to the package need to add the software library


6

We have two packages which need to add the addition library, pick any of it

to process the next state. You are required to do the process again to pick the other.

I choose the

RM.Local first. Then you

click “Upgrade”


7

When it finish importing the DevExpress Library, click “Finish” and you are

all done. The final step is to run the project.

Remember to repeat the whole process with another package name

RM.National as I have mentioned above. We need the two package with supported

library to run.

II. Introduction

The coursework has placed a situation wherein the developer is required to

build a resort management distributed system. As stated in the case study that this

company has three resorts in various places. The main purpose of distributed

system here is that National resort, hosted by one of these three resorts will be able

to run the other reports by connecting to each of the local resort’s provided service.

There are also requirements to each of the local resort in the purpose of managing.

The system consists of three kind of staff: Sales Staff, Local Manager and

National Manager. Each of them own the right to be able to run a series of system

functions. That means there are some functions that are required the higher staff

role. The work is as follow:

- Sales staff, local manager, national manager

o Manage the sales of room (booking, payment)

o Manage the sales of food/ beverage (booking, payment)

- Local manager, national manager

o Produce weekly/ monthly local report of room occupancy

o Produce weekly/ monthly local report of the staff sales statistics

o Produce weekly/ monthly local report of the food/ beverage and room

sales.

- National manager

o Produce weekly/ monthly national report of room occupancy

o Produce weekly/ monthly national report of the staff sales statistics

o Produce weekly/ monthly national report of the food/ beverage and

room


9

III. Assumption The sales staff is only able to access several fields as follows:

o Food/ Beverage and Room invoice management (create, edit invoice)

o Food/ Beverage and Room payment management (edit payment)

o Food/ Beverage and Room management (create, edit item)

o Customer Management (create, edit customer)

Local Manager does not have the right in Staff Management due to the

developer rule and policy. They have the same access like the sales staff

and plus one more right is that to access the local report field.

The National Manager get all the rights in any resort. They have one unique

account in each resort with the highest priority.

- There might include multiple items within an individual invoice. Each item

is a complete process of creating, so that user is expected to choose just one

Staff Code during the process of generate a complete invoice.

- Those payments with their status of “Waiting” can be edited to “Paid”

6. Deployment Diagram

The illustration for the 3 tier-architecture

of the current developing system

Data Tier: or called database server, contains the external data source. As in

here we use the Microsoft SQL Server.

Logical Tier: contains two inner sub layers: the Data Access Layer and the

Service Layer.

- We use the technology of WCF Data Service which include the entity

framework as place to state all accessing method to the Data Tier. The

Data Access Tier is used to store the entity framework library as well

as the data from database server.


49

- The Service layer defines services that retrieve data from the data

access tier in order to avoid connection from the Presentation Layer to

the Data Access Layer.

Presentation Tier: define the connection to the public services from the

Logical Tier.

6. Invoice Management

Invoice management is the most important feature of the whole resort

system. As in here, we provide a proper way to maintain and monitor the

Food/Beverage and Room invoice.

Food/Beverage Invoice

Main active screen


69

Each invoice of this kind can contain from one to many kind of foods and

beverages.

Each food/beverage invoice is associated with only 1 customer and 1 staff

To create a new food/beverage invoice, first to select the customer

If the customer has used the resort service before, there will be customer’s

detail information stored on the system. User only need to select customer name as

the owner of the invoice. Otherwise, user clicks on “Create” located under the

Customer box to store a new one.

Secondly, user click on “New” to start ordering the food and beverage.

There is a rule as mentioned above that, each invoice contains one or many items

but is only belonged to 1 customer and 1 staff who place it.

Each item is followed with its own

price which is automatically shown up when

user browse for a specific food/ beverage.


70

After that, user adjusts the item quantity incase the customer wants more

than just one for each item. System will immediately perform the total of this item

as shown below.

User then selects his/her staff code as the one who is in charge of the

current invoice.

Then user click on “Update” to temporary finish ordering an specific item of

the invoice.


71

Normally, the customer will order more than an item one time, and that

means user is expected to repeat the process again to add one or more items to the

current invoice.

By click on the “New”

located at the beginning of

each item row, user can

achieve the purpose. User can

also choose “Edit” to adjust

the quantity of the item, or

simply choose “Delete” to

remove the chosen item out of

the current invoice.

The picture on the left

shown that, the current food/

beverage invoice has 5 items.

It is belongs to a customer

name “Todd Nguyen” and the

staff who is in charge of

placing it has the code “S005”

Finally, user inputs the

information of “Payment

Method”, “Payment Date” and

“Invoice Status” to export the

current invoice.

Payment Method can be

Cash, Credit Card or whatever

the user define to get benefit.

There are two status: “Paid”

means customer done with

solving the invoice, and


72

“Waiting” means customer not

yet pay for the invoice.

Room Invoice

It is quite the same of Room Invoice to the one of Food/ Beverage. User then

needs to adjust the time that customer need to use the room service. The “NoD”

indicates the number of days from the time customer move in to the time move out

Once User click on “Create” the invoice (Food/ Beverage or Room) will be

exported into “Payment” section.


73

Those invoices which are already Paid cannot be modified, the remains

waiting invoices can be changed with information about Date, Payment Method

and Status.

7. Report Management

There are 4 kinds of report that we design for the system to perform.

The report of Room Occupancy

User needs to adjust the time period wherein the Rooms which are in service

within will be performed. There is the information about a number of day a

specific room is rented.


74

User base on the total number of item displayed on the report to calculate the

occupancy rate by dividing it to the total number of owned room and multiply with

100%. The process of calculating will be made manually as we did not provide to

the system.

The Report of Food/ Beverage Sales

User adjusts the time period for the system to perform which food and

beverage within this time.

The report show the total number of quantity of each food and beverages

that has been sold out during the expected time period. There is also the total

amount of each item and the final total of all item belong to the adjusted time.

The Report of Room Sales

User adjusts the time period for the system to perform which room within the

the time

The report shows the price of each room per day, the total amount of money

for each room and the final total of all room listed in the report


75

The report of Staff Sales

User adjusts the time period for the system to perform which staff within the

the time.

The report shows the total amount of money an individual staff has made

during the specified time period. There is also the final total of all staff during this

time.

NOTICE: We develop a distributed system with multi resort located in

different areas. In order to illustrate for the term of distributed system, there are

two main kind of the report process, the “National report” and “Local Report”. As

said in the Case Study, there is one that stands for a national resort wherein the

national manager can access into other resorts system and generate the list of all

report.

The National manager can access to any resort system belongs to that resort

brand. So that they can easily manage the information of customer, staff, food and

room as well as the sales statistic. Base on the national resort system, national

manager does not have to login into other system to get report. It is the primary

function that allow the manager to get those report right at one place and one time

conveniently.

VI. Student Conclusion

1. System functionalities:

The system has covered enough required fields for all user: Sales

Staff, Local Manager and National Manager. However, it still

contains some logic mistake when running these system function as if

user does not follow the right path, it can throw out a new error which

I have not figured out yet.

2. Security:

The authentication of the system is pretty good as it does not allow

any staff with inappropriate role to access and use the important

system features. Only one staff with highest right (national Manager)

can access onto those features and run them to collect data.

3. Performance:

The system performance is rather slow. Personally, the access through

the web service takes more time than the direct connection between

presentation layer and business layer. However, the use of web service

is safer.

4. Scalability

The attributes of each object developed on the system is quite wide

and that there is almost unnecessary when adding more new resources

that required the change in system architecture.

5. Transparency

All the Staff will not know where the service come from.

6. Failure

The chance of failure to this system is rather low. I have caught

almost all the error which can be thrown out.
