You are asked to design a software package for an On-line Banking System (OBS). The OBS will take requests from its user on the

Internet. The requests include:
 Open an account with savings, checking, and CDs.
 Transfers between savings and checking, and Establish a CD are also among the requests.
 Close an account, or just close the savings account, withdraw CD are also permissible.
 Deposit, withdraw from a checking account are as routine requests

Step1. Identify the actors and the software entities for the system to be implemented.Step2. Describe five Customer/Business Use Cases.Step 3. Derive User Interface from the Business Use Cases. Draw a few user interface sketches.Step 4. Draw a Use Case Diagram, which consists of five use cases, defined in Step 2. (use Visual_Paradigm software)Step 5. Create at least 7 to 9 Classes from Actors and Entities as you have defined in the use cases. (use Visual_Paradigm software)Step 6. Write attributes and Operations (Methods) for each Class. The Operations are derived from Activities in the system. (use Visual_Paradigm software)Step 7. Draw one Sequence Diagram with 5 to 7 entities as you defined in use cases. This is the Behavior Modeling. (use Visual_Paradigm software) Draw communication diagrams for the Use cases you defined in Step 2 and 4. This step is called Use Case Realization. (use Visual_Paradigm software)Step 8. Now you are at System Design Stage to make technology, and topology choices. That is to be done in the rest of this semester.The last step: Base on the answers for Step 5 and 6, write the Java code for class declaration, variable and method declaration, and Main. If you have time fill in some of the code for methods

Answer:

From the statements described above,The proposed software package Online Banking System(OBS) shall provide the following services to the customer(account holder)

Receive all transaction requests from the customers trough online to perform banking activities

Offer a variety of services in banking like:

Opening an account with facilities of Savings,Checking and CD

Issuing checks and check clearance

Transfer of funds between savings and checking account

Establishing a CD(Certificate of Deposit)

Performing routine activities like

Deposit or withdraw funds from a checking account

Closing an account in one of the following operation

Complete closure of account

Closing only savings account

Withdraw CD (on Maturity of CD deposits) and close CD account

Unlike traditional Banking system, OBS offers all the operations through On-line mode over the internet thereby it eliminates manual intervention for the banking transactions from the Bank's side for most of the transactions except some cases like verification of new account applications or complaint redressal and technical support .In such cases ,There will be some users of the software with special privileges to access certain services to perform activities like user data verification and technical support.

Step:1 Identification of actors and software entities for the system to be implemented

The following are the actors identified in the system

Actors:

The users of the proposed system were classified as:

Customer : A user with an active account

Guest user:The user who applies for an account

Administrator:Maintainsand Controls OBS

Manager: Manages the transactions and Banking related issues

Technical Manager: Resolves technical issues of customers

Software entities:

Bank database :Maintains the data of all user accounts

Application server : Maintains the application software components and hosts the OBS website

Automatic Clearing House system : Processes transactions for checks

Step 2: Designing use cases

Use case diagrams are used to describe the system model by representing a set of use cases .Each use case represents a set of actions performed on the system by an actor.

The following are the two approaches of representing the system in a use case model:

1.Representing a use case for actions done by actors e.g. login , logout,message etc.,

2.Representing a use case for business process(Business use cases) e.g. transfer,registration etc.,

The following is the description of five possible business use cases for the requirements specified above

Birdie Par owns a company that makes golf gloves. She is thinking about introducing a new glove, which would require an addition
melamori03 [73]

Birdie's company will make a profit of $30,000 if she sells 3,000 gloves at the $15 price.

Step-by-step Solution:

Break even point= fixed cost/ selling price - variable cost

here the fixed cost is= $20,000

selling price= $15 and variable cost = $5

BEP= 20,000/ 15-5= 20,000/10= 2000 units

b. if they sell 3000 gloves, the contribution profit will be

total revenue= 3000*$15= $45,000

contribution= selling price- variable cost, 15-5= $10 per unit

the profit is= 3000*$10= $30,000

What is  variable cost?

A variable cost is one that varies in relation to either the volume of production or the number of services provided. There should be no variable costs if no production or services are provided. Variable costs should rise in tandem with increases in production or services.
