You have been requested to develop a Java application for a large company that provides members and the general public an online product catalog for ordering items like books, DVDs, clothes, household products, and
so forth. There are several levels of users, including public (user has not registered), level 1 member, level 2 member, and level 3 member. The level 1 member pays a small monthly subscription fee. Level 2 members are
associated with a small business who pays an annual fee covering less than 100 members. Level 3 members
are employees of large corporations (more than 100 members) who subscribe annually. As the level increases,
so does the discount. The following list highlights these requirements.
The requirements for the application are as follows:
The application will act as an online ordering system.
The company accepts orders online and ships those items to the customer address.
Customers must create a line of credit prior to placing an order.
Customers view products from the catalog of items.
Customers place orders.
The administrator updates account information on behalf of members.
Administrators add, delete, and modify items in the catalog.
The application is able to run under most operating systems, including UNIX and Windows, and has a modern
graphical user interface.
The application is designed for future growth.
Part 1
Review the requirements and, using Visio, develop your design by creating use case diagrams, a class
diagram, and a sequence diagram. Templates can be found in Visio by accessing the UML System template.
There is a use case shape to help you create your use case diagrams. There is a UML sequence shape. Under
“More Shapes,” you will find an entity relationship shape for your class diagram.
Click here to refer to a Visio tutorial to learn Visio basics.
Use case diagrams are used to summarize the relationships between use cases, actors, and systems.
Use Case 1: Create Account
Use Case 2: Place Order
Use Case 3: Add Product to Catalog
Use Case 4: Update Account Information
Sequence diagram that illustrates the various object interactions in their proper sequential order.
Class diagrams depict the objects and information structures used by the application. The definition of a class
is independent of the application itself. Classes describe the objects managed by the application but are
independently defined. Be sure to show relationships between class objects, attributes, data types, and
methods in your diagram.
Class 1: Account
Class 2: Account Level
Class 3: Address
Class 4: Products
Class 5: Order
Class 6: Line Item
Once you have completed your diagrams, copy them into a Word document that will serve as your application
design document. Include explanations for each diagram in your design document.
Part 2
Create pseudocode that describes the necessary flow of your program with respect to both creating a user
account and placing an order. This information should be included in your application design document. This
information should be included in your application design document.
Part 3
Explain your steps regarding taking the business requirements and developing your application design. Provide
details as to the importance of following these important steps prior to coding the application. Describe the
advantages and disadvantages to this process. Discuss how this process relates to the software development
life cycle.
Parts 1, 2, & 3 are all included in the application design document.

Presentation: The worldwide budgetary emergency of 2008-2009 started in July 2007 when lost certainty by speculators in the estimation of securitized contracts in the United States brought about a liquidity emergency that provoked a significant infusion of capital into monetary markets by the United States Federal Reserve, Bank of England and the European Central Bank. In September 2008, the emergency extended, as financial exchanges overall slammed and entered a time of high unpredictability, and a significant number of banks, contract moneylenders and insurance agencies flopped in the next weeks. Extension The emergency in land, banking and credit in the United States had a worldwide achieve, influencing a wide scope of money related and financial exercises and establishments, including the: Generally fixing of credit with money related establishments making both corporate and customer credit more earnestly to get; Money related markets (stock trades and subsidiary markets) that accomplished soak decays; Liquidity issues in value assets and flexible investments; Debasement of the benefits supporting protection contracts and annuity finances prompting worries about the capacity of these instruments to meet future commitments: Expanded open obligation open money because of the arrangement of open assets to the budgetary administrations industry and other influenced enterprises, and the Downgrading of certain monetary forms (Icelandic crown, some Eastern Europe and Latin America monetary forms) and expanded money instability, Foundation In the years paving the way to the emergency, high utilization and low funds rates in the U.S. added to huge measures of remote cash streaming into the U.S. from quickly developing economies in Asia and oil-creating nations. This inflow of assets joined with low U.S. financing costs from 2002-2004 brought about simple credit conditions, which powered both lodging and credit bubbles. Advances of different sorts (e.g., contract, Mastercard, and auto) were anything but difficult to acquire and purchasers accepted an uncommon obligation load. As a component of the lodging and credit blasts, the measure of budgetary understandings called contract upheld securities (MBS), which get their incentive from home loan installments and lodging costs, enormously expanded.

Governments likewise rescued key budgetary foundations, expecting critical extra money related responsibilities. Reason for The Financial Crisis Different causes have been proposed for the emergency, with specialists setting diverse loads upon specific issues. The proximate reason for the emergency was the turn of the lodging cycle in the United States and the related ascent in misconducts on subprime contracts, which forced considerable misfortunes on numerous budgetary organizations and shook financial specialist trust in credit markets. Nonetheless, despite the fact that the subprime fiasco set off the emergency, the improvements in the U.S. contract advertise were just a single part of an a lot bigger and all the more including credit blast whose sway rose above the home loan market to influence numerous different types of credit.

Budgetary organizations have seen their capital drained by misfortunes and compose downs and their monetary records stopped up by complex credit items and other illiquid resources of questionable esteem. Rising credit dangers and extraordinary hazard avoidance have pushed credit spreads to exceptional dimensions, and markets for securitized resources, aside from home loan securities with government ensures, have closed down. Increased fundamental dangers, falling resource esteems, and fixing credit have thusly negatively affected business and purchaser certainty and hastened a sharp moderating in worldwide financial action.

Toward the finish of October a cash emergency created, with financial specialists exchanging immense capital assets into more grounded monetary standards, for example, the yen, the dollar and the Swiss franc, driving numerous emanant economies to look for help from the International Monetary Fund. Eventually, searching for a reason for the momentum money related emergency, it is basic to recollect that associations neglected to complete various things: Really receive an undertaking hazard the board culture. Grasp and exhibit proper endeavor chance administration practices, or traits. Create and reward interior hazard the executives capabilities, and Use venture hazard the board to educate the board basic leadership in both going out on a limb. Undertaking hazard the executives to be compelling must generally change the manner in which associations consider chance. At the point when undertaking hazard the board turns out to be a piece of the DNA of an organization’s way of life, the notice indications of a market roamed can’t go inconspicuous so effectively. At the point when each worker is a piece of a bigger hazard the board procedure, organizations can be substantially more flexible notwithstanding dangers. It is an essential exercise to adapt now, before the cycle reestablishes itself and organizations end up confronting the following cycle of business disappointments, slips by in hazard the board and weaknesses in administration. The cycle does not need to rehash itself as it generally has previously. Venture chance administration is a vital key to anticipating it. Venture chance administration, when planned and executed thoroughly and foundationally, can change future results. When it is rehearsed completely, venture hazard the executives does not simply help shield organizations from mishaps, it empowers better in general business execution. Impacts Of The Financial Crisis Financial Effects And Projections Worldwide Aspects Various pundits have proposed that if the liquidity emergency proceeds, there could be an all-inclusive subsidence or more regrettable. The proceeding with improvement of the emergency provoked feelings of dread of a worldwide financial breakdown. The budgetary emergency is probably going to yield the greatest financial shakeout since the investment funds and-advance emergency. The United Kingdom had begun foundational infusion, and the world’s national banks were presently cutting financing costs. Administrative Proposals And Long-Term Solutions An assortment of administrative changes have been proposed by financial specialists, lawmakers, columnists, and business pioneers to limit the effect of the present emergency and counteract repeat. In any case, as of April 2009, a significant number of the proposed arrangements have not yet been actualized. These include: Ben Bernanke: Establish goals techniques for shutting grieved money related organizations in the shadow banking framework, for example, speculation banks and mutual funds.
