Questions

a. Classify the two alternatives in terms of what type of application architecture they use.
The first alternative in terms of application architecture is a client-based architecture. As it states that the downloaded tool will communicate with the DRUB server to select data and analyze, which is very similar to the client-based architecture where the clients tells the server what data to select and analyze and processes data will be sent back to the client for display.

The second alternative in terms of application architecture is two-tier client-server architecture. The application logic can be partitioned between the client and the server. The server is responsible for the data and the client, the application and presentation. Using the web browser the client will talk to the web server using a standard called HTTP (Jerry Fitzgerald, 2009).

b. Outline the pros and cons of the two alternatives and make a recommendation to Fred about which is better.
1. Client-based architecture:
a. Pros:
1. Much more inexpensive to implement as microcomputers are considerably cheaper versus mainframe.
2. Hardware of different manufactures or platforms can function together on the same network.
b. Cons:
1. Data traffic must be sent and received between client and host.
2. Due to the potential amount of information that must be sent between client and host, this can put a significant performance hit against the network, affecting all machines.

2. Two-tier Client-Server architecture:
a. Pros:
1. The cost of infrastructure is low as they place less of a load on networks and thus require less network capacity.
2. Performance is also increased without much effort. For instance if a organization decides to go for a system for server side to increase performance this can be done without affecting the user…...

Mini Case Ii Deals-R-Us Brokers (Part 1)

...Mini Case II Deals-R-Us Brokers (Part 1) Fred Jones, a distant relative of yours and president of Deals-R-Us Brokers (DRUB), has come to you for advice. DRUB is a small brokerage house that enables its clients to buy and sell stocks over the Internet, as well as place traditional orders by phone or fax. DRUB has just decided to install a new e-mail package. One vendor is offering SMTP-based two-tier client-server architecture. The second vendor is offering Web-based e-mail architecture. Fred doesn’t understand either one but thinks the Web-based one should be better because, in his words, “the Web is the future.” a. Briefly explain to Fred, in layperson’s terms, the differences between the two. b. Outline the pros and cons of the two alternatives and make a recommendation to Fred about which is better. How E-mail Works The Simple Mail Transfer Protocol (SMTP) is the most commonly used e-mail standard simply because it is the e-mail standard used on the Internet. E-mail works similarly to how the Web works, but it is a bit more complex. SMTP e-mail is usually implemented as a two-tier thick client-server application, but not always. Two-Tier Thick E-mail Architecture With two-tier thick client-server architecture, each client computer runs an application layer software package called a mail user agent, which is usually more commonly called an e-mail client (Figure 1). There are many common e-mail client software packages such as Eudora and Outlook. The user creates the...

Mis589 Chapter 2: Mini-Case I. Deals-R-Us Brokers (Part 1)

...CHAPTER 2: MINI-CASE I. DEALS-R-US BROKERS (PART 1) Question 1: Classify the two alternatives in terms of what type of application architecture they use. a. The first suggested solution is a client-based architecture since it’s the client that tells the server what data to select to analyze, making the client perform most of the work.   b. The later architecture is two-tier Client-Server architecture since it requires an application layer, in this case, a web browser and all processing is done by the server. The server is responsible for the data and the client, the application and presentation. Using the web browser the client will talk to the web server using HTTP standard. Question 2: Outline the pros and cons of the two alternatives and make a recommendation to Fred about which is better. Solution 1:   Client-based Pros 1. This method will be much more inexpensive to implement as micro-computers are considerably cheaper versus mainframe. 2. Hardware devices from different manufacturers/platforms can function together on the same network. Solution 1:   Client-based Cons 1. Data always flows through the network between the client and the server. 2. So much data traffic on the network between client and host could put a significantly slow down the network thereby affecting performance and response time. Solution 2:   Two-Tier Client-Server Pros 1. Performance in this method will be better as processing is distributed to multiple machines (in this......

...which the market is prepared to sell a specific currency in a Foreign Exchange Contract or Cross Currency Contract. At this price, the trader can buy the base currency. In the quotation, it is shown on the right side of the quotation. For example, in the quote USD/CHF 1.4527/32, the ask price is 1.4532; meaning you can buy one US dollar for 1.4532 Swiss francs.

Base Currency - The first currency in a Currency Pair. It shows how much the base currency is worth as measured against the second currency. For example, if the USD/CHF rate equals 1.6215 then one USD is worth CHF 1.6215 In the FX markets, the US Dollar is normally considered the 'base' currency for quotes, meaning that quotes are expressed as a unit of $1 USD per the other currency quoted in the pair. The primary exceptions to this rule are the British Pound, the Euro and the Australian Dollar. Bear Market - A market distinguished by declining prices. Bid......

...sausage named Vivio (5% of revenues). Storebrand products accounted for the additional 5% of revenues. While the bratwurst and breakfast products were sold throughout the United States via both national and regional brokers and distributors, the products had very little distribution in stores in the Northeastern markets. Since 2004, both the bratwurst and breakfast categories across all sausage producers had been flat (0% volume increase) nationwide, with little or no growth expected in the short term. Saxonville’s own brats sales had been flat, but in breakfast sausage the company had underperformed the market, resulting in a double-digit revenue decline; in December 2005, Saxonville ranked sixth out of eight national breakfast sausage brands. Italian sausage was the one category showing growth across producers in the retail sausage market, having grown at an annual rate of 9% in 2004 and 15% in 2005. Saxonville’s Vivio brand had matched that level of category growth; however, Vivio was available in just 16% of the nation’s large supermarkets, primarily in Boston, New Jersey, New York, Maryland, and South Carolina. ________________________________________________________________________________________________________________ Kate Moore prepared this case solely as a basis for class discussion and not as an endorsement, a source of primary data, or an illustration of effective or ineffective management.

...unprofitable relationships. Complicating the picture even further is the fact that even seemingly neutral electronic agents that provide personalized product recommendations to online shoppers can shape preferences in ways that benefit the seller—but not necessarily the buyer (Häubl and Murray 2006). In some cases, sellers offer customers very few choices by design (Which cable option would you like?), creating exchange asymmetries by the choices offered and denied to customers (see Kelly 2005; Lowery 1998, 142–47). On the other hand, customers may be offered an overwhelming array of choices (Which chips should I buy? Which jeans are best for me?), creating a “paradox of choice” (Schwartz 2004)—which also allows sellers to manipulate preferences. Not surprisingly, efforts to create “quasi-markets” for public goods and services, such as public utilities, exhibit many of these seller, or 1078 Public Administration Review • November | December 2009 rather “provider,” behaviors. Robust competition among providers is seldom found in sparsely populated areas (Warner 2006), and quasimarkets for local government services are seldom truly competitive (Lowery 1998; Smith and Smyth 1996). In other cases, the choices can overwhelm consumers, so that the benefits of competition are not fully realized. Consider, for example, that in the Washington, D.C., area, the Federal Employees Health Benefits Plan offered 26 benefit options to participants in 2008 (OPM 2008)—although the “paradox of choice”......

Markets include mechanisms or means for (1) determining price of the traded item, (2) communicating the price information, (3) facilitating deals and transactions, and (4) effecting distribution. The market for a particular item is made up of existing and potential customers who need it and have the ability and willingness to pay for it. Buyers and sellers of stocks or bonds or futures and options contracts use the financial markets to meet to buy and sell the products through a middleman exchange. What are the financial markets? That's a good question, because financial markets go by many terms, including capital markets, Wall Street, even simply "the markets". Whatever you call them, financial markets are where traders buy and sell stocks, bonds, derivatives, foreign exchange and commodities. These markets are where businesses go to raise cash to grow, companies reduce risks, and investors make money.
