...Com3FD3 - Assignment 1 Due 11:00 p.m. Thursday October 2, 2014 Quick Buck Financial is launching a new product. The product is a two-year, partial amortization, new car loan, intended to help restore the customer's credit rating. The amortization period is between six and ten years depending on customer preference and previous credit history. To make things easy for their intended customers, they will have twice monthly payments (on the 15th and last day of the month), to better align with their pay checks. Interest will be charged on the basis of an APR with monthly compounding (mentioned in the fine print). The amount of the loan will be between $15,000 and $40,000 based on the expected professional clientele. If they want to borrow more or less, they will have to use a different product. Required: Build an amortization table model that handles the above constraints and offers an interest rate between 9% and 11.5% APR* in increments of 25 basis points (¼ of 1%). Required outputs of; required semi-monthly payment, balance owing at the end of the term, and total interest paid must be shown to the client. The model should not accept any input that does not conform to the loan details. Assume that the users are experienced with Excel and that they will be showing the model to potential clients. *Annual percentage rate with monthly compounding. A basis point is one percent of one percent or 0.0001. Semi-monthly means twice a month, 24 payments per year....

...Effect of Industry Characteristics on Financial Statement Relationships. There are various strategies for approaching this problem. One strategy begins with a particular company, identifies unique financial characteristics (for example, electric utilities have a high proportion of property, plant and equipment among their assets), and then searches the common-size data to identify the company with that unique characteristic. Another approach begins with the common-size data, identifies unusual financial statement relationships (for example, Firm (10) has a high proportion of receivables), and then looks over the list of companies to identify the one most likely to have substantial receivables among its assets. We follow both strategies here. Firm (10) has a high proportion of receivables among its assets and substantial borrowing in its capital structure. This balance sheet structure is typical of the finance company, HSBC Finance. Why do the capital markets allow a finance company to have such a high proportion of borrowing in its capital structure? The answer is threefold: (1) finance companies have contractual rights to receive cash flows in the future from borrowers; the cash flow tends to be highly predictable, (2) finance companies lend to many different individuals, which diversifies their risk, and (3) borrowers often pledge collateral to back up the loan, which provides the finance companies with an alternative for collecting cash if borrowers default on their loans...

...You don’t have to be tall and super thin. No matter what you look like: You too can become a Model! There are different types of models and you have to be realistic in your expectations! There are fashion models, teen models, plus size models, and commercial models. Whenever you look at any magazine, or newspaper ad that is not geared towards fashion you see commercial models. And commercial models look like normal everyday people. As a commercial model, you are not going to get rich. At least most people won’t. But it can be fun part-time work with benefits such as free clothes, great pictures, and usually local recognition. Last night, I participated in Aaron Marcus' Tele-seminar entitled "How to Get Acting and Modeling Jobs and Find Modeling Agencies". The seminar lasted about an hour. You could call in and watch it over the Internet. Aaron offers workshops that you can attend live, but of course he doesn’t come to Birmingham, AL Some of the things that Aaron covered in his seminar were: * How to be a model regardless to what you look like. * What it takes to be a working model. * What to focus on when starting out. You see commercial models in many types of ads. Everyday people are used all of the time posing as Doctors, Lawyers, Teachers, Athletes, etc. Figure out what look you fit and target your career at those types of roles. Once you figure out what type of model that you can be, practice, practice, practice. Gather pictures of looks...

...Database Modeling Tool INF322 Instructor June 27, 2011 Database Modeling Tool The company has grown exponentially over the past 6 months and needs to develop a new database to house its financial, inventory, and client data. It has been decided to build this new database in house rather than purchase a system from a third party vendor. As part of the development of this database it is in the company’s best interest to utilize a database modeling tool to help the design effort. Utilizing a database modeling tool will offer the following benefits: 1. Simple graphic representation of the data structure. 2. Visual work flow of how data will be entered, modified, and reported. 3. Bulk editor capabilities. 4. Database design generator. 5. Database reverse engineering. 6. Logical and physical data model reporting. The tool that looks to be the best fit for the company is CA Erwin Data Modeler r8. CA Erwin Data Modeler r8 was developed by Logic Works Inc.

The mandate hasn’t changed for manufacturers. They must develop more products with increasing complexity to address customer and competitive pressures. Yet, there’s no “give” in project timelines to adopt new technologies like 3D modeling to help them win. However, some manufacturers are not only adopting 3D modeling technology, but excelling at hitting their product development targets at the same time. How is it possible? Interestingly enough, it’s actually quite simple. Key Business Value Findings • Best in class manufacturers their hit revenue, cost, launch date, and quality targets for 84% or more of their products. • Best in class performers typically produce 1.4 fewer prototypes than average performers. • Best in class performers average 6.1 fewer change orders than laggard performers. • In total, best in class manufacturers of the most complex products get to market 99 days earlier with $50, 637 lower product development costs. Implications & Analysis How do they do it? • Best in class performers are 40% more likely to have engineers use CAD directly to ensure they stay close to the design. • Best in class performers are 24% more likely to take advantage of extended 3D modeling design capabilities. They are 55% more...

...Healthcare Data Warehousing Doug Kelley Health Informatics I Professor Lu December 7, 2012 Abstract ` Dimensional modeling lays the groundwork for data warehouses. Dimensional modeling is a similar process to traditional Entity/Relationship modeling in regards to tables (entities) having joins (relationships) with other tables via primary keys. Dimensional modeling has been used as a standard in industry for decision support systems in other areas such as transportation, production, sales and marketing. (Parmanto, 1) Because healthcare has many complex events, it has lagged behind other industries in terms of data warehousing. This paper will discuss several techniques that can help overcome these complexities. Introduction A data warehouse has been defined as a database optimized for long-term storage, retrieval, and analysis of records aggregated across patient populations, often serving the longer-term business and clinical analysis needs of an organization (Shortliffe, 932). For a data warehouse to perform these roles, it must be architected or modeled appropriately. There are a couple of different approaches to modeling data warehouses. Dimensional modeling is becoming standard approach. Background Review Designing a data warehouse for healthcare presents many unique challenges for designing a database. These include such complexities as multiple diagnoses, multiple payers, multiple physicians; primary and secondary, and late arriving data, such...

The REA Accounting Model: Intellectual Heritage and Prospects for Progress ABSTRACT: Researchers often equate database accounting models in general and the Resources-Events-Agents (REA) accounting model in particular with events accounting as proposed by Sorter (1969). In fact, REA accounting, database accounting, and events accounting are very different. Because REA accounting has become a popular topic in AIS research, it is important to agree on exactly what is meant by certain ideas, both in concept and in historical origin. This article clarifies the intellectual...

...(online analytical processing) is computer processing that enables a Big data analytics Data modeling Ad hoc analysis user to easily and selectively extract and view data from different points of view. For example, a user can request that data be analyzed to display a spreadsheet showing all of a company's beach ball products sold in Florida in the month of July, compare revenue figures with those for the same products in September, and then see a comparison of other product sales in Data visualization Extract, transform, load (ETL) Florida in the same time period. To facilitate this kind of analysis, OLAP data is stored in a multidimensional database. Whereas a relational database can be thought of as two-dimensional, a multidimensional database considers each data attribute (such as product, geographic sales region, and time Association rules (in data mining) Relational database period) as a separate "dimension." OLAP software can locate the intersection of dimensions (all products sold in the Eastern region above a certain price during a certain time period) and display them.
