1. A real object is something that is perceived as an entity and referred to by name; something perceptible by one or more of the senses; something intelligible or perceptible by the mind. A virtual object embodies the same concepts as real objects, but are created FROM concepts instead of giving rise TO them. 2. Freshman, Math Majors, and Commuters can be used as subclasses of the STUDENT class. 3. Transportation 4. A business class is a virtual class that reflects a class of objects (or concepts) in the real world. A utility class is a virtual class that serves the information system as a whole and, usually, does not reflect an object in the real world. So, the main difference is that a business class does reflect objects in the real world and a utility class does not. Some examples are: 5. The operation of a class is what it does or is capable of doing while its attributes are the properties, qualities, or characteristics that are associated with it. Attributes are mainly paired with values to define what an object or class IS while the operation is what it DOES. 6. It creates public and private areas, with the private attributes and operations being hidden and known only to the object itself. That is, how an object does something, and the data that it holds, are concealed within the same object, secure from abuse or misuse. 7. Simple inheritance is when an object inherits the behavior of a superclass, such as a tree inheriting the fact that it has a trunk. Multiple inheritance is when man made objects can have many parents, thus inheriting the behavior of many different parents. Such an example is a Swiss Army knife having a bunch of different unique functions. 8. Object oriented modeling is using an object-oriented approach to building conceptual and logical models of the system. Meanwhile, UML is a meta-modeling language, which means that UML models the models. 9. UML is mainly a language for object-oriented modeling. By that, it takes object-oriented concepts that object-oriented languages use, like classes, objects, etc. and represents it.
A Genre and Narrative Analysis of One Hour Photo (Romanek,2002) Genre What defines a thriller? There are generic elements, but no real strict guidelines for filmmakers.

systems can be broadly defined as the systematic approach to defining, measuring and reviewing the performance of individuals, teams and the organisation as a whole. (Schultz, cited in Kumari & Malhotra 2012; Singh 2012). For the purpose of this analysis, the focus will be primarily on performance management of individuals. Despite the terms being commonly considered interchangeable, it is important to recognise that the performance appraisal serves as one element of the system as a whole, which…
training and development activities are tied back to the company’s short term and long term goals and objectives -. Stone (2013, p. 365) notes that in order to enhance the effectiveness of training activities, it is essential to perform a comprehensive analysis. Training should have a clear assed return to give purpose to the training program and justify its existence. Based on the human capital theory it should only be provided when the economic benefits outweigh the costs. In order to increase the benefits…
IMPACT OF HIGHER EDUCATION ON THE ECONOMY ECON645-0340602 JULY 13, 2014 INTRODUCTION Does higher education matter to our economy? Is taking on the enormous debt to pay for a degree worth the gamble? Recent studies provided by Pew Research suggest that not only is a college degree the best investment towards future earnings, it promotes economic well-being and career attainment (Pew Research, 2014). Quantified benefits of a higher education include Private economic benefits:…
SES score and the predicted reading score is 9.65541 points. In other words, on average we expect that any given reading score might be “off” by about 9.64451 points. D. Correlation = r = b(sx/sy) = 4.75(.77634/10.31780) = 0.357; the squared correlation = r² = (0.357)² = 0.128. In correlation analysis this is interpreted to mean that 12.8% of the total variance in children’s reading scores is shared with the SES score and vice versa. In regression, it would be interpreted to mean that 12.8% of…
