CHAPTER 7: DATA MODELING USING THE ENTITY-RELATIONSHIP (ER) MODEL Answers to Selected Exercises 7.16 - Consider the following set of requirements for a UNIVERSITY database that is used to keep track of students’ transcripts. This is similar but not identical to the database shown in Figure 1.2: (a) The university keeps track of each student’s name‚ student number‚ social security number‚ current address and phone‚ permanent address and phone‚ birthdate‚ sex‚ class (freshman‚ sophomore‚

Linear Thermal Expansion The term thermal expansion refers to the increase in size of an object as that object is heated. With relatively few exceptions‚ all objects expand when they are heated and contract when they are cooled. Perhaps the most important exception to this rule is water. Water contracts as it cools from its boiling point to about 39.2°F (4°C). At that point‚ it begins to expand as it cools further to its freezing point. This unusual effect explains the fact that ice is less dense

Levels of programming languages There are two major levels namely; 1. Low-level languages 2. High-level languages These two languages are sub-divided into five generations. 1st and 2nd gen - low level languages 3rd‚ 4th‚ and 5th – high level Xtics of low level languages. 1. They are easily understood by the computer directly i.e. they require little effort to translate into computer understandable form. 2. These languages are hardware oriented and thus not portable i.e. such that a

dimensions of disability (Reeve‚ 2002). Also the concept of disability is not linear (Reeve‚ 2002). People can be disabled when completing one task yet not disabled when completing another (). For example a deaf student may be disabled when asked to listen to a cd and write down how it makes them feel but not if they are required to look at a picture and write down how that makes them feel. So treating disability as a linear dichotomy is to

One agile software engineering method is Extreme Programming or XP. XP is a collection of values‚ principles and practices designed to rapidly create highquality software that provides the maximum value for the customer as quickly as possible. It is called extreme or XP because it takes commonsense principles

Evolution of Programming Languages Generations Most books and articles on history of programming languages tend to discuss languages in term of generations.This is useful arrangement for classifying languages by age.I agree that whatever a few of we ‘more mature’ software engineers get together‚ we cannot ever seem to agree on wht constitutes the generation of computer languages.We know that Formula Translation (FORTRAN) was probably a first-generation languges.Does that make FORTRAN 77 and WatFor

Linear Model of Communication It is a one way model to communicate with others. It consists of the sender encoding a message and channeling it to the receiver in the presence of noise. Draw backs – the linear model assumes that there is a clear cut beginning and end to communication. It also displays no feedback from the receiver. • For example; a letter‚ email‚ text message‚ lecture. There are two main linear model which are used to explain the human communication process. They are .

Etymology The first recorded use of the word “computer” was in 1613 in a book called “The yong mans gleanings” by English writer Richard Braithwait I haue read the truest computer of Times‚ and the best Arithmetician that euer breathed‚ and he reduceth thy dayes into a short number. It referred to a person who carried out calculations‚ or computations‚ and the word continued with the same meaning until the middle of the 20th century. From the end of the 19th century the word began to take on its
