There are many data models for DBMS.
1- Which one is the most popular model used in DBMS ? Why is this model better than the other models ?
Give an example of an old DBMS that did not use this current popular model.
2- Suppose that you have a college that maintains data on Students, Courses, and Instructors. Use the model in
question 1 to describe the connection between the data. You should draw a simple diagram to show the relationship between
the data.

Problem 1 In simple predator-prey models, sinusoidal functions can be used to model the oscillating populations of two species of animals in the same environment. As the population of the predator species increases, the population of the prey species will decrease. If the number of prey gets too low, the population of the predator species will suffer from limited resources and start to decline. In this problem we will be modeling one population of rabbits (the prey) and one population...

Measures of correlation are used for identifying relationships between different types of variables. The most appropriate measure of correlation to use for any given data set, depends on the type of variables and levels of measurement. Which is best? For this discussion, begin by creating an example of a correlational study. Consider what variables it would analyze and what type of data would be collected. Then, develop a main response in which you address the following: Briefly identify the topic...
