7. An association oversees a swimming lessons program in the city of Delhi. 7 course levels are offered: Level one is for beginners (usually 4-7 years old) and Level seven is advanced. Swimmers move to the next level when they pass a series of tests that are geared toward the level (e.g., front crawl for 30 feet). Courses are offered 3 times during the summer and monsoon in the spring season. Parents register their children by submitting a registration form(s) and a payment. The registration form contains the name of the child and the desired classes(s) and times. A parent may sign up a child for more than 1 course and time as long as the classes are not during the identical time period. For example, a parent may sign up a child for level two in the 1st summer session, level three in the 2nd summer session, and level four in the monsoon. A parent may submit more than 1 registration form per payment: 1 form per child. Draw a DFD to represent the registration process.

8.
a) Compare and contrast the modeling of data and behaviors in the traditional versus the object-oriented approach.
b) Management info Systems should facilitate decision making at all levels of management; every level requires info with various characteristics, and with differing degrees of probability. Your are needed to:
i) compare, briefly, the characteristics of info used in strategic planning with those needed for operational control and
ii) discuss the features of deterministic, probabilistic and adaptive systems. provide a practical example of every kind of system.

i) UML
ii) Context Diagrams
iii) Cohesion and Coupling
iv) Testing vs Quality Assurance
