Thus the subtype inherits data from the supertype o An object such as a car inherits information about each of its parts. If the parts are separated, the object ceases to be a car. Thus the supertype inherits data from the subtype o A link table is created to relate objects to one another, thus the link table inherits information from both object tables 8 Which of these would be an example of inheritance o A car and its component parts with additional qualities pertinent to those types of component parts o Vehicles with classifications based on the type of vehicle and additional qualities pertinent to those types of vehicles o Highways with classifications based on road jurisdiction state, federal, local with additional qualities pertinent to those types of roads o All of these are examples of inheritance o Exactly two of these are examples of inheritance 9 Which of these is an example of an association?

Every determinant is a primary key B. Table contains no constraints except domain constraints and key constraints C. No transitive dependencies D. All non-key fields depend on all key fields E. Column has unique name, each column has singular data type, no identical rows, no null, singular values only F. Does not contain an unrelated multi- valued dependency G.

Contains no related multi-valued dependencies 12 Which of these is not a type of anomaly addressed by the normalization process? What happens? Let's call these fields Artist and Painting. Assume that Painting is declared the Primary Key. What keyword s must be used with Artist to make this constraint possible?

In which clause will you find the tables that are being used in the query? Each record of A will exist in the output. If a value from B matches the join column in A, then it will be appended.

Each record of B will exist in the output. If a value from A matches the join column in B, then it will be appended. A and B will be matched if possible. If they cannot be matched, then A will occur with null fields for B and B will occur with null fields for A. Only records where A and B match for the join column will be produced 22 What is meant by cascading?

Create that table called Campuses with the constraint that each element of the campus ID must be UMS followed by two digits. You are making a table for shipping packages for a shipping company.
