Describe what partial and transitive dependencies are
What will be an ideal response?
A partial dependency is when the field only depends on one part of a composite or concatenated key. In other words, the field is determined by only one piece of a multi-field key. A transitive dependency is when a field depends on another field in the table which then that field depends on a candidate key, A?B and B?C, thus A implies C. If C is a candidate key and B is not a candidate key, this is a transitive dependency.

If you were in operations, which type of computer based information system would you use?
A. TPS B. MIS C. DSS D. ESS
Write a function that posterizes an input picture along a very specific process. If the red value is greater than 180, then set the pixel to red. If not, then check if the blue value is greater than 180, and if so, set the pixel to blue. If not, then check if the green value is greater than 180, and if so, set the pixel to green. If none of the three channels is greater than 180, set the pixel to black.
