Crow’s Foot ER diagram for Tiny College:
The following data model shows the solution for the given question.
Explanation:
- In the above data model, the overlapping constraint (o) is used as a category symbol. Here the “Employee” supertype entity has optional subtype entity.
- The “Professor” and “School” are the current data entities which mean the user can get the data from the current

Dijkstra's Algorithm (part 1). Consider the network shown below, and Dijkstra’s link-state algorithm. Here, we are interested in computing the least cost path from node E (note: the start node here is E) to all other nodes using Dijkstra's algorithm. Using the algorithm statement used in the textbook and its visual representation, complete the "Step 0" row in the table below showing the link state algorithm’s execution by matching the table entries (i), (ii), (iii), and (iv) with their values. Write down your final [correct] answer, as you‘ll need it for the next question.
