Convert this plain text to ER diagram : "Each office employs one or more dentists, hygienists, andreceptionists each of whom have an employee number. Patientsare free to use any dental office but, naturally, must makeappointments in advance. A record of all such appointments iskept which specifies the patient’s name, the date and time ofthe appointment and a list of services performed. Adultpatients have a SIN (Social Insurance Number) but theirchildren typically do not. Each office provides specific services(e.g. cleaning, filling, X-rays, extraction, etc.) to the patients andbills them accordingly. Performing certain services consumessupplies (e.g. floss, amalgam, X-ray film, etc.). Such suppliesare purchased from a variety of suppliers each of whom isidentifiable by a unique supplier code. The current amount ofeach type of supply available is tracked so that when suppliesrun low, a new order may be placed with the appropriatesupplier. Patients are allowed to run accounts but…
(a) Modules can be taken iff (if and only if) they have more than seven students registered. (b) The assessments for a module must total 100%.
The default cutoff value in the two-class classifier (i.e., C1/C2) is 0.5. Thus, if the probability of a record being a class C1 member is greater than 0.5, that record is classified as C1. It is possible to use a cutoff that is greater or lower than 0.5. In general, lowering the cutoff value will result in a decrease (no change) in the classification error rate for records that are truly C1. Note that is not an overall error rate. True False
A student management system is defined below: With the help of the registrar, a new student establishes his/her account. A student can register classes of his/her choosing during the registration period. If the system found there are pre-requisite violations the student will be de- registered from the violating classes. A student who was de-registered up to three times will be warned. A student whose GPA is between 2.0 to 2.3 is also warned. Students who are warned must see the student adviser to remove the warning. A student whose GPA is less than 2.0 or who was warned three times or who has one outstanding warning without seeing the adviser for one semester will be suspended. A student can apply for graduation or transfer to other schools. If the student passed the graduation check by the registrar, she will be put on the list of graduating student. Graduating students whose GPA is higher than 3.5 are put in Dean's list, those higher that 3.9 are put in President's list. Anyone who…
