the group of graduates and adjust their activities. Such a picture really allows you to
reduce overload before protecting work and gives a chance to a better preparation.
Of course, all these materials are open, but students cannot change them. Therefore, the original remains with the teacher, and the copies are sent to the participants:
in the case of a diploma—to students, in the rest—to the headmen of the groups.
22.4.4 Preparation and Conduct of the BD Exam
Mandatory part of the database exam is tasks’ solving. The simplest, but undoubtedly,
a useful variant of the task is a SQL query to a given database. The stage of preparation
of the task (this is the teacher’s case) and the procedure for passing the exam (the
main participant is a student) are considered.
In preparation, the teacher identifies and describes the subject area, designs the
database structure, then formulates the request and writes its solution to the system
database (Fig. 22.15).
Note that no query condition is generated here. Automatically adding elementary
variations (e.g., attribute names and values) is not difficult, but reduces the write-off
protection.
The prepared examination material is offered to the students in the exam.
According to the exam ticket number, the student receives a problem to solve. The
difficulty of evaluation is that the right solution is not always the only one. Therefore, the validation criterion is that the query results match. With low probability, the
correct result can be obtained when the query is incorrect. However, a deliberately
incorrect request, of course, does not pass (Fig. 22.16). The correct answer is given
in Fig. 22.17.
