Topic: Improving databases "an automated workplace of the Teacher" (academic year project)

Hello, respected ! I am again returned to a subject course because there were some problems concerning architecture of a DB.
The matter is that in this circuit it is too much dependences that is not pleasant to my teacher. But I at all do not know, how it is possible to get rid of them. Also the teacher "the Group" cycle-> "Students"-> confuses "Estimations"-> "the lesson Plan"-> "Groups".
Therefore, I ask your council...

There there are some communications.
(These are communications, instead of dependences)
To get rid of what it is not necessary.
it is passed...
There there is no cycle If you go on communications, arrows will be every which way.
It is the digraph, it is necessary to search for cycles on directional arcs.

Generally, forgive without errors the circuit, a small problem with phones of the student, the latent array of values, as though violation 1.
It is impossible to search by any phone connected to the student. But it not a gross error. In sense generally it is a gross error, but here she sold that probably such is not required.

Here it is softened by that, probably, such never is required.

At first, focus attention that the lesson Plan (front transfer Lessplans) actually a minimum the curriculum for a year!!! (and so that yes - if silently the student palmed off on me the circuit of a DB and was silent as the guerrilla - I too would tear it...)
Here one or the other:
1. The teacher himself not Copenhagen and the circuit of a DB more than from three tables (moreover and not a star) generally sees for the first time...
2. The teacher checked you - you understand that here is drawn or not...
Both that and another is treated defended)  the idea and its functionality (that to someone is not clear - it is necessary to explain and prove is and is called protection the diploma,  etc.):
- Lessplans - the schedule (plan), without this table the concept "automated workplace of the teacher" loses any meaning.
- To justify "Groups"-> "Students"-> "Estimations"-> "the lesson Plan"-> "Groups":
1. Communication "the lesson Plan"-> "Groups" is necessary for compilation of the schedule (the plan) as that, - the schedule should be irrespective of "Estimation" communication-> "the lesson Plan" (estimations can and not to be, estimations for occupation can be put down not everything, academic year yet did not begin, and the plan should be already unpacked).
2. "Estimation" communication-> "the lesson Plan" too specific for an estimation to the student is put for specific occupation in the plan which is defined through ID the plan, the estimation cannot be groundless, an estimation always to someone and for something.
3. That each group consists of students it it is obvious (a circle was shorted)...
Never be silent, prove the case, understood - teach the teacher that others did not suffer...

... I think the reason that you did not manage to inform to the teacher the correct essence of table Lessplans if the teacher thinks that it simply plan of a lesson (rose, , , , sat down, ) which is driven in upon a lesson fulfillment then really communication "the lesson Plan"-> "Groups" as the fifth wheel in a cart... Speech that goes about sense Lessplans as about planning of educational process in advance. Well and teachers in vain threw out...

How you consider, it is possible to make cross-table relationship "the Scientific plan" and "Schedule" one-to - to one? I thought of it, time you say that "Schedule" should be separately.

150698;
The last two questions entered me into a stupor...
Make simply the table in : who when, what estimation and in what subject received... All... Will be to you and electronic log and  the teacher in one bottle...
