QUESTION
I am currently creating class diagrams in UML for a movie test domain. I would like to know if I am doing it right. Well, I have two alternatives (the first version in the first picture, the second in the second - I think the first one is better). I'm wondering if I've established the so-called "relationship owner" correctly, that is, from which class to which direction the relationships go. I also don't know if I didn't get multiplicity wrong (one to one, one to many etc.).
So on my domain I would like to have movies of course, the actors starring in those movies and directors. I wonder if the class name "Character" is good in this case, because I mean all the characters that take part in a movie - it can be director, actor but also for example "Batman". Maybe I should make a distinction here between "Movie Character" and then "Human", "Monster", whatever. But I don't know how to do it elegantly, will I then inherit from the Character class? I'm also wondering if I shouldn't put classes like City or Country together in one class called Address - but I wanted the classes to take attributes like in this case, that one is Master and the other is detail - and the relationship set in the right direction. I use only relations such as Inheritance and Dependency, I do not know if I should change something in this case.
Version 1
Version 2
Thanks in advance for any suggestions or advice!

Answered 2021-Jun-15 at 11:58Use inheritance very carefully. Prefer association over inheritance whenever your inheritance is not a permanent truth from the birth to the death of an object. ANd keep in mind that dependencies between classes do not make any promises about objects of those classes.
Some more explanationsSome clarifications on the UML syntax:
- I understand that your plain thick lines ended with a small hollow triangle represent a specialization/generalization relationship (aka inheritance). If this is correct, the triangle should be larger to avoid visual confusion. Moreover multiplicity makes no sense with inheritance and should be removed.
- I understand that with the dotted line you intend to represent an association with multiplicity. If this is correct:
- the association should be plain lines, because dotted lines are for dependencies, and multiplicity would make no sense.
- the meaning you give to the arrow head would be unclear. Do you use them to document navigability? In case of doubt, remove them. If you want to document ownership of the association end, use the dot notation instead. (we cannot say if it’s right or wrong, since it’s a decision on how your model sees the associations)
In view of your comments and the third model linked therein, there are some key UML semantics you need to keep in mind:
- Inheritance is an ultra-strong relationship which means "is (always) a". In your example, you may say that an
Actor
is always aPerson
, and hence, everything you say about aPerson
is also true for anActor
. By the way, you should avoid repeating inherited properties or methods, since it could create some ambiguity. - Inheritance is not a substitute for aggregation, composition or association. You can for example not say that a
CrewMember
(one person) is always aCrew
(a group of persons). ACrewMember
belongs to aCrew
but there are things that the crew can do together that the individual member can't. - Inheritance is not suitable if it's not always true. A
Character
for example may often be aPerson
. But not always;: you can have ghost characters, comic characters, robot characters, or animals. - Association means that there is some structural relation between some instances of the associated classes. For example, that one ore several persons live in one city, seems a very relevant assocaition.
- Dependency means that a class is dependent on another, i.e. without the other class it would not work or something would be missing. It's a statement about the classes and not the objects. I.e. If you meant to say that
Person
is dependent onCity
you just say that the class Person would not work without knowing about City (for example, because the operationsendPostCardFrom(city: City)
needs an argument of that type) but you do not say anything about persons X, Y and Z. If you want that X, Y and Z are related to city a, b, and c, you need an association.
About the model content, I'll not decide for you and there is no single truth. I therefore prefer to draw your attention at potential issues. I raise them in form of a question, up-to you to adjust the model based on your own answer:
Common issues between the both variants:
- Are
Actor
andDirector
reallyPersons
? In this case, what with the Persons that are Actors and Directors at the same time (g.g. Clint Eastwood) ? Or areActor
andDirector
just roles that aPersons
takes for a givenMovie
? - Is a
Character
really related only to 1Movie
? What to do with Indiana Jones, where the same character appears in several movies? - In a similar way, I wonder if there's really a single
Person
who lives in aCity
or if this should not be a many-to-many association?
- Are
Issues regarding the differences: `
- Is a
Person
in version 1 aCharacter
(inheritance) ? Or is aCharacter
a representation of aPerson
(association: represents) ? - Is a
Character
in version 2 really anActor
and by transitivity also aPerson
(inheritance)? Or is theCharacter
only associated with anActor
(association: plays) ?
- Is a
It's up to you to decide, but wherever I asked a question about association or inheritance, you should better think twice before using inheritance (i.e. prefer association/composition over inheritance)
QUESTION
I want your suggestions to start a simple software developement. I'm an intern student and i want to build, preferably, something that can be acceced with a user authentication to a specific number of users < 5 so that each one of them can access the analysis of the data that concerns him. Preferably :
- I want my users to get to the app through the browser
- The users are those who will provide data to the app through an upload file button so this latter can output the whole analysis
- the app should have a professional look
I'm supposed to work with these four-five peapole to determine what they want to see so i can prepare all the analysis code that corresponds to the right feeded data. genrally the data will have csv excel format.
I've start working with R shiny then I built a single shiny app for control and mangement director that contains a dahsboard with analysis/viZ elements. Then i figured out that I cannot add the feature of multiple users and neither the authotication feature. then I've start learning django but i realized that it's quite harder to do it in a month. I searched for django-plotly-library but I always hesitate to work and learn until the end.
well, now i'm open to learn anything that can solve this issue. I've been hesitating for a month to choose the right technology. I appreciate your suggestions and remarks.

I'm trying to get data from two separate objects in a single query using their WordPress IDs, but I'm getting GraphQLError: The ID input is invalid. Make sure you set the proper idType for your input.
