I have an assignment for developing a hotel reservation system! One of tasks is to develop UML class diagram! However, in the task description it is written "Class diagram should represent your database" I am a bit confused about the rules, notations and etc... because I can't find any official UML class diagrams specifically for databases! Could you help me please? Kiran First I would like to brief you about the different types of classes for a class diagram into which one can view the entire system in a static view. Some classes are entity(model) classes which define the database model for

Let's say there is an PHP subsystem which uses only associative arrays to store some kind of structured data. So in fact there is no mechanism on language level to constraint those structures but you want to define them in your design with the UML. E.g.: A contact could look like this as an associative array in PHP: [ 'name' => 'John Doe', 'birth' => '2000-04-01', 'email' => 'john.doe@company.com', 'address' => [ 'street' => '123 Main St', 'city' => 'Anytown', 'state' => 'NY', 'zip' => '1234', 'country' => 'US' ] ] So I thought an diagram in UML could look like this: But someone might

As in title , I try to develop as few schemes for hte 3d graphics enigne -- ogre3d ; problem is the big picture scheme the class Ogre::Root requires quite many arrows descending from it. The model of joining boxes with relational arrows is they can only go in / out by specific points around the border ( called "joints" or something ) . Now, however I wouldn't try there are always 4 + 4 + 3 + 3 joints displaced at four sides , suppose I need to place seven arrows on one side, how do I do that ? EDIT: Here is what I mean, the "flies" or "crosses" to which one can bind the arrows are limited in

As Thomas Kilian described here , normal behavior of nodes of Activity diagrams with tokens is: A node becomes active when at all of its incoming InformationFlow connectors a token has arrived. When the node finalizes it sends single tokens along all its outgoing InformationFlow connectors. But also he added: There are special nodes like fork and merge which behave a bit different I know that behavior of "merge" node differs because it becomes immediately active by receiving first token and accepts one among several alternate flows. But what is the difference between behavior of fork/join

I'm trying to design UML Analysis Class Diagram for a college project. My UML Diagram looks like this: I have encountered two different problems: User can have multiple roles. A user with Manager role can manage other users and their roles. How to illustrate this association in UML? User uses SwipeCard to access a room. How to show this association in UML? You have a really good start to an analysis model. Some things I would do: Reify the association between User and Role (or make it an association class) called Role Assignment . Add a verb-phrased property name to every end of every

I have a question regarding creating a class diagram where I have used dependency injection. I have following code example: public class ReservationController : ApiController { private readonly IGetReservationService _getReservationService; public ReservationController(IGetReservationService getReservationService) { _getReservationService = getReservationService; } // GET list of all reservations public List<ReservationViewModel> GetReservations() { return _getReservationService.GetReservations(); } // GET single reservation by id public List<ReservationViewModel> GetReservation(string
