What is a simple Factory mode:By defining a class specifically, you are responsible for creating instances of other classes that typically have a common parent class. UML class diagram for simple Factory mode: The roles contained in the Simple factory model and the corresponding responsibilities are as follows: Factory class Creator: The core of the simple factory model, which is responsible for creating in

Overview A deployment diagram (deployment divisor) is used to display the physical architecture of software and hardware in the system. From the deployment diagram, you can understand the physical relationship between software and hardware components and the component distribution of processing nodes. The deployment diagram shows the structure of the runtime syst

This article reprint casually, Please retain the Source: http://blog.csdn.net/dylgsy/ UML class diagram relationships include association, aggregation/combination, dependency, and generalization (inheritance ). The Association is divided into two-way Association, one-way Association, and self-Association. Let's take a look at what these relationships are and what their differences are. 1. Association

foreign key operation, mapped to the primary key of the related table, the foreign key operation "Figure" is? Fk?.Association (associations)Correlation indicates that there is a relationship between two model elements, which is typically implemented as an instance variable in a class. A connector can contain named roles, cardinality, direction, and constraints on both ends. An association is an ordinary relationship between elements. If there are more than two elements, you can also use a diamo

. For this long square lattice, I have never understood what it actually means. I encountered an open-minded explanation on "Baidu Encyclopedia:You can think of activation as a "{}",From the beginning to the end, it can be understood as a method, an action; The lifeline is used to describe the time when an object exists. Add the destroy symbol below to delete the object or recycle the object. It is actually a Roman's dragon nest. When it's done, let's leave. There are four types of messages, but

, the object as a local variable, call the static method of the class. The class that is called within the parentheses of a class function is dependent on itself. Because this relationship is weakly connected, from the point of view of high cohesion and low coupling, such code is optimally organized, whether it is object-oriented or process-oriented.There is a special phenomenon in dependence, that is, interdependence. In the face of dependency interp

consistent.Just, the class involved in the association is logically a level, such as the student teacher above, but the aggregation involves the class is not a level.Look at the following example:It can be expressed as a has a/some B, at which point B is able to separate from a and exist independently.
