Objective UML is used to describe the entire design process of the system, and for this process produced a UML9 diagram: Use case diagram, Class diagram, object graph, collaboration diagram, sequence diagram, activity diagram, st

[Keyword] UML component Diagram The main purpose of a component diagram is to display the structural relationship between system components. In UML 1.1, a component represents an implementation project, such as a file and a runable program. Unfortunately, this is in conflict with the term component, which is more common and refers to something like a COM component. With the passage of time and the

Label:we need to consider the relationship between the data when we set up the database, in order to clarify the relationship between the data we need to do a uniform collation of the data. For the more complex database, we need to establish a database model, which can be divided into two steps: first, the structure analysis of the database and the use of tree, table and other descriptive data, and then analyze the database operation methods, rules and additions and deletions of the database ope

Objectiveclass diagrams and sequence diagrams are two of the most commonly used diagram in UML. I will make a detailed summary. In many books, or Web sites, when introducing the design of a subsystem of a system, many times, a simple class diagram is given to describe the relationship between the classes that make up the subsystem. This is sufficient to illustrate the importance of class diagrams. The basic

This is a creation in Article, where the information may have evolved or changed. First, the conclusion is listed in the front: 1.Golang performance can be very good, but some native package performance is likely to be retarded, such as RegExp and Encoding/json. If used in high performance requirements, we should optimize according to the actual situation. The use of 2.ON-CPU/OFF-CPU flame diagram is a sharp weapon of program performance analysis, oft

The "activity diagram" displays business or software processes as workflows through a series of operations. These operations can be performed by people, software components, or computers.The activity diagram can be used to describe various types of processes. The specific examples are as follows:Business flow or workflow between the user and your system. For more information, see user requirement modeling.T

Test Case Design White paper-Causal diagram methodAuthor:vince Source: Http://blog.csdn.net/vincetest I. Method Introduction 1. Definition: A method for designing test cases by using graphical analysis of various combinations of input, which is suitable for checking the various combinations of the input conditions of the program. 2.

Object-oriented dynamic modeling, four diagrams of behavior interaction between entities, State diagrams (Stage Diagram), Sequence diagrams (Sequence Diagram), activities (activity Diagram) in front of the blog, we have learned, Today we are going to study the collaboration diagram (Sequence

Defined system boundaries determine the boundaries between the inside and outside of the system. the protagonist represents the role played by the external object. An object can play several roles, so it can be represented by several protagonists. communication relationships are used to illustrate the participation of protagonists in use cases. A use case is a set of events that occurs when the protagonist completes a process through the system. Typically, a use case is a larger process, rath

UML Dynamic Model diagram describes various aspects of system dynamic behavior, including use case diagram, sequence diagram, collaboration diagram, activity diagram and state diagram. Here is a brief description of each diagram:u

UML defines the following 5 categories, 10 model diagrams. The first class is the use case diagram, the use case diagram describes the function of the system from the user's point of view, and points out the operator of each function. The second category is static diagrams, including class diagrams, Object diagrams, and package diagrams. The class diagram is us

Come on, let's move on to the dynamic map. A, state diagram A statechart diagram is used primarily to describe the dynamic behavior of an object during its lifetime. In other words, the system has a state, then the action, the transformation into a different state. To give a chestnut, the user is in the machine state, click the next Machine button, into the machine state. Of course, there may be insuffici

Interpretation of the object relationship diagram: A Brief E-R diagram refers to the three basic concepts of the object, relationship, attribute to summarize the basic structure of data, so as to describe the concept of static data structure. A E-R diagram is an entity-contact diagram that provides methods to represent

Many of the most common causes of software project failures are focused on poor communication or lack of communication between "project key stakeholders". When there is a lack of alliances between development agencies and business advocates, it is even more critical. Business people may know that they have a problem to solve, but the development leader receives only a general description of the business requirements and some specific requirements.In the UML modeling language, a "use case

The 16th Chapter Object diagramSometimes it is very useful to present the state of a system at a particular point in time. is similar to a snapshot of a running system. The UML object graph shows the objects, relationships, and property values acquired at a given moment.However, you should be wary of spending too much on the object graph. In most cases, they can be deduced directly from the corresponding class diagram and are therefore of little use.T

Fourth Chapter sequence diagramIn general, we will draw a sequence diagram of the relevant behavior of a plot, the graph will show the use case (using cases) may appear in some of the objects, as well as the transfer of information between objects. This chapter will be a simple plot to do all aspects of the sequence diagram of the relevant discussion. Suppose we now have an order and are ready to invoke one

The following is a Library management system state diagram, very typical, covering the use of all the elements of the state diagram, because the state diagram is relatively simple, directly from the view of the picture can be very well mastered. Suppose you want to understand the concept of the element rigor of the state diag
