Er-designer provides a number of tools and features to help you create, reorganize, and customize ER diagrams, and it can also export ER diagrams in JPEG format. In this tutorial, you will learn to: Entity diagram (ERD) retrieved from the database in reverse Using table data in an ER diagram Routing Table relationships Lookup table Exporting an ER

A : the use of E-R method for database conceptual design, can be divided into 3 steps: First, the design of local E-R mode, and then the local E-R model integrated into a global E-R mode, and finally the global E-R mode optimization, get the final E-R mode, that is, 1, a university realizes the credit system, the student may choose according to own circumsta

AssociationThe plot is the same as the Sequence Graph in many aspects. Both are used to record the interaction of objects. However, the sequence chart is based on time, while the collaboration chart displays objects and their associations without emphasizing time. Collaborate graph display to eliminate InteractionInformation sequence. The difference between the two lies in this. Therefore, the relevant content of the sequence diagram is also applicabl

UML class diagram in layman's Author: Liu Wei, posted: 2012-11-23, Source: CSDN In the 13 graphs of UML 2.0, class diagrams are one of the most frequently used UML diagrams. Martin Fowler in his book "UML Distilled:a Brief Guide to the Standard object Modeling Language, Third Edition" (UML Essence: A concise reference to the model language South (3rd edition)) There is a p

1, what is UML UML class diagrams can quickly examine code structures. 2. Theme The use of UML class diagrams in Pycharm. 3. Preparation work (1) Pycharm version is 2.7 or higher (2) Installing the Python Interpreter (3) UML Plug-ins and UML class diagram plug-in installation and normal use 4. Prepare an example Create a Animals module and mammal.py file (Alt+insert→python Package, Python file) and enter the following code: Continue to add more class

[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

behavior and achievesSpecific interface. 1In component-based development (CBD), component diagrams provide architects with a natural form of starting to model the solution. The component diagram allows an architect to verify that the required functions of the system are implemented by the component.Ensures that the final system will be accepted.In addition, component diagrams are useful communication tools for different groups. The

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

Collaboration diagram of UMLCollaboration Diagram--communicationdiagram also called co-operation diagram, is an interaction diagram (Interactiondiagram). The emphasis is on the organizational structure between the objects that send and receive messages, and a collaboration diagram
