to maintain. But do not abuse this one, repetition does not mean the repetition of the code, but the repetition of the function. For example, you have the same code to verify OrderID and SSN, but they represent different meanings. If you merge two different functions together, when OrderID changes the format, then the code that examines the SSN is invalidated. So be aware of this coupling, and don't say an

State Diagram
objects have behavior and status. The state of an object is determined by the current action and condition of the object. The state diagram Statechart diagram shows the possible state of the object and the transitions caused by the state change.Our model diagram establishes a bank's online login system. The login process involves entering a valid password and personal account and submitting it to the system for verification information.
The login system can be divided into

vulnerable connections (that is, passwords) for authentication systems. The industry is in great need of technology that can replace passwords. With embedded cryptographic processors, smart cards provide a very secure and easy-to-use authentication mechanism.
However, the deployment of smart cards also poses a unique challenge. The entire industry needs better products to deploy and manage complex authentication technologies. In his keynote address at the RSA 2006 Conference, Bill Gates demons

SendImmediately, which is true by default, sends a basic authentication header. If it is set to false, the system will try again upon receiving the 401 request (the server's 401 response must contain the WWW-Authenticate authentication method ).
When sendImmediately is true, Digest authentication is supported.
