Chapter 1 Introduction to UML Section 1 What is UML? A Unified Modeling Language (UML) is a set of graphical symbols that help people describe and design software systems (especially software systems built using object-oriented design) to build a single metadatabase. The above definition is too simple. In fact, for different people, the meaning of

In cases where data sets are frequently read, master-slave replication helps improve the performance of data access, enhancing the ability to recover from read operations, but the data is lost once the primary node is faulted 3) Peer Copy Without the concept of a master node, all replicas have the same status, can accept write requests, and lose one copy without affecting access to the enti

I have always thought that UML is the statement of SA. Only sa should be familiar with UML, so I only have the concept of class digoal ratio ‧ Recently, I was busy handing over the program to other colleagues because I was about to renew the program.

One person can draw very complex and detailed class digoal and sequence digoal, the other has a poor grasp of digoal details, but on the other hand, the latter considers that the top and bottom layers of the elevator are different from the middle layers and cannot be described in the same class, who should I hire? It is certainly not a UML diagram that can be very beautiful, but let the elevator go to the groun
