Course Introduction：The "Server" drop-down menu in MySQL tool is selected to allow you to specify the database instance of the current operation to avoid misoperation. This feature is particularly important when you manage multiple environments (such as development, testing, and production); common uses include security testing code changes, differentiated permission management, and independent monitoring of performance; when switching servers, the application will load corresponding connection information based on the selected entry and establish a new connection; if you do not switch manually, the application will continue to use the previous connection, which can easily lead to misoperation; best practices include confirming server selection, clear naming, restricting permissions, using visual prompts or memo tags.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
