Use scenarios include code duplication, project size expansion, improved testability and reduced dependency. The application steps are: first understand the problem, then select the appropriate mode, keep it simple to implement, and can be reconstructed and optimized later. For example, Factory mode can be used to return different database instances based on configuration, thereby simplifying maintenance.

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.
