Use Case Analysis of database Optimization Using Virtual Index and virtual Case AnalysisWhen we optimize the production database, we mainly optimize SQL statements, including equivalent statement rewriting. However, a large part of the optimization is related to indexes. If appropriate indexes can be used properly, the logical reads generated by full table scans can be greatly reduced to improve database pe

1 A single case pattern in a textbook We all know how a simple singleton pattern can be implemented: the constructor is declared private or protect to prevent being instantiated by an external function, and the internal holding of a private static class pointer holds a unique instance, and the action of the instance is performed by a public class method. The method also returns the unique instance of the Singleton class. Code on: Class Singl
