For tens and millions database design is different, because this project is based on small and medium-sized software development framework to design, the record volume is relatively small, so the database design considerations are: integration with

How many bytes of an empty class are in memory? How big is it if I join a member function? What part of this member function is stored in memory? How much memory space a class object needs to occupy. The most authoritative conclusions are:* Total

InheritedInheritance: The inheritance of classes, which is that new classes get existing features from existing classes. The original class is called a base class or parent class, and the resulting new class is called a derived class or

second, what is big and small endThe definitions of Big-endian and Little-endian are as follows:1) Little-endian is the low byte emissions in the memory of the lower address, high-byte emissions at the high address of the memory.2) Big-endian is the

Because the CLR does not support multiple inheritance, it provides a "shrinking version" of multiple inheritance through the interfaceAnd the inherited and derived formats differ from C + +1. In C + +, if a function of the base class is virtual, the
