What is Instance Recovery in oracle dba 10g?
instance recovery means getting the database to a normal functioning state. the recovery is needed when the database server crashes. the crash may be due to sudden power off.or somebody given the shutdown abort command in this cases what ever the changes that should happen with the database are not happened in a regular manner. so again when the database starts a process called instance recovery happens such as rolling forward the committed transactions and rolling backward the uncommitted transactons the set of transactions are already recorded in the files are called online redo log files this is called instance recovery in oracle 10g hope this helped
Should you capitalize government if it says teaches government?
No it shouldn't be capitalized in this instance.
Difference between copy constructor and assignment operator?
The copy constructor is used to initialize a new instance from an old instance, and is called when passing variables by value into functions or as return values out of functions. The assignment operator is used to change an existing instance to have the same values as the rvalue, which means that the instance has to be destroyed and re-initialized if it has internal dynamic memory.

Is backup and recovery necessary?
"Backup and recovery services are crucially necessary if you run a business that deals in sensitive information. For instance, in healthcare, if you keep pt charts on a computer, you need to have them backed up!"

What is the use of static method?
Static methods are not specific to each instance of a class. This allows you to have functions which return the same output for the same input for each instance of the class.
Difference between member functions and static member functions?
Static member functions are used to provide functionality that is closely associated with the class but are not associated with any one instance of the class. Static member functions do not have access to a this instance pointer, and can therefore be called without instantiating any instances of the class. By contrast, non-static member functions are associated with a specific instance of the class and therefore have access to the this instance pointer.Static member functions can be likened to friend functions (with the same access rights), but are scoped to the class itself. They are often used in conjunction with static member variables.By way of example, consider the following class:class MyClass{int instance_variable;static int class_variable;public:int GetInstanceVariable() const { return( instance_variable ); }static int GetClassVariable() const { return( class_variable ); }};// initialise static member variable.int MyClass::class_variable = 0;Here, every instance of the class shares class_variable and we can access it without even instantiating an instance of MyClass:int x = MyClass::GetClassVariable(); // x == 0However, because class_variable is shared amongst all instances of MyClass, any instance of MyClass can alter its value. This can be useful if you need to know how many instances of MyClass have been instantiated, for example, simply by incrementing class_variable in every constructor, and decrementing it in the destructor. Thus the value returned by MyClass::GetClassVariable() tells you exactly how many instances exist at that moment in time.Static members functions are also useful when dealing with singleton classes. The typical model is as follows:class MySingleton{private:MySingleton(); // default constructorMySingleton(const MySingleton&) {}; // copy disabledMySingleton& operator=(const MySingleton&) {} // assignment disabledstatic MySingleton *instance; // the one and only instance of MySingletonpublic:static MySingleton& Instance(){if(!instance)instance=new MySingleton(); return( *instance );}static void Destroy(){if(instance)delete(instance);}}// Initialise static member.MySingleton * MySingleton::instance = 0;Here, an instance of MySingleton is created the first time you call MySingleton::Instance() and that one instance exists for the entire duration of the program or until you call the MySingleton::Destroy() static member function. This then guarantees that only one instance of MySingleton is ever instantiated at any one time. The class can then be fleshed out with non-static member methods that are only accessible via calls to MySingleton::Instance().
