What is RTTI?
RTTI means run time type identification. It is the process of identifying the type of an identifier or an object during runtime which is not known during compile time. Through this, we can hide the implementation details of a particular identifier or an object at the user level during programming so that it ca be distinguished during runtime and used further.Object persistency is acheived through RTTI
What are methods in programming?
A method is simply a name we often use when referring to a virtual function in object oriented programming. We can define virtual functions for any class method which we expect to be overridden by a derivative of the class. Even if the exact runtime type of an object is not known but we hold a reference or pointer to one of its base classes, and unless we specify otherwise, implicitly invoking any method of that base class will invoke the most-derived override of that method, thus objects behave according to type even when that type is not known at compile time. This is known as runtime polymorphism.
Where to use polymorphism?
Polymorphism is used whenever you wish to achieve specific behaviour from a generic object, where the object's actual type may not be known or would be impossible to determine at compile time. By declaring virtual methods in the generic type (the base class), and overriding them in the derived type, you ensure that the derived object does "the right thing" regardless of its actual type, and regardless of whether the method is called directly or indirectly via the base class. With polymorphism, there is no need to determine the actual runtime type of the object, you get that for free simply by calling the appropriate virtual methods.
Can weak entity be converted into strong entity?
The primary key of a weak entity set is formed by taking the primary key of the strong entity set on which its existence depends (see Mapping Constraints) plus its discriminator. A strong entity set has a primary key. All tuples in the set are distinguishable by that key. A weak entity set has no primary key unless attributes of the strong entity set on which it depends are included. Tuples (a particular row) in a weak entity set are partitioned according to their relationship with tuples in a strong entity set. Tuples within each partition are distinguishable by a discriminator, which is a set of attributes.
The base class of an object is known as which one what?

What is entity known as?
An entity is an individual, organization, or object that is considered to be separate and distinct. In business or legal contexts, an entity can refer to a company, corporation, or institution that has its own legal existence.
What is a gugin?
There is no widely recognized entity or object known as a "gugin." It is possible that it is a misspelling or a term that is not commonly known.
What is schema object of database?
We know that schema in the database is refer to the basic design of that database and is stored in an object . That object is known as schema object of database.

What is dynamic dispatching?
Dynamic dispatching, also known as late binding, is a technique used in object-oriented programming where the method to be called is determined at runtime based on the actual type of the object, rather than at compile time. This allows for flexibility in the behavior of objects and enables polymorphism.
What is Entity instances?
Entity instance is a single occurrence of an entity type. Also known as an instance. Unlike entity type, many instances of entity type may be represented by data stored in the database.
The minimum distance between two object before they are seen as one object is known as?
The minimum distance between two objects before they are seen as one object is known as the resolution limit or the resolving power of the imaging system. It is the ability to distinguish between two separate objects rather than seeing them as a single entity.
What is execution time error in C programming?
Also known as a runtime error. These are errors to do with a program as it is running rather than when it was compiled. Runtime errors are usually because the programmer overlooked something. A hanging (floating) pointer as an example. Overwriting the bounds of a buffer is another. Runtime errors often cause crashes but a runtime error can exist for a long time (years) before it makes its self known. A debugger is a good tool for catching runtime errors but ultimately it is up to the programmer to not mess up in the first place.
Why is visual basic considered as a object oriented programming?
Visual Basic's form applications use objects such as Buttons and TextBoxes, these are known as objects, hence the name Object-Oriented. It is different to command line interfaces which only use text to communicate with the user, such as Command Prompt.
Why is the moon known as the earths natural satellite?
The moon is considered Earth's natural satellite because it orbits around Earth, just like human-made satellites orbit around Earth. It is the fifth-largest moon in the solar system and plays a significant role in influencing Earth's tides and stabilizing its rotation.
What type of account would be personal in Accounting?
Any entity which can be represented by name of an individual or entity is known as personal account in accounting parlance.
