101) What is inheritance explain? Inheritance is a process of creating a new class from already existing class. In inheritance process existing class is known as Parent / Base class, newly created class is known as Derived / Child class. In inheritance process, child class will get all the features of parent / base class. Man purpose of inheritance is code Re-usability and providing additional functionality/enhancement.

110) What is “Base” keyword explain? ‘Base’ keyword is used within the overridden method for calling the virtual function.
111) What is the purpose of Member Access operator (.)? We can access the class members by using member access operator after creating an object for the class. We can use ‘.’ Operator as Eg: Objectname.membername; Or We can use ‘.’ Operator with class name also (in case of static) as Eg: className.membername;

Public : Public Members are accessible anywhere in the class Protected: Protected Members are accessible within the same class and also in the derived class; derived class might be in same assembly or in different assembly. Internal: Internal Members are accessible in any class with in the same assembly but nor accessible in any class outside the assembly. Protected Internal: This is combination of both Protected and internal i.e. protected internal members are accessible in any class with in the same assembly and also from the derived classes outside the assembly, but not accessible from the Non – Derived classes outside the assembly.

(or) Why Properties are used? Properties will provide abstraction to the Data fields. Properties will provide security to the Data fields. Properties can be used to validate the data before allowing a change.
169) Explain how do you provide Data Abstraction using Properties? We can provide the data abstraction using properties by creating an object for the class (which contains private type data fields) in the other class. Generally we can’t access private data fields in other class, but by using properties we can able to transfer the data into those private variables and we can get the results finally also.

229) Is it possible to navigate within DataSet? Yes.
230) What is the drawback of passing the SQL commands directly to the database? Every time the user passes the SQL command first it compiled and then executes. If it contains any compilation errors the error information will be sent back to the front end directly. If there is no error the command will be executed and the result will be sent back to the front end. How many times you pass the command these two actions will be performed. In this approach the processing time will be wasted for unnecessary compilation of the command, burden on the database increases also.
