Multiple inheritance is not supported directly but it is achieved through the concept of Interface

In direct marketing, there is a direct interaction of the customers with the seller without any intermediaries. Here, the role of the intermediaries is nil. The medium used is more direct using telephone, mail, internet where the seller can directly reach out to the consumer. Examples of such marketing include telemarketing, email, voicemail marketing, door-to-door selling etc. This kind of marketing is more time saving as the problem of distance which may otherwise exist between the buyer and seller is eliminated and is also cost effective as it minimizes commuting costs.

A package is a collection of related PL/SQL objects. The package contains a body and a specification. The package specification has the declaration which is public and can be used in the PL/SQL sub programs inside the package.

The package body holds the implementation of all the PL/SQL objects declared in the specification.

Example of a PL/SQL Package.

CREATE OR REPLACE PACKAGE emp_data AS 

PROCEDURE add_employee (

      ename VARCHAR2,

      job VARCHAR2,

      mgr NUMBER,

      sal NUMBER,

      deptno NUMBER);

END emp_actions;

CREATE OR REPLACE PACKAGE BODY emp_data AS 

PROCEDURE add_employee (

       ename VARCHAR2,

       job VARCHAR2,

       mgr NUMBER,

       sal NUMBER,

       deptno NUMBER) IS

BEGIN

         INSERT INTO emp VALUES (empno_seq.NEXTVAL, ename, job, mgr, SYSDATE, comm, deptno);

END add_employee;

END emp_data;

Advantages of  PL/SQL packages :

Packages are easier for application designing, encapsulating data, additional functionality and better performance. An application has various modules which can be placed in packages and handled easier.

The advantage of equity finance for a company – raising money by selling shares – is that this money does not have to be repaid. However, new shareholders usually get to have a say in how the company is run. Despite these rights, equity is often seen as a risky choice for investors as they will lose all their money if the company doesn’t prosper. If it does well, on the other hand, they may see their stake multiply in value many times over.

Debt finance – money raised through loans – must be repaid eventually by a company, usually with interest, but lenders won’t be able to exert as much influence as shareholders over how the company does business. The debt of a reliable company is usually seen as a safe investment, but fixed repayment schedules means that there are few opportunities for large returns.

Employers often ask this question to gauge whether you are someone who enjoys your job and wants to perform well on the job. Simply explain what you like, and tell why you find these responsibilities to be rewarding.
