Answer 1

Solution 1: The conceptual design of a database actually described the architectural design of the database system and it actually tries to describe different entities and their attributes, model the relationship between different them. On the other hand, the physical model actually tries to describe the database-specific implementation of the database on the basis of the data that is being stored in it.

Solution 2: Some of the advantages of using extranets in the field of business are:

• The information sharing is simple and the relevant documents can be easily shared using emails.
• With an SSL encryption or some standard encryption mechanisms, the data is actually secured over the extranet that is being used.
• They can be easily modified to the requirements of the organization and hence the productivity of the organization increases that provides an edge to the organization over its competitors.

Solution 3: Today information systems are playing the most crucial role in making sure that the business processes within the organization run smoothly without any problems. One such field is the e-commerce industry that allows the organization to keep a track of the orders and the stuff that can be sold by the organization. These systems are useful from the development of the application as well as the proper functioning of the sales and logistics within the organization.

Solution 4: Human Resource Management or HRM is the pillar of the organization that is dedicated to making sure that the human resources in terms of the employees and other personnel can be deployed to the business processes as well as different ventures within the organization and all of them are productive.

An intranet is a form of a network that is actually for the internal use of the employees within the organization. It is very useful for the internal communication of the employees and it is also safe as they are not using the internet and hence the chances of it getting compromised is a little low.

Internet on the other hand is a wide network of smaller networks that can are interconnected with each other in the form of a spider web. This allows the people all across the world to share the information and to use the services as well as the products that are present over the internet.
