Create an application that calculates and display two raise amounts, which are based on an employee's current salary. The current salary will be entered by the user. The two raise rates are 5% and 8%. In addition to the raise amounts, the application should also calculate and display the employee's new salaries. Include a button in the interface that the user can click to clear the user input and calculated results from the screen.

Effective knowledge management systems can benefit an organisation by promoting the sharing of knowledge and ideas, improving customer service, increasing revenue and improving employee retention. The effectiveness of a knowledge management system relies on a well-designed knowledge management infrastructure which will provide the long-term foundation for these systems. Conduct additional research. Then, identify and describe the five components of a knowledge management infrastructure. Also describe how each component should be implemented in order to support the effectiveness of the knowledge management system.

An educational institution, which caters for distance learning students, wishes to develop a web application that will support their students. Students will be able to download all their course material from the system and upload their assignments to the system for marking. This will also be the primary platform which administrators and lecturers will use to communicate with students. The system is expected to be made operational from within one year after development has commenced. Briefly explain what will happen during the planning phase for the development of the web application described in the scenario at the beginning of the question.

CQ is an organisation that realised that they can save money by importing the raw materials in bulk from an overseas supplier who wishes to invest in South Africa. CQ has realised that although it will be highly beneficial to partner with overseas suppliers, it might be tricky to manage the relationships. They are considering the implementation of SAP’s Ariba suite of solutions to help manage this relationship. Conduct additional research on SAP’s Ariba suite of solutions. Then, by referring to any five of the operational and strategic requirements for a Global Information Systems (GIS), state how SAP’s Ariba suite of solutions can aid CQ in managing their relationship with the overseas suppliers.

Sony TV Manufacturer want you to design a program that will help their customers to check the price along with the dimensions for their products to be purchased. For this Carefully read all the instructions and follow the requirements. o Create a class called SONY_TV along with two constructors as follows: o A Default constructor to set the length of TV. o A parameterized constructor that will receive the width in float. o By using a friend function calculate the area of the SonyTV o Create a member function to calculate the price of the sony TV by multiplying the area with Rs 100. o Create a show( ) function to show the details of the purchased sony TV. In the main you will construct three objects that will show the use of the two constructors. After calling the constructor it will call the area function, and then the price calculation function.

Q.No.4 Sony TV Manufacturer want you to design a program that will help their customers to

check the price along with the dimensions for their products to be purchased. For this

Carefully read all the instructions and follow the requirements.

o Create a class called SONY_TV along with two constructors as follows:

o A Default constructor to set the length of TV.

o A parameterized constructor that will receive the width in float.

o By using a friend function calculate the area of the SonyTV

o Create a member function to calculate the price of the sony TV by multiplying the area

with Rs 100.

o Create a show( ) function to show the details of the purchased sony TV.

In the main you will construct three objects that will show the use of the two constructors. After

calling the constructor it will call the area function, and then the price calculation function.
