P6 Use appropriate software analysis tools/techniques to carry out a software

investigation and create supporting documentation.

We will have a tool that is used to investigate requirements that help create a holistic view of how the application will work and meet business needs.

1. Identify some countenances of the Tune Source project.

• Stakeholders: include individuals and groups related to the Tune Source project or have project related impacts such as: ✓ Team leaders, project managers and developers who need to meet all customer needs and improve and upgrade to help users have the best look and experience. ✓ Sponsors of the project: In addition to Carly Edwards - one of the individuals contributing to the cost support of the Tune Source project, there are also others are also investors and shareholders give money to implement the project. ✓ Company leaders include John Margolis, Megan Taylor and Phil Cooper who have strong passion, relevant knowledge about the music industry and have extensive relationships with many companies. Entertainment other music recording will help increase the opportunity to collect and select rare music, while increasing the number of users more. ✓ Users : are those who will have access to the system's rare music archive. They will also have the right to raise their own views to evaluate the quality of the end-stage application and provide suggestions for developers to improve their products.
• Cost : is the amount of money that needs to be maintained and used for items in a Tune Source project. ✓ Costs for applying new technologies to the application, updating the system. ✓ Costs for the development team. ✓ Costs for running ads. ✓ Cost of gift card programs, promotions and discounts. ✓ Costs for the construction of kiosks and system maintenance.

9 | P a g e Assignment 2 – SDLC – Nguyen Duc Dung ✓ Cost of infrastructure maintenance for the application, for servers, for the system. ✓ Costs for repairs.

• Security issues. ✓ Message, code via phone number and email. ✓ Security question. ✓ Payment verification. ✓ Strange access detected. ✓ Two-factor authentication. ✓ Prevent an attacker from accessing data without permission. ✓ Prevent, protect any network attacks such as Dos or DDos from outside.
• Problems with the old system: ✓ Like other cases, when the technology is too old to make the system slow, slow, updating and replacing outdated equipment and tools is a must.

2. Requesting an investigation use Case Diagram.

The following is a picture of the shift diagram that was used in the system, including the steps to authenticate login, access to music store, listen to music, pay, user profile and some other functions: From the table above we can understand that, if users want to listen to the fullest of copyrighted and highest quality songs, users will have to register so that they will not be interrupted when enjoying music. However, they will have to pay a very small amount to maintain listening to music, downloading music monthly. At the same time, if you register to use, they will enjoy the VIP privileges of VIP members.

3. Requirements investigation flow chart.

To access the criteria to determine the content of the Tune Source project, we can use the flowchart. First, we need to understand the meaning of the diagram: It is understood that the diagrams can help us carry out all the processes in this project, it will be shown completely in the following figures. Box format varies depending on the image. It will only follow the directional arrows for the purpose of analyzing, designing and classifying work buttons and managing tasks and programs. Below is the Tune Source project flowchart, which will help people understand how the program works in this project and how the owner and manager can manage the entire system. website.

12 | P a g e Assignment 2 – SDLC – Nguyen Duc Dung The above chart has been applied to two types of users: registered users and unregistered users. Registered users will have the right to listen and download the full version of the music, while those who have not registered, they will also have the right to listen to the music for 10 seconds to make their final decision about. download music, subscribe to the right to use the full features and enjoy all the incentives.
