Assignment brief Polly Pipe is a water sports provider and installer based in Braintree, England. They need you to design and implement a database that meets the data requirements. These necessities are defined in this scenario and below are samples of the paper records that the Polly Pipe preserves. Polly Pipe is focused in placing aquariums at business customers. Customers can request several installations, but each installation is tailor-made for a specific customer. Facilities are classified by type. One or more employees are assigned to each facility. Because these facilities are often very large, they can include carpenters and masons as well as water installers. The facilities use equipment such as aquariums, air pumps and thermostats. There can be multiple computers in a facility. Below are examples of paper records that Polly Pipe currently maintains.

Activity 3. Provide a suitable test plan to test the system against user and system requirements. provide relevant test cases for the database you have implemented. Assess how the selected test data can be used to improve the effectiveness of testing. Note:- Learner needs to give expected results in a tabular format and screenshots of the actual results with the conclusion Activity 3. Get independent feedback on your database solution from the non-technical users and some developers (use surveys, questioners, interviews or any other feedback collecting method) and make recommendations and suggestions for improvements in a separate conclusion/recommendations section.
Activity 4
Produce a technical documentation and a user guide for the developed database system. Suitable diagrams diagrams (Use case diagram, class diagram, flow charts, DFD level 0 and
