Question: What is the explanation?
- Database concurrency control and data security
- DBA tasks
- Technological advances in the field of databases
Based on your research and understanding, complete the subsequent tasks:
- Describe how the data is displayed and extracted.
- Outline three examples of databases that you use every day. For each database:
- Analyze three websites and outline your thoughts on how databases are used to provide information and data to the consumers of the websites.
- Based on what you have learned so far, discuss how you think the DBMS provides this functionality in the background.
- Highlight the information that you feel is worthy of a special mention.
- Compare the database designs of the three websites in terms of their features, performance, and usability.
- What should be completed first-application design or database design; or should they be completed at the same time? Provide sufficient reasoning to support your answer.
- "Web programming has an inherent problem with concurrency control." Do you agree with this statement? Why or why not?
- Discuss the possible solutions to resolve and manage concurrency control.
Solve these questions in details and provide examples to support your rationale.
