analyze database concurrency control and data security. You will also study the technological advances in the field of database design.

Using the South University Online Library or the Internet, research the following:

• Database concurrency control and data security
• DBA tasks
• Technological advances in the field of databases

Based on your research and understanding, complete the following tasks:

• Outline three examples of databases that you use every day. For each database:
  • Describe how the data is displayed and extracted.
  • Based on what you have learned so far, discuss how you think the DBMS provides this functionality in the background.
• Analyze three websites and outline your thoughts on how databases are used to provide information and data to the consumers of the websites.
  • Compare the database designs of the three websites in terms of their features, performance, and usability.
  • Highlight the information that you feel is worthy of a special mention.
• 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.
