Unit 4 – Discussion Board (75 points)

Due: Thu, Mar 5 |

Description

Primary Response is due by Thursday (11:59:59pm Central), Peer Responses are due by Saturday (11:59:59pm Central).

Primary Response: Within the Discussion Board area, write 500700 words that respond to the following questions with your thoughts, ideas, and comments. This will be the foundation for future discussions by your classmates. Be substantive and clear, and use examples to reinforce your ideas.

For this Discussion Board, please complete the following:

Replication is a mechanism to generate and reproduce data replicas at one or more sites of a distributed database. It is a unique but also critical function of any distributed database. Synchronous and asynchronous replication are the two most popular methods for replication.

Study the relevant content in the course materials and then investigate the Library and Internet for information about synchronous and asynchronous replication. Based on the results of your research, compare and contrast the main difference between the two in the following aspects of their implementations:

Replication architecture
Replication schemes

Use at least one specific example, ideally with some simple diagrams to demonstrate the difference.

Responses to Other Students:

Respond to at least 2 of your fellow classmates with at least a 200-word reply about their Primary Task Response regarding items you found to be compelling and enlightening. To help you with your discussion, please consider the following questions:

How would you justify a different perspective from your classmates on the topic?
How, additionally, would you defend your classmates position?
What critique do you offer your classmate in regard to clarity and thoroughness of their post?
Please address all prompts. When offering counterargument or justification, consider practice, theory, and examples from your own experience, reading, or current events in presenting your position.

For assistance with your assignment, please use your textbook, all course resources, and any external research and resources you have gathered.

Unit 4 – Individual Project (125 points)

Due: Sun, Mar 8 |

Description

Assignment Details:

A distributed database management system (DDBMS) manages the database transactions in which both data and processing are distributed among several sites. The DDBMS offers several advantages over the centralized DBMS. However, the DDBMS is also subject to some problems.

Study the relevant content in the course material, and investigate the Library and Internet for information about centralized DBMS and DDBMS. Then, based on the results of your research, evaluate the main difference between the two in the following aspects:

Suitable applications
System architecture
System functions

Also present 1 specific application example that you either have experienced or researched to explain how some of the differences may impact the decision of choice on what type of DBMS is more suited for that application. Defend the rationale behind your considerations.

Individual Project Rubric

The Individual Project (IP) Grading Rubric is a scoring tool that represents the performance expectations for the IP. This Individual Project Grading Rubric is divided into components that provide a clear description of what should be included within each component of the IP. Its the roadmap that can help you in the development of your IP.
