Creating an efficient conceptual data model requires specific steps to follow (Sharma, et al., 2010, p. 68):

• Develop an Entity-Relationship Diagram
• Determine integrity constraints
• Final model review

1. Discuss why it is important to review the final model. Consider the cases to make changes in the later stages of database development
2. There are several issues to consider when reviewing the final model. One of the issues is M:N relationships. M:N relationships should be removed while reviewing the final model. Discuss the problem/s of M:N relationships and how they should be resolved. Support your discussion with examples.

Your Discussion should be at least 250 words in length, but not more than 750 words. Use APA citations and references for the textbook and any other sources used.
