Who should be in charge of designing the database – team members, who understand the application requirements, or a database design expert, who may not understand the problem domain issues but does understand good database design? What would you suggest?

The database design master should be responsible for planning the database As a professional, he or she knows the right way to describe a specific database. What are the items that should and should not be included in the database? The colleagues are responsible for following the guidelines issued by the Manager of the Project.

If peers are left with the ability to explain, a significant measure of effect must take place in the middle of every person's thinking and may rapidly delay the overall progress. Therefore, a database design expert is the special case that should be the responsibility of the entire company.
