What are the advantages and disadvantages of both top-down and bottom-up approaches to database design?
Can you tell me about the advantages and disadvantages of top-down and bottom-up approaches to database design?
Top-down or "traditional" database design starts by defining the overall organizational structure of the database, and then breaks it down into smaller, more manageable pieces. One advantage of this approach is that it is easier to maintain and modify the database since changes are made at a high level. One disadvantage is that it can be difficult to predict every possible use case or query that the database might need to handle.

Bottom-up or "agile" database design, on the other hand, starts by defining small, discrete units (such as individual tables) that can be combined flexibly to meet changing requirements. One advantage of this approach is that it is more adaptable to changing needs, but a disadvantage is that it may be less efficient and harder to maintain over time.
