Why bottom-up database design approach is important?

The bottom-up approach starts with the data and goes on to develop the structure around it. Here the approach can use to avoid the duplicate and redundant data. We all know that if some piece of data is duplicated several places in the database, there is the risk that it is updated in one place but not the other. This will lead for data corruption. In the same time this will aids to prevent such anomalies while ensuring the integrity of data in the database. So we can say that bottom-up database design approach is really important.
