Suppose we are given a dataset and need to design a database from it. In other words, we begin with a single relation schema containing all relevant attributes. Instead of developing an ER diagram, we decided to break this schema into multiple smaller, well-structured schemas based on functional dependencies. What is the process called when we break single schema into multiple smaller, well-structured schemas?
