In a relational database, functional dependency helps ensure data integrity.
The functional dependency between product ID and price is straightforward in most tables.
Defining functional dependency can simplify complex data relationships in a database.
In normalization, we explore various types of functional dependency to avoid redundancy.
A clear functional dependency can streamline data retrieval in applications.
Database designers analyze functional dependency during the normalization process.
We must review the functional dependency before applying any changes to the schema.
However, due to its limited modeling capability, we may confront difficulties when modeling dynamic systems which involve complicated dynamic characteristics such as sequence dependency and functional dependency.
Jednakże ograniczone możliwości modelowania jakie daje ta metoda mogą prowadzić do trudności przy modelowaniu systemów dynamicznych posiadających złożone charakterystyki dynamiczne, takie jak zależność sekwencyjna czy zależność funkcjonalna.
Each student ID has a functional dependency on the student's name.
Functional dependency is fundamental for understanding how data elements interact.
