o A table column with this constraint is called the key column for the table. This constraint helps the table to make sure that the value is not repeated and also that there are no null entries.

What is a foreign key of a database?

  • To define the relationship between two tables (one is called parent and the other one is the child table) connected by columns, a foreign key constraint is used.
  • In this constraint the values of the child table must appear in the parent table, which means that for a foreign key, one table should point to a Primary Key in another table.
  • A table can have multiple foreign keys and each foreign key can have a different referenced table.

What is database normalization?

What Is De-normalization?

  • De-normalization is the process of attempting to optimize the performance of a database by adding redundant data.
  • It is sometimes necessary because current DBMS implement the relational model poorly.
  • A true relational DBMS would allow for a fully normalized database at the logical level, while providing physical storage of data that is tuned for high performance.
  • De-normalization is a technique to move from higher to lower normal forms of database modeling in order to speed up database access."
