  • The schema describes the structure of the whole database.
  • It is also defines the characteristics of all records.
  • It also describes the future required fields and characteristics of the records.
  • It is a time consuming structure to create for database.
  • It is better for design a database structure and at the starting it is very careful to create the structure of database.
  • When creating the structure you can necessary to neglect the modification of future fields or attributes. The modification of fields or attributes in the database takes it later to create.
