Q: In a DBMS architecture, what does the term 'data independence' refer to?
Solution: Data independence refers to the ability to change the data structure without affecting the applications that use the data.
Steps: 5
Step 1: Understand that a DBMS (Database Management System) is software that helps manage databases.
Step 2: Know that applications are programs that use data from the database.
Step 3: Realize that data structures are the way data is organized in the database.
Step 4: Learn that 'data independence' means you can change how data is organized (the data structure) without needing to change the applications that use that data.
Step 5: For example, if you add a new field to a database table, the applications can still work without any changes.
