If we had to justify the rationale and the aim of the database approach, what would spring to mind?
- Data Independence: both, Logical data independence, Physical data independence.
- Data redundancy.
"Transparency refers to the separation of the higher-level semantics of a system from lower-level implementation issues."
- Thus, data independence is a transparency issue.
- For a distributed database approach there are other issues.
We want to choose and use those distributed DBMS that offer the highest level of transparency support.
