CSE :: Database System 2 - CS
- Reverse engineering is the process of reading a database schema and producing a data model from that schema.
- The data model produced from the reverse engineering process is a true logical model.
- Typically, there should be at least two different copies of the database schema used in the redesign process.
- Information systems and organizations do not just influence each other; they create each other.
- The NOT EXISTS keyword will be true if any row in the subquery meets the condition.
- Dependency graphs are diagrams that consist of nodes and arcs that show the dependencies of a database.
