Overview
This exercise considers the application of a real relational database
system. Under the use of the RDBMS Firebird we want to use
simple SQL instructions for select and insert statements. After a first
analysis of the database scheme, there are tasks for the selection of
specific database tupel (rows of tables of the data base).
Furthermore we want to change selected database entries. All
executed tasks should be documented with help of a protocol.
