Hello,
the purpose of my task is to track the modifications on a table. More precisely i want to know if a cell has been updated or a new row inserted. I know i can use an audit tables to do that but it is not convenient because with an audit table i have a long list with all modifications and it will be complicated to find what i want.
Therefore i want to know if this task is possible : when i selected a cell in the database ( using e.g oracle sql developer) i want to have the possibility to see the history of this cell. E.g: if the value of this cell has been updated i want to see in a contextual menu who changed this value and when and what was the old value.
I want to know if there any add-on for Oracle SQL developer or database tool that do that.

Oder if it is possible to have a database tool or an add-on for Oracle SQL developer that highlights a cell when this has been modified.

SQL> SELECT deptno, dname,
  2         VERSIONS_STARTTIME
  3        ,VERSIONS_XID
  4        ,VERSIONS_OPERATION
  5  FROM dept VERSIONS BETWEEN SCN MINVALUE AND MAXVALUE;

    DEPTNO DNAME          VERSIONS_STARTTIME       VERSIONS_XID     V
