My main goal was to create a development platform with Oracle Apex application, the database will store the necessary information about all employees auto testing stations in which responsibility is being periodical inspection certificates.  As well as the possibility to perform operations required by deletion, addition, modification of data on the period of activity of the person licensed or personal data which are visible by pressing the "experts". The main purpose is to monitor people who have the certificates as periodical inspection, when the license was issued, when it expires, who would have been issued at that station is employed, etc and found the use continuously existing information with regard to the work station and experts in these stations at any time.
