Use Case: Execute SQL

###Brief Description#

This use case describes how a user can execute a SQL script.

###Basic Flow#

• The system opens a window where the user can enter a SQL script.
• The user enters a SQL script.
• The system validates the entered script and returns a confirmation of an execution from the database.

###Alternative Flows# #####Error Executing SQL Script#

If in the Basic Flow the system does not receive a confirmation of an execution from the database, the system displays a detailed error message. The user can choose to either return to the beginning of the Basic Flow or cancel the process, at which point the use case ends.

###Post-Conditions# If the use case was successful, a SQL script was executed and changes may have been made to the database. If not, the database remains unchanged.
