Database Connections

Description

Applications need physical database connection(s) in order to execute SQL commands.
New connections can be obtained by calling any one of the following functions : create_oracle_connection or create_postgresql_connection function.
Applications can have more than one database connection at the same time.
All connections must have a unique name called as "connection name".
If "connection name" is not provided by developer in source code, "default" is used as a default "connection name". As an example this happens when A data block does not specify its connection name in Form File (connection-name property).
