I am a newbie in development and have encountered several problems in database development.
1: I made a connection to the database. From is running for half a day.
2: I added a button to connect to the database on the interface. When I click Connect to the database, the SQL chart is displayed.
3: The loading process is particularly slow when connecting to the database.
4: there will be 2-5 million data in the data table. If all the data is loaded into the memory, it will definitely affect the system speed. How can this problem be solved.

Thank you for disturbing your predecessors.
