2 - Build Database Tables
Last updated 13/03/2024
When an application record is saved in Five, a MySQL database is created and Five automatically establishes the connection with the external database management system (DBMS).With your Five account running in the Cloud, you can have multiple databases connected to different database management systems.
note
In Five's Desktop version, you cannot have multiple databases for an application.
This documentation will explain how to create and add tables to the MySQL database for the Portfolio application via Five's Table Wizard. In total, five tables will be added. The Portfolio database model below shows the relationships between the tables.
The Sector and StockExchange tables have a one-to-many relationship with the Stock table and the Stock table has a one-to-many relationship with the StockPrice table. At this stage no relationship has been established with the Portfolio table.
