2 - Build Database Tables
Last updated 11/12/2025
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).
This documentation will explain how to 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.
