Overview of sample application
Let's develop the sales management application with Transactd PHP ORM. This example focuses on how to construct the application with complex transaction.
This application records increase and decrease in inventory, and total sales per day, every time sales is recorded. The daily summary table is not calculated by batch processing. It is recorded at the same time as saving sales record.
This sample shows how to create model, and basic usage of it. Interfaces such as View is omitted.
