7.4 Operating Multiple Shunsaku Files in One Transaction

This section explains how to update data using multiple Shunsaku Files in one transaction.

This section uses the example of the employee information management system of a company which owns three factories (from Factory A to Factory C) to explain how to operate multiple Shunsaku files in one transaction.

Taking an account of the 'data relevance', the structure of Shunsaku File is set as below.

• Set fileA, fileB, and fileC for each factory
• Set fileD as the aggregated result of all employees

Assume that one employee is added in FactoryA. It is necessary to add the employee's information into fileA and fileD which is the aggregated result of all files. However, the update of these two files has to be done simultaneously. In this case, data manipulation by operating multiple Shunsaku Files in one transaction is used.
