7.1 Overview of Shunsaku File

This section explains the overview of Shunsaku file.

Shunsaku File is a function to increase the independence of each job when Shunsaku is used to create and operate multiple jobs. The Shunsaku File function makes it possible to arrange the director data of each director into groups that can be managed as separate Files. If the name of a Shunsaku File is specified in an application, that application can operate on that particular File. This makes it possible to limit the range of directors that an application can access, and to determine the individual application logic and hardware resources that are needed to create a job.

Files that are used in multiple jobs can also be associated together in single Domains. By specifying the Domain name in an application, it is possible to create jobs that can search across data used in different jobs.

Even if Domains are used, individual jobs perform data update processes on Files. Only data search jobs can be performed on Domains.

These File and Domain structures are referred to collectively as "Shunsaku Files".

The decision to use Shunsaku Files should be made on the basis of how much variation there is between jobs and the scale of the system. If the Shunsaku File function is not used, there is no need to specify Shunsaku Files in applications, and all director data will be accessible.
