This section explains the basic idea to operate XML documents stored in Shunsaku by the direct access key.
The XML document stored in Shunsaku may have some keys that can be identified directly, such as employee number and account number. The database such as Symfoware server would be used for storing data and Shunsaku may be used as a search system. Since a search key that guaranteed an identity exists, user can store that search key in Shunsaku as an element of an XML document.
In Shunsaku this search key or the key that can identify the identity is called a direct access key. The search and update performance will be improved when a direct access key is used to operate XML documents stored in Shunsaku.
The following figure shows the Shunsaku system that using the direct access key.
A direct access key is an element node that the identity in XML document has been guaranteed.
There are three ways to manipulate the data using direct access key from APIs in Shunsaku.
The addition of data can be processed by the method shown in 4.2 Adding Data.
The data manipulation that specifies a direct access key can be used with the Shunsaku file. However, this data manipulation cannot be used with the domain for cross-search.
