Provided are an AP node to which a plurality of sensors is connected; and a DB node connected to the AP node. The AP node includes: a receiving unit configured to receive measurement data including values of a plurality of measurement items output from each of the sensors; a queue that stores a most recent value in units of measurement items of each of the sensors; a determination unit configured to refer to the queue and then determine whether the value of each of the measurement items has changed, every time the measurement data is output from each of the sensors; a transmission unit configured to, in a case where there is a measurement item having a value change, generate storage data including the value of the measurement item for each of the measurement items and transmit the generated data to the DB node; and an overwriting unit configured to overwrite the most recent value in the queue with a newest value of the measurement item. The DB node includes: a plurality of tables that stores a value included in the measurement data for each of the measurement items of each of the sensors; and a storing unit configured to store the storage data transmitted from the AP node in a corresponding table.

Data management system

A data management system including an AP server and a DB server. The AP server sends business data to the DB server and requests registration. The business data includes combination of parent data and a plurality of pieces of child data with mutual relevance, and each child data has ID of the parent data. In registering business data, the AP server first tries to register each child data, and requests registration of the parent data when a notification of registration completion of all pieces of the child data arrives from the DB server. When the notification of registration completion of any of the child data has not arrived, the AP server cancels the registration of the parent data. In referring to the business data, the AP server sets only child data with related parent data registered therein as a target.

Provided are a withdrawal management DB server, a deposit management DB server, and an AP sewer. The withdrawal management DB server includes a withdrawal table, a remittance table, a withdrawal/remittance table, and a remittance completion table. The deposit management DB sewer includes a deposit table, a remittance reception table, and a deposit/remittance table. The AP server registers withdrawal data related to an account number on the withdrawing side to the withdrawal table, registers a remittance ID to the remittance table, and registers a withdrawal ID and the remittance ID to the withdrawal/remittance table in remittance processing. The AP server registers deposit data related to an account number of a withdrawing destination to the deposit table, registers the remittance ID to the remittance reception table, and registers a deposit ID and the remittance ID to the deposit/remittance table. The AP server registers the remittance ID to the remittance completion table.

According to the process of the present invention for producing a garnet single crystal fiber, a crystal is grown while the direction of a seed crystal, corresponding to the direction of growth, is set in a direction having angles of at least 10.degree. from a direction equivalent to the &lt;100&gt; orientation, at least 20.degree. from a direction equivalent to the &lt;110&gt; orientation and at least 20.degree. from a direction equivalent from the &lt;211&gt; orientation. The resulting garnet single crystal fiber does not include a core, which is formed due to facet formation, and has an excellent optical homogeneity necessary for use in an optical device such as a laser device or an isolator.
