A multiplicity adjustment agent collects request information database from a sub-system including an element of a system to be monitored. An individual sub-system's multiplicity adjustment server sorts and merges request information collected from each sub-system for each element/request path. An integrated multiplicity analysis server calculates a necessary multiplicity on the basis of the request information.

Multiplicity adjustment system and method

In a database system of a client-server arrangement, a database server operating in a server outputs data to a storage device. Here, the data stores in a database that is requested by a user application operating in a client. The user application refers to the storage device to which the data is outputted, to obtain the data. Thereby, the data managed by the database server is passed to an application at high speed in the database system.

Method and system for managing database having a capability of passing data, and medium relevant thereto

A database processing method for defining and operating data of file reference type which references a file. A column data insert request for specifying position information indicative of a storage location of a file and watch information for watching the file is received from a database client. A request for watching a file indicated by the position information is issued in accordance with the watch information. The position information and the watch information are stored in a database. The foregoing operations permit data in an external file placed outside a database to be treated as data equivalent to ordinary column data stored in the database to improve the integrity of the database.

Database processing method, apparatus for implementing same, and medium containing processing program therefor

In a database management system including a request reception server and a plurality of execution servers, each having a plug-in program module incorporated by a user, the request reception server analyzes a processing request from the user to determine whether or not the plurality of execution servers require currently unidentified input parameters when executing external functions in their plug-in modules, based on a definition information table created from descriptions of interface specifications for the plug-in program modules. When it is determined that the execution servers require such input parameters, an external function in the plug-in program module in the request reception server is executed to previously acquire the unidentified input parameters. The request reception server creates an execution processing procedure code, to be executed by the plurality of execution servers, assuming that the unidentified input parameters have already been inputted, and passes the execution processing procedure code together with the input parameters acquired by the request reception server to the plurality of execution servers.

A user defined ADT function (to be implemented by an embedded module assigned to the function) is executed with module calling triggers other than the execution of the ADT function described in an SQL statement in a database management method which allows the user to define a data type. By creating a proper execution procedure command package, an embedded module implementing an ADT function can be executed even if the function is defined in a format to return execution results as a set. The database processing method includes an ADT function analysis for selecting a procedural model for creating a proper execution procedure command package in accordance with an evaluation style and a non-ADT function called embedded module analysis for adding information on embedded modules called on module calling triggers other than execution of ADT functions. Examples of module calling triggers other than execution of ADT functions include module calling triggers specified by embedded module defining information which includes the evaluation style of the embedded module in addition to the module calling triggers.

Execution of user defined ADT function implemented by embedded module in

In an object-oriented database management system, a storage area of each data object is controlled using information indicating a storage area position of the data object in the database and a management serial number of the storage area. Each data object is provided with a directory object to keep therein information indicating a storage area position of the associated data object in the database and a management serial number of the storage area. In the database, the storage area of each data object is controlled using information denoting the storage area position in the corresponding directory object and the management serial number of the directory object.

Database management system

In a database management system for concurrently executing a plurality of transactions for access to a database, there is provided a user interface for defining a parent/child relationship between a plurality of pieces of data. The parent information of data is added to the data itself and to a storage location information of the data in the database. Upon access to data, lock control is performed by use of the parent information of the data, thereby performing representation of locked a object.

Lactoferrin hydrolyzates, having a decomposition rate between 6%-20% as measured by formol titration, for use as an antibacterial agent, and which have remarkably more potent activity than unhydrolyzed lactoferrin; and lactoferrin hydrolyzates, having a decomposition rate between 4-50% as measured by formol titration, for use as a tyrosinase inhibition agent, are obtainable by conventional methods for hydrolysis with acids or enzymes, and are stable to heating.

Lactoferrin hydrolyzate for use as an antibacterial agent and as a

An agent for tyrosinase inhibition which contains the effective quantity of enzymatic hydrolyzates of milk proteins, having a decomposition rate from 6% to 55% as expressed by the percentage of formol nitrogen to total nitrogen.

Method for inhibiting tyrosinase activity in treatment of skin

Lactoferrin hydrolyzates, having a decomposition rate between 6%-20% as measured by formol titration, for use as an antibacterial agent and which have remarkly more potent activity than unhydrolyzed lactoferrin; and lactoferrin hydrolyzates, having a decomposition rate between 4-50% as measured by formol titration, for use as a tyrosinase inhibition agent, are obtainable by conventional methods for hydrolysis with acids or enzymes, and are stable to heating.
