    摘要: A database processing system using a multi-processor including a plurality of processor modules each having a local memory connected to an external shared memory. The database processing system includes a composite structure definition control part for defining an administrative processor module for controlling an access to a composite structure of a database which has a storage structure independent of a logical structure; and a maintenance/selection control part in an optimum control processor for providing a function of access-controlling a shared process and a local process when an access request arises for a database composite structure, and for dynamically switching the access control process for the composite structure according to the access frequency notified by each processor module. The system may further include an operation continuing control part for providing a controlling function for a recovery process for the composite structure of a database to be locally processed or shared-processed, and for performing a recovery process according to an access control process type for the composite structure of the database when the processor module falls in error, by replacing the erroneous processor module with another single processor module or a plurality of processor modules.

    摘要: A frame connecting member of a kite formed as a unitary body and of an elastic material comprises a main body whose front and rear ends are formed as projections provided with kite string mounting holes and whose center is formed as a base with a through hole in the longitudinal direction for a longitudinal frame member; and supports provided respectively at the right and left outer sides of the base on the same straight line in the direction which perpendicularly intersects the axis of the main body. The supports can be tilted to a certain angle with respect to the straight line and are provided with holes into which are inserted lateral frame members which perpendicularly intersect the through holes. The corners on the main body side of the supports come in contact with the main body so as to prevent any further tilting. The kite string mounting holes are directed in the same direction as that of the through hole of the base.

    摘要: A derived database processing system in a database processing device comprises a plurality of independent databases which can provide a plurality of users with a group of data to be shared for a common purpose. The derived database processing system comprises a dictionary for managing database logical definition information and database storage information in a secondary memory, a derived database registering unit for determining a definition frame of a new name without violating a definition frame of a name used in a schema definition which defines data in a database, a dictionary information manipulating means for referring to said dictionary when the manipulation target is a derived database, then selecting necessary components of said database, and a database processing procedure generating unit, in a binding process to optimize access routing in a database. The derived database processing means also comprises a database definition management means which replaces an old version of a database definition information with a new version by utilizing a consistency monitoring means and an integrity monitoring means associated with it.
