摘要:
This order placement and payment settlement system provides secure transactions in online shopping by means of the intermediation of settlement bodies that authenticate buyers and sellers, allowing each party to conduct business with confidence in the other. The buyer's computer or other data terminal accesses the seller's server to obtain purchase order information and transmits such information as is required to the server of the settlement body. On the basis of that information, the server of the settlement body references buyer credit databases provided to it and then transmits the purchase order to the seller's server only when the buyer is capable of making payment. The settlement body server also uses a trustworthiness ranking of the seller to determine the timing of settlement and effects settlement unless the buyer objects to settlement before that time. The system thus provides both the buyer and the seller with enhanced confidence in the integrity of the transaction.

This data backup and recovery system enables backup and recovery of data at low cost and in short periods of time. The system is comprised of a primary system that updates the source data and one or more secondary systems that back up the source data. The secondary systems may be installed in the vicinity of the primary system or at a remote location. The secondary systems have the same logical configuration as the primary system and perform backups by acquiring the most recent data in real time. The update histories maintained by the secondary systems may be used to restore the primary system to any given state at an earlier point in time. Using a secondary system as a referential tool enables load distribution; the backup processing of the secondary system may then be suspended to perform referential batch processing while it is detached from on-line processing.

Conventional information storage systems are subject to numerous practical constraints such as contiguity in the physical locations of blocks and the requirement that storage blocks be created in advance. Information retrieval in these systems has required the creation of indices, which take a long time to generate, and the structure of these systems makes them prone to deadlock since the indices are updated and the range of exclusion broadened when the referent information is modified. This invention utilizes the random access facilities of semiconductors to achieve high speeds and minimize the maintenance load. This invention introduces location tables and alternate-key tables to replace these indices. It also stores multiple records in a single block and can handle variable-length records and spanned records. The location tables manage the storage blocks. An alternate-key block is made up of a substitute key and its block number and the primary key value, either of which may be used to retrieve a target record by searching this table. Binary search is a well-known high-speed method of querying tables, but other methods may be used as well.
摘要:
While scalability in database processing may be achieved gradually and at low cost, to achieve high scalability of several thousand times. This database accelerator holds on an accelerator system copies of location tables, which correspond to primary-key indices, and alternate-key location tables, which correspond to alternate-key indices, for a primary system that performs data updates. When a location table or alternate-key location table on the primary system is modified, updates are synchronized to the location table and alternate-key location tables on the accelerator system. The data itself is held only on the primary system. Major improvements in processing capabilities are achieved over serial processing by distributing processing requests among accelerator systems.
摘要:
A data storage/retrieval system which does not use conventional indices, but utilizes the random accessibility of semiconductor devices. The system comprises a location table for managing storage blocks and making access with a main key and an alternate key table for making access with an alternate key to perform high-speed access, minimize the load during maintenance, and to realize high speed storage/update/retrieval. In principle, a plurality of records are stored in one block. This system can also handle variable length records and spanned records.
摘要:
A re-organizing system for re-organizing a database while operating the system using "data storing/searching method" of the invention disclosed in JP 11-31096 A. In addition to a currently-used location table (LC), another location table (LN) is newly made. During unit processing, the entries in one or more blocks of the location table (LC) are transferred to the location table (LN), enabling re-organization of blocks where records are recorded and re-organization of main keys. Similarly, by using a re-organization pointer indicating the progress of the re-organization of alternate key indexes, re-organization of a database can be made without stopping use of the database while carrying out search, addition, update, and deletion of data using main keys and alternate keys.
摘要:
A method for precisely evaluating an individual or a group in an organization on the basis of numbers so as to realize a true meritocracy. The activities of an individual and/or a group constituted of one or more individuals in an organization are regarded as a sale object and converted into numbers by using a accounting technique as necessary. The numbers are processed by a computer so as to evaluate the individual and/or group based on the result of the processing. The business performance of an individual is converted into numbers by this evaluation method, and the evaluation is carried out objectively and fairly. By using this method, a reward such as the pay of an individual or a retirement allowance can be decided.
摘要:
A reorganization system permitting reorganization in an operating implementation of the data storage and retrieval system invention disclosed in Japanese Provisional Patent Publication No. 11-310096, Japanese Patent No. 3345628. The invention permits the reorganization of primary keys and blocks storing records by means of the provision of current location tables LC and new location tables LN and writing location table entries from LC to LN for one or multiple blocks in a given reorganization pass. Alternate-key indices may also be reorganized in the same fashion. Reorganization is performed continuously. The use of reorganization pointers to indicate during reorganization how far reorganization has advanced permits reorganization of a database without suspending the database while executing data retrieval, addition, updating and deletion by means of primary keys and alternate keys.
摘要:
This method of evaluation provides means of accurately evaluating individuals and groups within an organization on the basis of numerical data and for thereby instituting genuine meritocracy within the organization. The activities of individuals and/or groups comprised of one or more individuals within the organization are quantified as billables or by applying tools of accounting and the individuals and/or groups comprised of one or more individuals evaluated on the basis of computer output provided that quantification as input. Use of this method of evaluation and such quantification of individual performance enables objective and fair evaluation of the individual. Application of this method and system further allows determination of the pay, retirement or severance pay, and other remuneration of individuals.
