A method of detecting and recovering from data corruption of a database is characterized by the step of logging information about reads of a database in memory to detect errors in data of the database, wherein said errors in data of said database arise from one of bad writes of data to the database, of erroneous input of data to the database by users and of logical errors in code of a transaction. The read logging method may be implemented in a plurality of database recovery models including a cache-recovery model, a prior state model a redo-transaction model and a delete transaction model. In the delete transaction model, it is assumed that logical information is not available to allow a redo of transactions after a possible error and the effects of transactions that read corrupted data are deleted from history and any data written by a transaction reading Ararat data is treated as corrupted.

Methods and apparatus for managing business interactions between opposing parties. Business interactions are mapped to service contracts. The service contracts are mapped to machine readable code. The machine readable code is defined by business transaction patterns and service interaction patterns. The machine readable code is consumed by an IT system. Management tasks associated with fulfilling obligations required by the business interactions are generated.

A system analysis program which can accurately analyze the operational status of a system without modifying functions of the system for providing services. A message analysis unit analyzes the contents of collected messages, and determines the times of occurrence of the messages, the process types requested by the messages, and whether or not each of the messages is a request message or a response message. In response to an instruction for model generation, a model generation unit generates a transaction model satisfying at least one limiting condition related to caller-called relationships between processes, based on a set of messages selected in accordance with a selection criterion based on the certainty of existence of caller-called relationships. Then, in response to an instruction for analysis, an analysis unit analyzes the processing status of a transaction based on a protocol log conforming to the transaction model.

The invention provides a logistic public information platform system, which is oriented towards production and manufacturing enterprises, drivers and logistics companies, has the functions of logistic information management, information retrieval, identity authentication, vehicle positioning, online insurance effecting and online traction, combines with a logistic information system and an electronic business system for realizing logistic information resource sharing and provides online parking lot one-stop service vehicle and cargo marching for a user. The system is an electronic information platform which is based on Internet and is developed by adopting a B2C (Business to Customer) mode, i.e. an enterprise and consumer transaction mode, wherein the electronic information platform comprises a foreground website and a background management system, the user can log in the foreground website for performing user registration, find required vehicle source information or cargo source information through an information searching function of the website, and submitting an electronic order for concluding a transaction, and an administrator can maintain the content of the foreground website through the background management system. The logistic public information platform system is suitable for logistic information transaction.

A method and apparatus for capturing trade-action data pertaining to credibility of participants, across multiple independent electronic marketplaces, in an online business. The invention utilizes a publicly or privately accessible service provider computer program that uniquely identifies user's credentials across multiple independent marketplaces, and non-intrusively records trade action data at specific stages of the transaction. Service provider computer program correlates, and analyzes recorded trade actions, and transaction patterns to create credibility ratings that show efficiency and effectiveness of the transaction performed. Credibility ratings aid in decision making process by disclosing true intention of participants to make a successful online transaction based on earlier captured trade actions to provide uniform ratings by capturing specific set of data across multiple independent exchanges and tracking uniform transaction patterns. In one or more embodiments the invention utilizes a computer program that interfaces with an exchange computer program for the electronic marketplace to provide notification of trade actions. Service provider computer program provides validation of user and exchange credentials by using locally stored encrypted data and provides mapping to identify user across multiple independent exchanges.
