20100094919 | METHOD AND SYSTEM FOR MANAGING DATA TRANSACTION REQUESTS - In one embodiment, a method is provided for processing data transactions in a data store that includes databases. In this method, a data transaction request is received from a requesting computer. Different databases are then identified from the databases using a data access layer that defines an abstraction layer. The data transmission request is then split into multiple data transaction requests, and a part of these requests is then communicated to at least one of the identified databases. | 04-15-2010 |
20100325014 | USER PERFORMANCE RATING SYSTEM - A system comprises a processor-implemented collection module configured to request rating information from a first user relating to a transaction involving the first user and second user in an online transaction processing environment. The requested rating information relates to performance of the second user with respect to the transaction in a plurality of performance categories. A score generator is configured to generate a performance score relating to the second user using the rating information. A communication module is configured to communicate the performance score. | 12-23-2010 |
20110208793 | METHOD AND SYSTEM FOR MANAGING DATA TRANSACTION REQUESTS - In various embodiments, a system, method, and related computer-related medium to process data transactions are provided. In one example, a system is arranged to process data transactions in a data store including a plurality of databases. The system includes a computer interface module to receive a data transaction request from at least one requesting computer and a data access layer having one or more processors to identify at least one database in the plurality of databases. The data access layer is to define an abstraction layer between a computer interface module and the plurality of databases. | 08-25-2011 |
20130041919 | MANAGING DATA TRANSACTION REQUESTS - In various embodiments, a system, method, and related computer-readable storage medium to process data transactions are provided. In one example, a system is arranged to process data transactions in a data store including a plurality of databases. The system includes a computer interface module to receive a data transaction request from at least one requesting computer and a data access layer having one or more processors to identify at least one database in the plurality of databases.
