Patent number: 8301590Abstract: Methods and systems are presented for custom caching. Application threads define caches. The caches may be accessed through multiple index keys, which are mapped to multiple application thread-defined keys. Methods provide for the each index key and each application thread-defined key to be symmetrical. The index keys are used for loading data from one or more data sources into the cache stores on behalf of the application threads. Application threads access the data from the cache store by providing references to the caches and the application-supplied keys. Some data associated with some caches may be shared from the cache store by multiple application threads. Additionally, some caches are exclusively accessed by specific application threads.Type: GrantFiled: February 14, 2011Date of Patent: October 30, 2012Assignee: eBay Inc.Inventors: Christopher J. Kasten, Greg Seitz

Patent number: 8291376Abstract: According to a second aspect there is provided a method and system to automatically regenerate software for an object to relational mapping system. The system automatically regenerates a first set of classes. For each class, the system reads class information; reads meta-data based on the class information; and automatically regenerates the class based on the meta-data without overwriting associated custom code. The first set of classes includes base code that is associated with the custom code. The first set of classes and the base code are utilized by the object to relational mapping system to enable access to data that is persistently stored in a database.Type: GrantFiled: December 15, 2009Date of Patent: October 16, 2012Assignee: eBay Inc.Inventors: Greg Seitz, Christopher J.

Publication number: 20120221599Abstract: According to a fourth aspect there is provided a system to receive a request to search for data. The system performs a search of a logical table based on a criterion to identify a plurality of rows in the logical table. The system generates fetch levels including a first and second plurality of tuples based on the plurality of rows. Each fetch level includes a plurality of tuples that identify servers and physical tables that may store the data. The system further queries at least two data sources for the data based on the first plurality of tuples and communicates the data.Type: ApplicationFiled: May 3, 2012Publication date: August 30, 2012Applicant: eBay Inc.Inventors: Greg Seitz, Christopher J.

Publication number: 20120179720Abstract: A system to automatically generate query language in software is described. The system receives a request for data that is persistently stored in a database. The system selects a predefined query template from a number of query templates based on the request. The system utilizes the query template to receive content from at least one different source, the first source being a prototype data object. The system generates a query statement based on the query template that includes the content. Finally the system queries the database using the query statement to retrieve the requested data.Type: ApplicationFiled: March 20, 2012Publication date: July 12, 2012Applicant: eBay Inc.Inventors: Greg Seitz, Christopher J.

Patent number: 7941469Abstract: 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.Type: GrantFiled: December 14, 2009Date of Patent: May 10, 2011Assignee: eBay Inc.Inventors: Elena Grossfeld, Surjatini Widjojo, Thorsten Lockert, Greg Seitz, Kenneth Randall Wigginton, Christopher J.

Patent number: 7650338Abstract: A method and system is provided to process data transactions in a data store including a plurality of databases. The system may comprise a computer interface module to receive a data transaction request from at least one requesting computer and a data store interface module to interface the system to the plurality of databases. The system also includes a data access layer defining an abstraction layer to identify at least one database of the plurality of databases. The data transaction request may be an object orientated request and the plurality of databases may be horizontally distributed wherein the data access layer defines an object orientated abstraction layer between the computer interface module and the plurality of databases.
