Abstract: According to a first aspect there is provided a system to automatically generate software for an object to relational mapping system. The system reads class information respectively associated with a plurality of classes. The system reads meta-data based on the class information. In addition the system automatically generates the plurality of classes based on the meta-data. The plurality of classes to be used in the object to relational mapping system to enable an application program to access data that is persistently stored in a database and accessed by the application program from an instance of a data object class that is included in the plurality of classes. The plurality of classes further includes a first class that is utilized to create the instance of the data object class.

Abstract: 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.

Abstract: 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. The data access layer is to define an abstraction layer between a computer interface module and the plurality of databases. Other embodiments are disclosed.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: According to a fourth aspect there is provided a system to receive a request to search for the data. The system performs a search of a logical table based on a single criterion to identify a plurality of rows in the logical table. The system generates a first plurality of tuples based on the plurality of rows to identify a first plurality of physical tables that are mapped to the logical table, the first plurality of tuples including a first and second tuple, the first tuple identifies a first server and a first physical table that is accessed via the first server, the second tuple identifies a second server and a second physical table that is accessed via the second server.
