摘要： A many-to-many relationship management system. In an object persistence management system, a many-to-many relationship manager can include one or more related objects; a junction table storing relationships between the related objects; and, one or more corresponding links. Each link can correspond to one of the objects. Furthermore, each link can persist state information for the corresponding object in an associated object table. Finally, each link can manage the junction table responsive to changing relationships with others of the related objects. Importantly, as the present invention distributes the management of the junction table, a counter-operation management protocol can be provided which can resolve conflicts which arise in the management of the junction table in response to changing relationships among their associated objects.

摘要： A technique for managing life cycles of objects which are created by mapping layer software in response to retrieving data from a relational database. Object-level cursors are defined, where an object cursor is mapped to a database cursor for a particular cursored query. When the application traverses from one root object to another, the object-level cursor is advanced and memory used to store the objects corresponding to the previous subset of cursored rows is released, freeing memory space for a next set of objects corresponding to a next subset of cursored rows. The database cursor is also advanced to align with a row corresponding to the current root object to be processed by the application. Using this technique, result sets may be arbitrarily large without impacting system performance or efficiency.

摘要： A technique for using working set hints and query signatures to optimize the selection and execution of fixed, static services or queries of information from a database, object server, or similar data repository. The working set hints describe how to read ahead when doing a database query, in order to retrieve data in a single database access that a task is likely to need as it continues executing. By storing the working set hints externally from the application code, the hints can be modified as experience is gained about the true working set that is required during use of each task without having to modify and recompile the application itself. Signatures are created and associated with query commands or services. These signatures are compared to the working set hints for a task when the task traverses an association and needs to retrieve data from the data repository. The signature which best matches the task's working set hints is automatically selected, and the query or service associated with this signature is then executed, providing an optimized database retrieval operation.
摘要翻译：使用工作集提示和查询签名来优化来自数据库，对象服务器或类似数据存储库的固定，静态服务或信息查询的选择和执行的技术。工作集提示描述了在执行数据库查询时如何阅读前提，以便在单个数据库中检索数据库访问任务在继续执行时可能需要的数据。通过从应用程序代码外部存储工作集提示，可以修改提示，以便在使用每个任务期间所需的真实工作集获得经验，而无需修改和重新编译应用程序本身。签名被创建并与查询命令或服务相关联。当任务遍历关联并需要从数据存储库检索数据时，将这些签名与任务的工作集提示进行比较。自动选择与任务的工作集提示最匹配的签名，然后执行与该签名相关联的查询或服务，从而提供优化的数据库检索操作。
