Abstract
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.
