Bulk traversal of large data structures
View Patent ↗A PDM system, method, and computer program product for traversing a large data structure including corresponding runtime objects. A method includes receiving traversal parameters including a plurality of unique object identifiers (UIDs) corresponding to objects in a data structure. The method includes receiving input objects, including input runtime objects, and closure rule clauses. The method includes configuring runtime objects, from the objects in the data structure, according to the traversal parameters, and storing the runtime objects in a temporary table. The method includes traversing the data structure and temporary table using the closure rules to produce traversed objects, and serializing and storing the traversed objects.
1. A method performed by a product data management (PDM) data processing system, comprising:
receiving traversal parameters including a plurality of unique object identifiers (UIDs) corresponding to objects in a data structure;
receiving input objects, including input runtime objects, and closure rule clauses;
configuring runtime objects, from the objects in the data structure, according to the traversal parameters;
storing the runtime objects in a temporary table;
constructing database queries corresponding to the closure rule clauses;
executing the database queries on the data structure and the temporary table;
traversing the data structure and the temporary table using the closure rules to produce traversed objects; and
serializing and storing the traversed objects.
2. The method of claim 1 , wherein the traversal parameters include configuration parameters defining runtime objects.
3. The method of claim 1 , wherein the data structure is a bill of materials (BOM) structure, and the runtime objects are BOMLines.
4. The method of claim 1 , wherein the PDM data processing system groups the UIDs by associated real classes.
5. The method of claim 4 , wherein the PDM data processing system determines UIDs to be input for each group and associated closure rule clauses.
6. The method of claim 1 , wherein the PDM data processing system also evaluates process-only closure rule clauses.
7. A product data management (PDM) data processing system comprising a processor and accessible memory, the data processing system particularly configured to:
