The following module was proposed for inclusion in the Module List: modid: Table::ParentChild DSLIP: cdhOp description: Fast and compact parent-child table lookup userid: MIKEWONG (Mike Wong) chapterid: 6 (Data_Type_Utilities) communities:
similar: rationale: Table::ParentChild implements a cross-linked list in a table with hashed headers. Given an unsigned long integer id, Table::ParentChild will tell you the unsigned long integer ids of all the parents of that item and/or all the children of the item. This works especially well with mod_perl, where your entire parent-child relationship table can be compactly held in memory for incredibly fast lookups. This module works very well with sparsely populated relationship tables. enteredby: MIKEWONG (Mike Wong) enteredon: Sat Dec 7 20:34:50 2002 GMT The resulting entry would be: Table:: ::ParentChild cdhOp Fast and compact parent-child table lookup MIKEWONG Thanks for registering, The Pause Team PS: The following links are only valid for module list maintainers: Registration form with editing capabilities: https://pause.perl.org/pause/authenquery?ACTION=add_mod&USERID=4e300000_7999639474b21845&SUBMIT_pause99_add_mod_preview=1 Immediate (one click) registration: https://pause.perl.org/pause/authenquery?ACTION=add_mod&USERID=4e300000_7999639474b21845&SUBMIT_pause99_add_mod_insertit=1
