i've been working on improving ticket system made sometime ago , don't know best way store ticket updates. background- each ticket can updated text, status can updated , can assigned other people. the tickets table looks this: tickets: |tk_id|tk_status|tk_opened_by|tk_assigned|tk_room|tk_problem|tk_date|tk_time| |-----|---------|------------|-----------|-------|----------|-------|-------| currently when ticket updated (either comment, status change or assignment) different tables used this. follows: tk_update: |update_id|tk_id|user_id|comment|date|time| |---------|-----|-------|-------|----|----| tk_status: |status_update_id|tk_id|user_id|status|comment|date|time| |----------------|-----|-------|------|-------|----|----| tk_assign: |assign_id|tk_id|user_id|assigned_to|comment|date|time| |---------|-----|-------|-----------|-------|----|----| this current set means pulling data 3 tables ticket , ordering them before displaying data on webpage. i'm think

i have coded splay tree. nodes represented this. struct node{ node *l; /// left node node *r; /// right node int v; /// value }; now, need know summation of numbers in tree within range. this, implemented following function named summation. void summation(node *r, int st, int ed) { if(!r) return; if(r->v < st){ /// should not call left side summation(r->r, st, ed); } else if(r->v > ed){ /// should not call right side summation(r->l, st, ed); } else{ /// should call both side ret+=r->v; summation(r->l, st, ed); summation(r->r, st, ed); } return; } ret global int variable initialized 0 before calling summation function. 2 parameters st & ed defines range (inclusive). the summation function works @ complexity of o(n). can suggest faster implementation this?? this splay tree implementation did time ago , tested agains

i've created chained select-boxes dynamically json data receive server. chaining/cascading works in way every select-box named object following properties: parent attribute: name of object parent of select-box object. options: array of option objects, each object contains: (a) option value (b) parent option value - parent select-box value current value mapped.
