Visualization of Mappings Between Schemas George G. Robertson Mary P. Czerwinski John E. Churchill George Robertson Overview • Scalable interface for examining connections between two sets of hierarchical data The Problem The Solution(s) • Highlight Propagation • Auto-Scrolling • Coalescing Trees • Multi-Select • Incremental Search Highlight Propagation Auto-Scrolling • Auto-scroll map – Center mappings on selected element • Auto-scroll columns within map – Map consists of columns of functoids • “functoids” is not a word in Word™ • Auto-scroll other schema tree view – Animated transition Auto-Scrolling Coalescing Trees Multi-Select Incremental Search User Study • 8 very experienced BizTalk users • 4 Versions – A: Baseline – B: Add highlight propagation – C: Add auto-scroll – D: Add coalescing and search ticks • (i.e., everything) • 6 isomorphic tasks / person / version • Order controlled by partial Latin Square Results Results Results • Time Trials – All significantly faster than baseline – Full feature set (D) faster than just highlighting (B) • Satisfaction Survey – All preferred over baseline – No significant difference between B, C, D • However, unanimously preferred D when asked directly (people like features!) Future Work • Extend features to editing scenario • Include features in TreeView control – Animated scrolling – Coalescing – Incremental search with scrollbar ticks Discussion • Does reordering versions even matter when they’re incremental improvements? – Might get more useful data by separating features • Generalize these ideas to other problems?
