14. JAVA vs. PERL TK Object-Oriented –Code & Data merged into indivisible object –More power and flexibility of object [class, instance, inheritance, polymorphism] –Intelligent information request; messages >> object’s interface Speed: Sufficient Memory: Large but Affordable Interface: Very Good JavaPerl TK Procedural-Oriented –Code & Data kept separately –Functions sequentially [change in code affects what follows] –Code reusable Speed: Good Memory: Small Interface: Basic Structure :: Performance :: HBD HV Control System – Development Manuel Proissl Page 14 of 18 Upgrades For Run8 | PHENIX, BNL HBD Meeting :: September 18 th, 2007

15. JAVA vs. PERL TK Error Analysis: Easy –Problems, errors, malfunctions easy to detect/track + control Protection: Safe –Prevents dead loops, memory leaks –Source code secure [compiler] GUI :: incl. SSH networking: very good JavaPerl TK Error Analysis: Difficult Protection: Bad –memory leaks >> no functions available –Source code not safe [not designed to] GUI :: TK package SSH networking: 3 rd party libraries Robust :: Function :: HBD HV Control System – Development Manuel Proissl Page 15 of 18 Upgrades For Run8 | PHENIX, BNL HBD Meeting :: September 18 th, 2007
