Dear Folks, I have to draw class diagram and am very new to this topic. Example, There are 2 classes named class1, class2. class1 is a singleton class and class2 as normal classes. class2 accessing the api of class1 using scope. so what is the notation we have to give between class1 and class2? is that composition or aggregatiorn or any other? Thanks in advance -Selva
