Arrows represent Dependencies, and demonstrate the sequencing of the diagram; in this example, Activity C cannot begin until both Activity A and Activity B have been completed, and Activity D cannot begin until Activity C has been completed. <> The applicant hands a filled out copy of Enrollment Form. While Petri net based approach is useful and interesting, it does not exploit the underlying inherent reactive behaviour of activity diagrams. These diagrams describe the actual state of activities of a system by showing all the sequence of activities performed. A role activity diagram is a high-level visual notation with an object-oriented flavour for modelling the dynamics and role structure of an organisation. ��e aTe����f��d��#�R^��jF-���9���C G��1��TN��S>�FnW�3�lɭ��b6%������S�N�qW�M�l���&�i�R�V��FW���8=�S�D�� Ԩ�� Y�1'私��"�_h��t�H�U�gT�t�ކ���nKSŊҮ���Y���4��e�n�EW��:'h���.>*xrv��ݠ&���n�N"A�Ag����¢lefn��s誆�bѭslTU3�]M�lꙀf*Wӡ�i9�s�L/�]� u!��!���r�2�N[*�QUq�W�K7��QHţ��i�@������1�� b �����CT ��T�T1�W@%���@��dRR6�IC�3 �n������9X��;�p�Aʐ&�B�r��!_(��b�HI�Bh;T �@�P����A��5��-4-@?Coa&�tXփM`�����8΀��Rx\��'�x�߇g���2�@X�!|��D�Ld+R��!�H/2�L!_#3�"�Ţ4��rQ{� A�h��B��� :�~�΢K���1��a�pL&S���tb�b&1�1�WX,��ecm�^�l� [�=��Î`�`��8Ng�s���bqٸ2\��2�.n�O�k����H�_���w�/�������;�?
