The diagram illustrates the instantiation of key classes within an e-commerce system, specifically highlighting the relationships between the Shop, individual Book objects, the ShoppingCart, and the resulting Order. Key data points captured include specific book attributes like titles, pricing, and stock levels, as well as transaction details such as order date, delivery address, payment method, and total amount. This visual model provides a clear snapshot of an object-oriented system state, demonstrating how class structures translate into actual runtime instances for order processing and inventory management within a web-based retail environment. It serves as an instructional resource for understanding object instances and their interactions within a typical software design pattern.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":30,"@type":76,"position":81},"https://docshare.wps.com/document/technology/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/uml-object-diagram-online-shop/655928/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/uml-object-diagram-online-shop/655928.png","ImageObject",300,407,{"name":92,"@type":93},"Tirek","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-30","2026-10-25",true,{"@type":102,"interactionType":103,"userInteractionCount":8},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What does the UML object diagram represent?","Question",{"text":112,"@type":113},"The diagram depicts a concrete instance of an online shop system, specifically 'Books4Sale', showing how objects like Books, a ShoppingCart, and an Order interact.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"Which specific book titles are currently displayed in the diagram?",{"text":117,"@type":113},"The books included are Brave New World, Animal Farm, The Old Man and the Sea, and 1984.",{"name":119,"@type":110,"acceptedAnswer":120},"What are the details of the processed order?",{"text":121,"@type":113},"The order occurred on 19/01/2016, is marked as 'Paid', was shipped to 10 Downing Street, and utilized Mastercard for payment.","https://schema.org",{"og:url":83,"og:type":124,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":126,"canonical":83},"index,follow",{"doc_id":128,"site_id":62},655928,1792964984,{"code":4,"msg":5,"data":131},{"doc_id":128,"user_id":132,"nickname":92,"user_avatar":133,"doc_module":4,"category_id":29,"category_name":30,"doc_title":65,"doc_description":67,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":8,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":8,"language":139,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":67,"update_tm":129,"read_time":81},5909896572756,"https://ap-avatar.wpscdn.com/davatar_155a257f0dc6eb9ab79c44ca47cae57d","# Object Diagram","cbCainplMK2xSAxO","https://ap.wps.com/l/cbCainplMK2xSAxO","pdf",199746,"English","# Online Shop Structure\n## Class Instances and Relationships\n## Shopping Cart and Order Data","[{\"question\":\"What does the UML object diagram represent?\",\"answer\":\"The diagram depicts a concrete instance of an online shop system, specifically 'Books4Sale', showing how objects like Books, a ShoppingCart, and an Order interact.\"},{\"question\":\"Which specific book titles are currently displayed in the diagram?\",\"answer\":\"The books included are Brave New World, Animal Farm, The Old Man and the Sea, and 1984.\"},{\"question\":\"What are the details of the processed order?\",\"answer\":\"The order occurred on 19/01/2016, is marked as 'Paid', was shipped to 10 Downing Street, and utilized Mastercard for payment.\"}]","UML Object Diagram - Online Shop | PDF"]
