项目介绍
随着计算机与互联网的普及,人们的网上生活日益丰富,消费方式也在改变。电商成为人们日常消费的一个重要组成部分,所占的比重也越来越高。与此同时宠物也逐渐进入人们的家庭并扮演着越来越重的角色,成为养宠人日常生活中不可分割的一部分。由于养宠观念的变化,宠物及其商品的需求越来越大,同时宠物商品品种多、范围广,人们也乐忠于为自己的爱宠消费,宠物经济便越来越受人关注。
线上宠物商店打破了时间的限制和地域的隔阂,降低了管理成本及风险,拓宽了销售路径和客户群,使交易变得高效而便捷。本系统不仅方便了买卖双方的交易,同时也促进了宠物市场上网消费,一定程度上拉动了互联网经济的发展,因此它的发展是一种必然趋势。
