随着移动设备的普及，二维条码得到了广泛的应用，其主要是用于文本信息的存储，而对图像、声音和视频的存储是少之又少。用二维条码存储图像、声音和视频等信息会比文本存储的内容更加丰富、更加直观。但随之而来的是海量数据的产生，而怎样对数据进行采集，然后在后端对数据进行高效的存储和操作是当今的热点问题。论文在对数据采集的基础上，研究如何高效地进行存储和交互数据。%With the popularity of mobile devices ,QR bar code has been widely used ,which is mainly used for text in‐formation storage ,but very limitedly for images ,audios and videos .Using QR bar code store images ,audios and videos , which will be much more plentiful and intuitive than the text ,will produce massive amounts of date .So ,the current hot is‐sue is how to collect data and then to handle and store them efficiently in the back‐end .This article is a study of efficient data storage and interaction based on the data collection .
