The Design And Implementation Of Picture Management System Background

With the widely used of Internet technology, every individual and organization involved in the Internet can become one source of information, to produce all kinds of information and data on different kinds of carriers. At the same time, these individuals and organizations can also become information relays to process and forward information.The large number of nodes and links make the explosive growth of the Internet data, the crazy expansion of data scale, and the increase of data structure diversity. As the most common type of information on the Internet, the picture is a kind of unstructured data attached with some other structured information, which makes picture information own large quantity and complex diversity. The big data has brought new challenges to the traditional picture management system. Traditional relational database owns solid mathematical theory, high application rate and reliability, but lacks the ability to deal with large-scale data retrieval. Full text retrieval can be used to deal with large-scale data retrieval. It is meaningful to introduce full text retrieval technology into picture management system.Picture :management system development work is divided into two parts: front-end develop and background develop. Front-end developer is in charge of the developing of user interface, request receiving, form information validating and response content displaying. Background work include business data processing, specific functions implementation,database access, response returning. This thesis gives the design and implementation of one kind of picture management system. This system includes three modules: user module, picture module and log module.In order to improve the utilization efficiency of picture information,the picture management sub module adds structure information to picture files so that picture files can be searched in the system. This thesis designs and implements functions of user management, picture upload and download, picture information management, log recording and sorting.In order to improve the search efficiency, the picture search sub module combines the MySQL and Elasticsearch search technology,extends the custom relational database search technology, to propose a joint search scheme for a large number of picture data, which not only ensures the reliability and security of picture information operation, but also improves the performance of picture information search ability.
