【摘要】：越来越多的商家选择在各个电子商务网站上设立网络店铺,需要一个管理平台为其提供统一的接口,来进行订单审核和发货等操作。传统大型ERP (企业资源计划)企业提供的产品由于其体系架构过于庞大复杂,往往会存在系统响应慢、处理效率低的问题,不能满足电子商务管理需求;而新出现的一些专门针对网络店铺的各类小型管理系统由于设计不完善,存在着不能为较大订单量的商户提供快速高效服务的缺陷。论文针对电子商务中数据库并行操作频繁导致的冲突和数据不一致、海量数据分页显示慢等问题,开展数据库操作一致性保证、分页显示优化、电子商务操作性能对比实验等研究。主要工作包括:(1)针对系统中频繁进行的分页显示操作,提出了评价各种分页方法优劣的度量指标,基于这些指标对几种常见的分页方法进行了分析和比较,最后提出了一种在各个度量指标上均表现优秀的基于等值联接的分页查询方法。(2)根据系统的应用场景,建立了基于读写分离的数据加速访问模型,并将此模型应用于订单的查询与审核以及销量的展示操作中。对于读写分离情形下的数据同步问题,提出两阶段检查的方案来保证数据的一致性。(3)基于前述的优化策略,实现电子商务管理平台,提供订单审核、最优策略发货、电子运单生成、销量展示等实用功能。通过利用实际的订单数据进行性能测试,分别证实了基于等值联接的分页方法以及基于读写分离的数据访问模型能够在大规模数据的处理中带来显著的性能提升,使得系统在数据规模较大的情况下,仍能提供高性能、低延时的服务,因此基于此策略实现的管理平台能够满足网络店铺商家的需求,具有较高的实用价值和较好的应用前景。
[Abstract]:More and more businesses choose to set up online stores on various e-commerce websites, and need a management platform to provide a unified interface for order audit and delivery operations. The products provided by traditional ERP (Enterprise Resource Planning) enterprises often have the problems of slow system response and low processing efficiency because of their large and complex architecture, which can not meet the requirements of e-commerce management. However, some new small management systems, which are specially designed for the network stores, have the defects of not being able to provide fast and efficient service for the merchants with large order volume because of their imperfect design. Aiming at the conflicts and data inconsistency caused by the frequent parallel operation of database in electronic commerce and the slow pagination of massive data, this paper develops the consistency of database operation and the optimization of paging display. E-commerce operation performance contrast experiment and so on. The main work includes: (1) aiming at the frequent paging display operations in the system, the paper puts forward the metrics to evaluate the advantages and disadvantages of various paging methods, and analyzes and compares several common paging methods based on these indexes. Finally, an excellent paging query method based on equivalent join is proposed. According to the application scenario of the system, a data accelerated access model based on the separation of reading and writing is established. The model is applied to the query and audit of orders and the display of sales volume. For the problem of data synchronization in the case of separation of reading and writing, a two-stage checking scheme is proposed to ensure the consistency of data. Based on the above optimization strategy, the E-commerce management platform is implemented to provide order audit and optimal policy delivery. Electronic waybill generation, sales display and other practical functions. By using the actual order data for performance testing, it is proved that the paging method based on equivalent join and the data access model based on read and write separation can bring about significant performance improvement in large-scale data processing. So the management platform based on this strategy can meet the needs of network store merchants and has higher practical value and better application prospect.
