关键词： 集装箱运输   数据仓库   ETL  

摘要： 集装箱行业目前处于快速发展阶段,但依然存在很多问题,导致各组织之间信息沟通不畅,政府部门对行业的监管和服务水平不够深入。现存的一些物流信息化平台在行业监管和信息挖掘方面相对不足,数据共享以原始数据为主。本文以宁波市集装箱行业数据管理平台的建设为例,介绍了数据仓库技术在集装箱行业监管、信息挖掘以及数据共享等方面的应用。

关键词： 城市暴雨洪涝   数据仓库   关联规则   数据挖掘  

摘要： 随着大数据技术的发展,基于大数据技术开展城市暴雨洪涝研究成为热点。根据城市防洪工作中对暴雨洪涝相关数据的业务需求,在对多源异构数据分析的基础上,设定洪水敏感性因素分析主题,构建相应的多维数据组织模式,建立城市暴雨洪涝数据仓库,有效地对城市暴雨洪涝多源异构数据进行储存、管理与组织。基于洪水敏感性因素分析主题数据仓库,利用关联规则分析进行数据挖掘,识别不同敏感性因素与洪水度量之间的关联规则,归纳出敏感性因素与洪水过程之间的关系,结果表明:将城市暴雨洪涝数据集成到数据仓库中并进行相关的数据挖掘操作,可以为防洪决策提供新的可行途径。

摘要： Background Postoperative delirium (POD) in older adults is a very serious complication. Due to the complexity of too many risk factors (RFs), an overall assessment of RFs may be needed. The aim of this study was to evaluate comprehensively the RFs of POD regardless of the organ undergoing operation, efficiently incorporating the concept of comprehensive big data using a smart clinical data warehouse (CDW). Methods We reviewed the electronic medical data of inpatients aged 65years or older who underwent major surgery between January 2010 and June 2016 at Hallym University Sacred Heart Hospital. The following six major operation types were selected: cardiac, stomach, colorectal, hip, knee, and spine. Clinical features, laboratory findings, perioperative variables, and medication history were compared between patients without POD and with POD. Results Six hundred eighty-six of 3634 patients (18.9%) developed POD. In multivariate logistic regression analysis, common, independent RFs of POD were as follows (descending order of odds ratio): operation type ([hip] OR 8.858, 95%CI 3.432-22.863; p=0.000; [knee] OR 7.492, 95%CI 2.739-20.487; p=0.000; [spine] OR 6.919, 95%CI 2.687-17.815; p=0.000; [colorectal] OR 2.037, 95%CI 0.784-5.291; p=0.144; [stomach] OR 1.500, 95%CI 0.532-4.230; p=0.443; [cardiac] reference), parkinsonism (OR 2.945, 95%CI 1.564-5.547; p=0.001), intensive care unit stay (OR 1.675, 95%CI 1.354-2.072; p=0.000), stroke history (OR 1.591, 95%CI 1.112-2.276; p=0.011), use of hypnotics and sedatives (OR 1.307, 95%CI 1.072-1.594; p=0.008), higher creatinine (OR 1.107, 95%CI 1.004-1.219; p=0.040), lower hematocrit (OR 0.910, 95%CI 0.836-0.991; p=0.031), older age (OR 1.053, 95%CI 1.037-1.069; p=0.000), and lower body mass index (OR 0.967, 95%CI 0.942-0.993; p=0.013). The use of analgesics (OR 0.644, 95%CI 0.467-0.887; p=0.007) and antihistamines/antiallergics (OR 0.764, 95%CI 0.622-0.937; p=0.010) were risk-reducing factors.

摘要： Background: Heterogeneous healthcare instance data can hardly be integrated without harmonizing its schema-level metadata. Many medical research projects and organizations use metadata repositories to edit, store and reuse data elements. However, existing metadata repositories differ regarding software implementation and have shortcomings when it comes to exchanging metadata. This work aims to define a uniform interface with a technical interlingua between the different MDR implementations in order to enable and facilitate the exchange of metadata, to query over distributed systems and to promote cooperation. To design a unified interface for multiple existing MDRs, a standardized data model must be agreed on. The ISO 11179 is an international standard for the representation of metadata, and since most MDR systems claim to be at least partially compliant, it is suitable for defining an interface thereupon. Therefore, each repository must be able to define which parts can be served and the interface must be able to handle highly linked data. GraphQL is a data access layer and defines query techniques designed to navigate easily through complex data structures. Results: We propose QL(4)MDR, an ISO 11179-3 compatible GraphQL query language. The GraphQL schema for QL(4)MDR is derived from the ISO 11179 standard and defines objects, fields, queries and mutation types. Entry points within the schema define the path through the graph to enable search functionalities, but also the exchange is promoted by mutation types, which allow creating, updating and deleting of metadata. QL(4)MDR is the foundation for the uniform interface, which is implemented in a modern web-based interface prototype. Conclusions: We have introduced a uniform query interface for metadata repositories combining the ISO 11179 standard for metadata repositories and the GraphQL query language. A reference implementation based on the existing Samply. MDR was implemented. The interface facilitates access t
