摘要： 一、数据湖数据湖在学术上的定义是一种在系统或者存储库以自然格式存储的方法。它有助于存储各种模式和结构形式的数据,通常是对象块或者文件。为什么现在会提出新的自然存储格式方法?以前如何存储数据?在使用数据仓库时需调动处理大量的数据。正是因为大数据的产生,提出了数据湖的概念。

摘要： 以重庆海事局为例,根据财政部《行政事业单位内部控制规范(试行)》等相关文件,设计基于Hadoop平台的采购管理内部控制评价数据仓库体系结构,分析数据的采集、数据清洗的过程与方法,通过确定主题域、分析粒度以及概念模型、逻辑模型、物理模型的设计详细阐述了采购管理内部控制评价数据仓库的构建。最后利用HQL语言在Hive中完成对海量数据的查询分析,展示了采购管理中异常点、风险点的发现方法,以期提升行政事业单位采购管理内部控制评价的效率和质量。

关键词： 数据管理   仓库建设   供电服务   供电企业   潜在价值   国民经济   信息系统   有效管理  

摘要： 近年来我国国民经济的不断增长,社会对电力的需求不断攀升,随着5G时代的来临,万物互联已不再是梦想,供电企业面临着一个巨大的机遇与挑战——如何发挥供电企业庞大的数据价值以提高供电服务水平。目前基层仍旧存在信息系统冗余,数据量庞大,数据无法进一步穿透,底层数据不可获取,营销和运检班组流程内部各自循环,无法实现统一有效管理,数据的潜在价值无法得到发挥,供电服务和生产运行水平仍有较大的提升空间。

摘要： Application of lean process management strategies to process improvement in clinical and anatomic pathology laboratories afford opportunities to enhance workflow process to lower costs and simultaneously to improve patient safety. Bar-codes are now employed in most modern anatomic pathology laboratories to track specimens from the clinicians' office or the operating room all through the continuum of service to specimen disposal. In order to enhance patient safety and workload optimization strategies, novel computer hardware and software assets are being developed to enable monitoring, analysis, and improvement of specimen workflow and diagnostic accuracy. More recently, data warehouse technologies from the retail industry have been optimized to permit high-throughput analysis of granular data in the laboratory arena. These optimize mass-data analysis in real time in the information technology space. In this review we describe the application of an in-house designed data warehouse to the anatomic pathology assets of a large regional reference laboratory.

摘要： Background Worldwide, over 500,000 people are diagnosed with head and neck cancer each year, a disease with major impact on life expectancy and quality of life. The purpose of the Netherlands Quality of life and Biomedical Cohort study (NET-QUBIC) is to advance interdisciplinary research that aims to optimize diagnosis, treatment, and supportive care for head and neck cancer patients and their informal caregivers. Methods Using an extensive assessment protocol (electronic clinical record form, patient reported outcome measures and fieldwork (interviews and physical tests)), clinical data and data on quality of life, demographic and personal factors, psychosocial (depression, anxiety, fatigue, pain, sleep, mental adjustment to cancer, posttraumatic stress), physical (speech, swallowing, oral function, malnutrition, physical fitness, neurocognitive function, sexual function), lifestyle (physical activity, nutrition, smoking, alcohol, drugs), and social factors (social function, social support, work, health care use, and costs) are collected and stored in the data warehouse. A longitudinal biobank is built with tumor tissue, blood and blood components, saliva samples, and oral rinses. An infrastructure for fieldwork and laboratory protocols is established at all participating centers. All patients fill out patient reported outcome measures before treatment and at 3, 6, 12, 24, 36, 48, and 60 months follow-up. The interviews, physical tests and biological sample collection are at baseline and 6, 12, and 24 months follow-up. The protocol for caregivers includes blood sampling and oral rinses at baseline and a tailored list of questionnaires, administered at the same time points as the patients. In total, 739 HNC patients and 262 informal caregivers have been included in 5 out of the 8 HNC centers in the Netherlands. Discussion By granting access to researchers to the NET-QUBIC data warehouse and biobank, we enable new research lines in clinical (e.g. treatment optimizati
