Download or read book Enabling Real time Analytics on IBM z Systems Platform written by Lydia Parziale and published by IBM Redbooks. This book was released on 2016-08-08 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regarding online transaction processing (OLTP) workloads, IBM® z SystemsTM platform, with IBM DB2®, data sharing, Workload Manager (WLM), geoplex, and other high-end features, is the widely acknowledged leader. Most customers now integrate business analytics with OLTP by running, for example, scoring functions from transactional context for real-time analytics or by applying machine-learning algorithms on enterprise data that is kept on the mainframe. As a result, IBM adds investment so clients can keep the complete lifecycle for data analysis, modeling, and scoring on z Systems control in a cost-efficient way, keeping the qualities of services in availability, security, reliability that z Systems solutions offer. Because of the changed architecture and tighter integration, IBM has shown, in a customer proof-of-concept, that a particular client was able to achieve an orders-of-magnitude improvement in performance, allowing that client's data scientist to investigate the data in a more interactive process. Open technologies, such as Predictive Model Markup Language (PMML) can help customers update single components instead of being forced to replace everything at once. As a result, you have the possibility to combine your preferred tool for model generation (such as SAS Enterprise Miner or IBM SPSS® Modeler) with a different technology for model scoring (such as Zementis, a company focused on PMML scoring). IBM SPSS Modeler is a leading data mining workbench that can apply various algorithms in data preparation, cleansing, statistics, visualization, machine learning, and predictive analytics. It has over 20 years of experience and continued development, and is integrated with z Systems. With IBM DB2 Analytics Accelerator 5.1 and SPSS Modeler 17.1, the possibility exists to do the complete predictive model creation including data transformation within DB2 Analytics Accelerator. So, instead of moving the data to a distributed environment, algorithms can be pushed to the data, using cost-efficient DB2 Accelerator for the required resource-intensive operations. This IBM Redbooks® publication explains the overall z Systems architecture, how the components can be installed and customized, how the new IBM DB2 Analytics Accelerator loader can help efficient data loading for z Systems data and external data, how in-database transformation, in-database modeling, and in-transactional real-time scoring can be used, and what other related technologies are available. This book is intended for technical specialists and architects, and data scientists who want to use the technology on the z Systems platform. Most of the technologies described in this book require IBM DB2 for z/OS®. For acceleration of the data investigation, data transformation, and data modeling process, DB2 Analytics Accelerator is required. Most value can be achieved if most of the data already resides on z Systems platforms, although adding external data (like from social sources) poses no problem at all.

Download or read book Accelerating Data Transformation with IBM DB2 Analytics Accelerator for z OS written by Ute Baumbach and published by IBM Redbooks. This book was released on 2015-12-11 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transforming data from operational data models to purpose-oriented data structures has been commonplace for the last decades. Data transformations are heavily used in all types of industries to provide information to various users at different levels. Depending on individual needs, the transformed data is stored in various different systems. Sending operational data to other systems for further processing is then required, and introduces much complexity to an existing information technology (IT) infrastructure. Although maintenance of additional hardware and software is one component, potential inconsistencies and individually managed refresh cycles are others. For decades, there was no simple and efficient way to perform data transformations on the source system of operational data. With IBM® DB2® Analytics Accelerator, DB2 for z/OS is now in a unique position to complete these transformations in an efficient and well-performing way. DB2 for z/OS completes these while connecting to the same platform as for operational transactions, helping you to minimize your efforts to manage existing IT infrastructure. Real-time analytics on incoming operational transactions is another demand. Creating a comprehensive scoring model to detect specific patterns inside your data can easily require multiple iterations and multiple hours to complete. By enabling a first set of analytical functionality in DB2 Analytics Accelerator, those dedicated mining algorithms can now be run on an accelerator to efficiently perform these modeling tasks. Given the speed of query processing on an accelerator, these modeling tasks can now be performed much quicker compared to traditional relational database management systems. This speed enables you to keep your scoring algorithms more up-to-date, and ultimately adapt more quickly to constantly changing customer behaviors. This IBM Redbooks® publication describes the new table type that is introduced with DB2 Analytics Accelerator V4.1 PTF5 that enables more efficient data transformations. These tables are called accelerator-only tables, and can exist on an accelerator only. The tables benefit from the accelerator performance characteristics, while maintaining access through existing DB2 for z/OS application programming interfaces (APIs). Additionally, we describe the newly introduced analytical capabilities with DB2 Analytics Accelerator V5.1, putting you in the position to efficiently perform data modeling for online analytical requirements in your DB2 for z/OS environment. This book is intended for technical decision-makers who want to get a broad understanding about the analytical capabilities and accelerator-only tables of DB2 Analytics Accelerator. In addition, you learn about how these capabilities can be used to accelerate in-database transformations and in-database analytics in various environments and scenarios, including the following scenarios: Multi-step processing and reporting in IBM DB2 Query Management FacilityTM, IBM Campaign, or Microstrategy environments In-database transformations using IBM InfoSphere® DataStage® Ad hoc data analysis for data scientists In-database analytics using IBM SPSS® Modeler

Download or read book Guidelines for Constructing Consumption Aggregates for Welfare Analysis written by Angus Deaton and published by World Bank Publications. This book was released on 2002-01-01 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: In September 2001, staff from the World Bank and the International Monetary Fund met with the objective of strengthening collaboration between the two organizations in projects of civil service reform. This strengthened collaboration will have key benefits in ensuring consistency between the conflicting goals of the two organizations, establishing realistic objectives within the reform process, and maintaining a core set of wage and employment data. The principal conclusion arrived at was that World Bank and IMF staff should be engaging in collaboration earlier in the reform process. To guide the collaboration, six foundations were identified. These include: develop a medium-term fiscal framework; foster national ownership by making reforms politically feasible; focus and streamline conditionality; agree on sequencing and timing of reforms; and strengthen data collection. These principals will be tested for effectiveness in several focus countries.

Download or read book Thirty Years with Stata written by Enrique Pinzon and published by Stata Press. This book was released on 2015-07-30 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a sometimes serious and sometimes whimsical retrospective of Stata, its development, and its use over the last 30 years. The view from the inside opens with an essay by Bill Gould, Stata's president and cofounder, that discusses the challenges and concepts that guided the design and implementation of Stata. This is followed by an interview of Bill by Joe Newton that discusses Bill's early interest in computing, his early work on a program for matching prom dates in the days when you had to purchase time on computers, and further exploration of the guiding principles behind Stata. Finally, Sean Becketti, Stata's first employee, delves into the not-to-be-missed culture of Stata in its infancy. The view from the outside comprises 14 essays by prominent researchers and members of the Stata community. Most discuss Stata's use and evolution in disciplines such as behavioral sciences, business, economics, epidemiology, time series, political science, public health, public policy, veterinary epidemiology, and statistics. Some take a sweeping overview. Others are more intimate personal recollections. Mostly, we simply wanted to celebrate the relationship between Stata users and Stata software. We hope that this volume holds something interesting for everyone.

Download or read book DB2 10 for z OS Performance Topics written by Paolo Bruni and published by IBM Redbooks. This book was released on 2013-08-23 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: DB2® 10 for z/OS can reduce the total DB2 CPU demand from 5-20%, compared to DB2 9, when you take advantage of all the enhancements. Many CPU reductions are built in directly to DB2, requiring no application changes. Some enhancements are implemented through normal DB2 activities through rebinding, restructuring database definitions, improving applications, and utility processing. The CPU demand reduction features have the potential to provide significant total cost of ownership savings based on the application mix and transaction types. Improvements in optimization reduce costs by processing SQL automatically with more efficient data access paths. Improvements through a range-list index scan access method, list prefetch for IN-list, more parallelism for select and index insert processing, better work file usage, better record identifier (RID) pool overflow management, improved sequential detection, faster log I/O, access path certainty evaluation for static SQL, and improved distributed data facility (DDF) transaction flow all provide more efficiency without changes to applications. These enhancements can reduce total CPU enterprise costs because of improved efficiency in the DB2 10 for z/OS. DB2 10 includes numerous performance enhancements for Large Objects (LOBs) that save disk space for small LOBs and that provide dramatically better performance for LOB retrieval, inserts, load, and import/export using DB2 utilities. DB210 can also more effectively REORG partitions that contain LOBs. This IBM Redbooks® publication® provides an overview of the performance impact of DB2 10 for z/OS discussing the overall performance and possible impacts when moving from version to version. We include performance measurements that were made in the laboratory and provide some estimates. Keep in mind that your results are likely to vary, as the conditions and work will differ. In this book, we assume that you are somewhat familiar with DB2 10 for z/OS. See DB2 10 for z/OS Technical Overview, SG24-7892-00, for an introduction to the new functions.

Download or read book Emergent Public Health Issues in the US Mexico Border Region written by Cecilia Ballesteros Rosales and published by Frontiers Media SA. This book was released on 2017-02-16 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: US-Mexico border region area has unique social, demographic and policy forces at work that shape the health of its residents as well as serves as a microcosm of migration health challenges facing an increasingly mobile and globalized world. This region reflects the largest migratory flow between any two nations in the world. Data from the Pew Research Center shows over the last 25 years there has never been lower than 140,000 annual immigrants from Mexico to the United States (with peaks over 700,000). This migratory route is extremely hazardous due to natural (e.g., arid and hot desert regions) and human made barriers as well as border enforcement practices tied to socio-political and geopolitical pressures. Also, reflecting the national interdependency of public health and human services needs, during the most recent five year period surveyed the migratory flow between the US and Mexico has equaled that of the flow of Mexico to the US--both around 1.4 million persons. Of particular public health concern, within the US-Mexico region of both nations there is among the highest disparities in income, education, infrastructure and access to health care--factors within the World Health Organization’s conceptualization of the Social Determinants of Health, and among the highest rates of chronic disease. For instance obesity and diabetes rates in this region are among the highest of those monitored in the world, with adult population estimates of the former over 40% and estimates in some population sub-groups for the latter over 20%. The publications reflected in this Research Topic, all reviewed from experts in the field, addressed many of the public health issues in the US Mexico Border Health Commission’s Healthy Border 2020 objectives. Those objectives-- broad public health goals used to guide a diverse range of government, research and community-based stakeholders--include Non Communicable Diseases (including adult and childhood obesity-related ones; cancer), Infectious Diseases (e.g., tuberculosis; HIV; emerging diseases--particularly mosquito borne illnesses), Maternal and Child Health, Mental Health Disorders, and Motor Vehicle Accidents. Other relevant public health issues affecting this region, for example environmental health, binational health services coordination (e.g., immunization), the impact of migration throughout the Americas and globally in this region, health issues related to the physical climate, access to quality health care, discrimination/mistreatment and well-being, acculturative/immigration stress, violence, substance use/abuse, oral health, respiratory disease, and well-being from a social determinants of health framework, are critical areas addressed in these publications or for future research. Each of these Research Topic publications presented applied solutions (e.g., new programs, technology or infrastructure) and/or public health policy recommendations relevant to each public health challenge addressed.
