Art Carpenter demystifies the powerful REPORT procedure and shows you how to incorporate this highly flexible and customizable procedure into your SAS reporting programs. Combining his years of SAS experience with a talent for instruction, Art offers clear and comprehensive coverage that demonstrates how valuable this procedure is for both summarizing and displaying data. Illustrated with more than two hundred examples and sample exercises to reinforce your learning, Carpenter's Complete Guide to the SAS REPORT Procedure provides you with information that you can put to immediate use. The text is divided into three distinct sections. Part 1 introduces you to PROC REPORT, showing you how it works and "thinks." This section is designed to be read linearly by users who are unfamiliar with the procedure. Part 2 is a collection of increasingly more complex examples that feature advanced options and capabilities. It also introduces the relationship between PROC REPORT and the Output Delivery System (ODS). Part 3 incorporates the options and statements described in Parts 1 and 2 into a series of examples that highlight many of the extended capabilities of PROC REPORT. Included in this section is a discussion of a few ODS statements and options that might be useful to a PROC REPORT programmer, plus an in-depth look at the PROC REPORT process itself, especially as it relates to the execution of compute blocks. Art's author page at support.sas.com/carpenter includes the following bonus material: example SAS data sets, example results, and a compilation of nearly 100 related conference papers.

Computation and Storage in the Cloud is the first comprehensive and systematic work investigating the issue of computation and storage trade-off in the cloud in order to reduce the overall application cost. Scientific applications are usually computation and data intensive, where complex computation tasks take a long time for execution and the generated datasets are often terabytes or petabytes in size. Storing valuable generated application datasets can save their regeneration cost when they are reused, not to mention the waiting time caused by regeneration. However, the large size of the scientific datasets is a big challenge for their storage. By proposing innovative concepts, theorems and algorithms, this book will help bring the cost down dramatically for both cloud users and service providers to run computation and data intensive scientific applications in the cloud. Covers cost models and benchmarking that explain the necessary tradeoffs for both cloud providers and users Describes several novel strategies for storing application datasets in the cloud Includes real-world case studies of scientific research applications Covers cost models and benchmarking that explain the necessary tradeoffs for both cloud providers and users Describes several novel strategies for storing application datasets in the cloud Includes real-world case studies of scientific research applications

This IBM® Redbooks® publication describes how the IBM Content Collector family of products can help companies to create value-based archiving solutions. IBM Content Collector provides enterprise-wide content archiving and retention management capabilities. It also provides IT administrators with a high level of control over the archiving environment. From a common interface, organizations can implement policies that define what gets archived from which source system, make decisions about how content gets archived based on the content or metadata of the information, and determine the retention and governance rules associated with that type of content. Content Collector enables IT staff to implement granular archiving policies to collect and archive specific pieces of information. IBM Content Collector helps with the following tasks: Eliminating point solutions and lowering costs with a unified collection, management, and governance approach that works effectively across a broad range of source systems and information types Appraising, improving understanding of, culling, and properly selecting the information to archive Retaining, holding, and disposing of archived content efficiently and defensibly Eliminating the costs and risks inherent with over-retention This book covers the basic concepts of the IBM Content Collector product family. It presents an overview explaining how it provides value-based archiving and a defensible disposal capability in the archiving solutions. With the integration of IBM Content Classification and IBM Enterprise Records, the book also explains and showcases how these products can be used to add more flexibility, power, and capabilities to archiving solutions. The book is intended for IT architects and solution designers who need to understand and use IBM Content Collector for archiving solution implementations.
