Pro ODP.NET for Oracle Database 11g (Expert's Voice in Oracle) ReviewOverall the book has some very good examples and explanations. The introduction is very good as well. However, there are a bit too many redundant examples that seem to make the book thicker unnessarily. That being said, sometimes the detailed examples were very helpful.Pro ODP.NET for Oracle Database 11g (Expert's Voice in Oracle) OverviewPro ODP.NET for Oracle Database 11g is the "go to" book for .NET programmers wanting to use the Oracle Database.

Complete Web Monitoring: Watching Your Visitors, Performance, Communities, and Competitors ReviewThis book will change the way you think about your online business. From page performance, to conversions, to user experience, to social media, "Complete Web Monitoring" covers the gamut of tools, techniques, and services that exist today to help you truly optimize the success of your online business.
The book breaks down all online business into four categories: Media, Transaction, Collaboration, and SaaS. Throughout the book, as you learn about the various flavors of analytics, usability, surveys, page performance, monitoring, online community management, collaboration...and how all of this fits together...you are given specific, direct, and actionable steps to take that apply to your specific business model. For example, "Transaction" businesses must focus on conversions, uptime of the checkout process, and what customers are saying about their products. "SaaS" companies should focus on the performance of their most common paths through the application, popularity of specific features, and the user experience of the holistic product.
The amount of data and the number of tools at your disposal are overwhelming. At times this book is rather overwhelming. Choosing between an analytics provider, a monitoring service, or a social media tracking service could keep you from actually accomplishing real work. Sometimes too much choice and too much data is a very dangerous thing. It's important to remember to step back, remember the goals behind your measurements, and focus on solving the problems of your customers. With that in mind, the lessons learned in this book will help you zero in on optimizing those end goals.
"Complete Web Monitoring" is valuable for the same reason it is difficult to categorize. The various tools and services that you learn about are generally used by many different departments across an organization, all for very different reasons, generally without any sort of collaboration. What you realize reading this book is that there is a lot more to the success of your business than the limited visibility you get from using these tools independently. To truly understand how your business is doing, and how you can improve not only revenue but also how you build your business, you need a holistic picture that includes data from numerous sources. "Complete Web Monitoring" gives you more then anything I've come across previously in giving you the tools, pointing you to the techniques, and teaching you to focus on what is most important.Complete Web Monitoring: Watching Your Visitors, Performance, Communities, and Competitors Overview
Do you really understand your online presence? Are you confident that visitors can use your website? Do you know their motivations? How do online communities perceive your company? To innovate and adapt your business quickly, you must know the answers to these questions.Complete Web Monitoring demonstrates how to measure every aspect of your web presence -- including analytics, backend performance, usability, communities, customer feedback, and competitive analysis -- whether you're running an e-commerce site, a community, a media property, or a Software-as-a-Service company. This book's concrete examples, clear explanations, and practical recommendations make it essential for anyone who runs a website. With this book you will:



Discover how visitors use and interact with your site through web analytics, segmentation, conversions, and user interaction analysis
Find out your market's motivations with voice-of-the-customer research
Measure the health and availability of your website with synthetic testing and real-user monitoring
Track communities related to your online presence, including social networks, forums, blogs, microblogs, wikis, and social news aggregators
Understand how to assemble this data into clear reports tailored to your organization and audience

You can't fix what you don't measure. Complete Web Monitoring shows you how to transform missed opportunities, frustrated users, and spiraling costs into online success. "This is a very comprehensive view of just about everything one needs to know about how websites work and what one needs to know about them. I'd like to make this book required reading for every employee at Gomez." -- Imad Mouline, CTO of Gomez

The Art of Application Performance Testing: Help for Programmers and Quality Assurance ReviewThis well-written primer provides just enough information to help one get started with automated performance testing. It outlines several recommended practices to automating performance testing (e.g., user activity recording, deploying software monitors, etc) and describes how some of them were put to use in two case studies and how they helped in root cause analyses. It discusses desirable capabilities to look for in performance testing tools and only briefly mentions special considerations for technologically complex applications such as those that use AJAX, SAP, or Citrix, for example. A more in-depth discussion of those considerations and how to address them would have been really useful. Although information on select tool vendors and the type of tool offerings they provide is included, there is no additional description of any of the tools' capabilities or qualities (for this, the reader has to visit the provided vendor's website). Finally, most of the sample scenarios discussed in the book pertain to performance testing in Windows environments; while this won't matter to most readers because the principles discussed are equally applicable to other OS environments, this may matter to some readers who do not work with Windows environments at all.The Art of Application Performance Testing: Help for Programmers and Quality Assurance Overview
This practical book provides a step-by-step approach to testing mission-critical applications for scalability and performance before they're deployed -- a vital topic to which other books devote one chapter, if that. Businesses today live and die by network applications and web services. Because of the increasing complexity of these programs, and the pressure to deploy them quickly, many professionals don't take the time to ensure that they'll perform well and scale effectively. The Art of Application Performance Testing explains the complete life cycle of the testing process, and demonstrates best practices to help you plan, gain approval for, coordinate, and conduct performance tests on your applications. With this book, you'll learn to:

Set realistic performance testing goals
Implement an effective application performance testing strategy
Interpret performance test results
Cope with different application technologies and architectures
Use automated performance testing tools
Test traditional local applications, web-based applications, and web services (SOAs)
Recognize and resolves issues that are often overlooked in performance tests

Written by a consultant with 30 years of experience in the IT industry and over 12 years experience with performance testing, this easy-to-read book is illustrated with real-world examples and packed with practical advice. The Art of Application Performance Testing thoroughly explains the pitfalls of an inadequate testing strategy and offers you a robust, structured approach for ensuring that your applications perform well and scale effectively when the need arises. "Ian has maintained a vendor-agnostic methodology beautifully in this material. The metrics and graphs, along with background information provided in his case studies, eloquently convey to the reader, 'Methodology above all, tools at your discretion...' Ian's expertise shines through throughout the entire reading experience." -- Matt St. Onge, Enterprise Solution Architect, HCL Technologies America / Teradyne

Web Operations: Keeping the Data On Time ReviewThe answers aren't always simple and the multi-author nature of the book means that the structure is not straightforward, but the book contains most of the questions that Internet application developers and maintainers should ask themselves regarding operations, monitoring, backups, and scaling. The book pours cold water on one of my cherished ideas, i.e., build an Internet application as a relational database management system application and then add a thin HTML layer on top. But the authors and the experience of popular sites such as Facebook argue in favor of relegating the database to a very simple supporting role.Web Operations: Keeping the Data On Time Overview
A web application involves many specialists, but it takes people in web ops to ensure that everything works together throughout an application's lifetime. It's the expertise you need when your start-up gets an unexpected spike in web traffic, or when a new feature causes your mature application to fail. In this collection of essays and interviews, web veterans such as Theo Schlossnagle, Baron Schwartz, and Alistair Croll offer insights into this evolving field. You'll learn stories from the trenches--from builders of some of the biggest sites on the Web--on what's necessary to help a site thrive.

Learn the skills needed in web operations, and why they're gained through experience rather than schooling
Understand why it's important to gather metrics from both your application and infrastructure
Consider common approaches to database architectures and the pitfalls that come with increasing scale
Learn how to handle the human side of outages and degradations
Find out how one company avoided disaster after a huge traffic deluge
Discover what went wrong after a problem occurs, and how to prevent it from happening again
