ADM315 Workload Analysis | SAP Basis Books

Course Overview

ADM315 presents knowledge that you need for analyzing load situations in SAP systems. Most of the tools introduced here exist since a long time in SAP systems, some as early as SAP R/3 3.0. However, the layout of these tools and their capabilities evolved over time and new functions were introduced to monitor new components of SAP systems.

Even while this course takes place on the ERP Central Component system (ECC 5.0) of mySAP ERP 2004 and is based on an Oracle database and Windows operating system, almost all of the functions and skills learned here are as well applicable to releases of R/3 (as R/3 4.6C and SAP R/3 Enterprise, Extension Set 1.10/2.00) and to other SAP system types (SAP CRM systems, SAP SRM systems etc.) on different operating system and database platforms.

Indeed, the focus of this course is to give a detailed understanding on perfomance issues in SAP systems, which allows you to apply your skills to a wide range of SAP products.

Eclipse For Dummies | Barry Burd | PDF

Another one of the newer books out on Eclipse is Eclipse For Dummies by Barry Burd (Wiley). I like the book for what it is, but there are some caveats that may affect your experience... 

Chapter List:
Part 1 - The Eclipse Landscape: Reader, Meet Eclipse, Eclipse, Meet The Reader; Installing Eclipse; Using the Eclipse Workbench; Changing Your Perspective; Some Useful Perspectives and Views
Part 2 - Using the Eclipse Environment: Using the Java Editor; Getting Eclipse to Write Your Code; Straight from the Source's Mouse; More Eclipse "Sourcery"; Refactoring: A Burd's Eye View; Refactor This!; Looking for Things in All the Right Places
Part 3 - Doing More With Eclipse: Working with Projects; Running Code; Getting Help; Squashing Bugs
Part 4 - The Part of Tens: The Frequently Asked Questions (And Their Answers); Ten Great Plug-ins for Eclipse

First off, what I liked... I'm unapologetic in my liking of Dummies titles. They mesh well with my learning style (light and humorous), and I think they do a great job in giving one a good understanding of a particular subject. If you had never read anything about Eclipse, this book would be a good way to expose you to the functionality of the software. I also like how Burd covers the features of the software, like refactoring and such. Once again, when you get done with the book, you should understand how the software can help you when you're coding your programs. Finally, it's been published since Eclipse 3 was released, so it's dealing with the latest and greatest.

So what are the caveats? The book deals mostly with the Eclipse as an IDE, but not so much with actual coding with it. There are other books out there that largely cover the same material as this book does, but they have more of an emphasis on actual coding examples. Having the practical coding examples can help cement some of the learning you'll need going forward.

It's not that this book is bad or that it's done a bad job. It's just that depending on what you're looking for, this may or may not be your best choice...

Ajax For Dummies | PDF | Download Now

Ajax is obviously one of the hot web technologies these days, and now we have the Dummies title that covers it... Ajax for Dummies by Steve Holzner. While it might be easy to write this off as "just another Dummies book", I don't know that I'd be so hasty...

Part 1 - Getting Started: Ajax 101; It's All About JavaScript
Part 2 - Programming in Ajax: Getting to Know Ajax; Ajax in Depth
Part 3 - Ajax Frameworks: Introducing Ajax Frameworks; More Powerful Ajax Frameworks; Server-Side Ajax Frameworks
Part 4 - In-Depth Ajax Power: Handling XML in Ajax Applications; Working with Cascading Style Sheets in Ajax Applications; Working with Ajax and PHP
Part 5 - The Part of Tens: Ten Ajax Design Issues You Should Know About; Ten Super-Useful Ajax Resources

As I said, I wouldn't write this off as just another Dummies title. For one, Steve Holzner has an excellent track record of writing tech books that have become the go-to references in the industry. As per usual, he also does a great job on this book, albeit in the "Dummies" style of presentation and writing. There is an abundance of code and screen shots that make it easy to follow along, and he presents just enough background on JavaScript and other Ajax components to bring you up-to-speed if those are not your strong areas. The only "nit" I have is that some of the code and screen shots in Chapter 2 don't quite mesh. The code statements for what should be on the screen don't quite match what actually printed out. It's as if the screen shot was made with a slightly reworded JavaScript routine. It still is essentially the same, but it threw me slightly as I was going through the material.

I felt the book really came to life in Part 3 with coverage of the different frameworks. I don't think any of the other books I've read on Ajax to date have had quite this much information on all the different frameworks you can implement to eliminate much of the "heavy lifting". Since Steve does a good job of presenting the pros and cons of each, you'll quickly determine if a framework is the way you want to go, and which options might be best for your particular project.

While not the most technical book on the subject, Ajax for Dummies does bring some angles to the table that aren't present (or as strong) in other books. It'd be a good introduction to the subject matter, or a nice second volume to gain a different perspective on the technology.
