PeopleSoft PeopleTools Tips & Techniques (Osborne ORACLE Press Series) ReviewThis is hands down the best book available for advanced PeopleSoft programmers. Each chapter builds upon the one before so it's very much a training guide as well as a reference manual. The great thing is that once you reach the end of it (no I haven't yet, I'm still working through it) you'll have some really nice bits of code you can use. The chapter on AWE (Approval Workflow Engine) was particularly well done I thought.
If you work on PeopleSoft software professionally and are serious about development you should really have this book in your collection. It opened a whole new world of possibilities for me and I've been using PeopleSoft for many years.
Here are some more observations:
1) To get the most out of this book you should have access to a PeopleSoft database that you can try things out on. It is heavily based on teach-by-example where concepts are introduced and then reinforced by code that you create and run in PeopleSoft. Actually typing the code for yourself will strengthen your understanding of the concepts presented as well as give you visual feedback.
2) A lot of the book covers Java, JavaScript and AJAX integrations into PeopleSoft. The author assumes that you already know these languages and does not attempt to teach them to you, other than at a very high level. So don't buy this book expecting to learn those languages.
3) If you are new to PeopleSoft development you won't get much out of this book. The target audience here is the seasoned PeopleSoft developer.
4) Many of the topics introduced are not documented anywhere else - at least to my knowledge. This makes the book particularly valuable in my view.
5) If object based PeopleCode is something new to you then I would get this book for that alone. It's covered very nicely.
I wish the Kindle version was available when I bought it but, oh well :-)PeopleSoft PeopleTools Tips & Techniques (Osborne ORACLE Press Series) Overview

Programming Microsoft Dynamics NAV ReviewThis book is aimed at people with some programming and business background, who plan to find their way into a NAV System. This is a challenging task, because NAV works somewhat differently to other ERP-Systems, and the author has done a good job in easing the way into a very complex application.
A simple sample application for a fictitious company is developed throughout the book. All objects ( Tables, Forms, Reports, Dataports, XMLPorts, Codeunits, MenuSuites) are first explained in their basic functions and properties, and later in more detail to implement the more advanced functions for the addon. A few of the major management codeunits which offer callable functions which every developer will look for sooner or later are covered, and by studying the way these codeunits are used the NAV newcomer will soon be able to write his own functions and subsequently his own enhancements.
Yet no one should be led to believe that after reading this book you can be let loose on any NAV System to do whatever you like. It takes a considerable amount of time to learn to estimate what impacts your coding will have in the long run, and even after several years there is always something new to learn, to fix or to optimize practically every day in an application that is making rapid strides forward. This applies even more so if you plan to work on many different databases which may have been extensively customized. But if you work your way through this book, and also take a good and hard look at the recommended internal documentations and white papers available, you will get a rough idea of what is lying ahead of you.
Of course there are quite a number of advanced topics on which you will find only a brief introduction in this book, such as the possibilities of interactions with external programs, the use of the NAV application server or automation objects (e.g. exporting/importing data to/from Excel).

A very useful comparison of the differences between the native server and SQL Server is also included. Locking, Deadlock and SQL Performance issues are discussed to some extent, but not to a degree that code examples of "do's and don'ts" are included.
There are some minor issues which I have found:
Page 246 : Although temporary tables run on the clients RAM only, all record variables in this table which are not temporary can insert, modify or delete data in the database. A seemingly harmless validate in a field trigger can lead to unexpected sideeffects. This is not mentioned.
Page 142/152 : The form triggers and form control triggers are listed ,and the author states that it should be avoided to write code in these triggers. Although this is basically true, the newcomer will find lots of code in standard forms, and will have a hard time in understanding the form and table interactions at first. Every card form needs a code line to remove the filter on the primary key, otherwise the user cannot move to the next record when the card form is called from a list form. This is not explained. Rather than removing code unnecessarily, this should be modified, as the new page object which will be introduced with NAV 2009 will have mostly an equivalent to the old form triggers as well, so it is advisable to only call functions in codeunits to avoid maintaining two similar functions in two objects.
Page 237 : It is not mentioned that a customer without the application designer granule, which small-size companies usually do not purchase, cannot import objects in .txt format. It is stated that only experienced developers should use the 2 merge options when importing .fob objects. In my opinion, this should be avoided at all costs unless any fields in the standard range have to be added which can't be created with a normal developers license when the object is of the .txt type. Then you have no choice and should perform a manual merge of the code afterwards to ensure that the code lines have not been messed up.
Page 121 : The examples for date and boolean for the AND operator are repetitions of the Not Equal operator examples.
Page 301 : Some examples of the FORMAT function would be useful. If you look for this in the index, you will find it under D (data conversion functions), not under F.
Page 345 : It is stated that Codeunits 80/90 post journal data into a ledger, but these Codeunits post Documents by transferring the data to journals, which are then posted by Codeunit 12 (G/L Ledger)/22 ( Item Ledger) etc.
Page 439 : It is stated that an executable upgrade is a one-way process. Actually, there is a backdoor if it fails, you can create an empty database with the old client, and then restore a .fbk backup which was created before installing the new executeables. A full upgrade, on the other hand, really is a one-way process.
