With the release of Office 2007 and the whole enterprise suite, there seems to be a lot more buzz on the net about creating Office Business Applications (OBAs) to integrate enterprise business. This integration revolves around the idea of the ESB, which of course Biztalk seems to be the best implementation of it. IMHO. ;)
Developing in Sharepoint 2007, Infopath 2007 and Biztalk 2006 seems to fall into this category. There is a book written that Microsoft has made available for free download. Here is the link to Mike Walker's blog. He is one of the authors of the book. You can download the book here.
According to his blog, the LOB (Line Of Business) for loan originations will be out pretty soon. And this LOB will contain all of the files needed to implement the Loan Origination Solution. Including guidance package, enterprise blocks, etc. Nice. I can't hardly wait to start playing with this.
I like how Microsoft is leading the way by providing Best Practices (Enterprise Library) and Guidance Packages(GAX) that developers can follow when implementing enterprise solutions that have reusability and extensibility.
