This paper is the result of a personal investigation on Business Rules (BR). Last year, when I presented a paper about a custom solution for the documentation and coding of BR, I thought I knew enough about them. Then, I began to investigate a bit more, and I discovered that there was much more than I thought. But then, the search wasn't easy. There were resources, for sure, but not any easy spot that covered everything I wanted to know. So I decided it would actually be good to try to have some resource of this kind, that would help whoever wanted to know that same information to achieve it easier and faster. So, this is what this paper is about: the general ideas on BR, the products, articles, authors, books, technologies, and bits and bouts I found and was able to put here. I warn you reader: now I know there is even much more to know! So, this paper is not perfect, and for sure not really up to its title! It is my personal vision of it all, and it probably has its share of mistakes in it. I apologize in advance if I don't render the authors or products as they really deserve. Let it be said that this is just and only the result of my personal investigation, most of it from over the internet, at night times, without direct contacts with the products or practitioners, expressed in my own way, and that it must be read and taken in account as such. I hope you find it helpful and enjoy it.
