I was just reminded yesterday about a blog entry that I read early last year about the book Understanding DB2(R): Learning Visually with Examples. The entry was from James F. Koopmann. The statement that I found most interesting was this:
Now it has been close to 15 years since I worked with DB2 on MVS and have over the years wanted to pick up DB2 again. But having enough time to pull away from Oracle and all the projects I seem to be doing never really gave me the opportunity. Honestly I can say that I am glad I waited. If I would have started with any other book instead of Understanding DB2 I may have gotten discouraged.
One of the best parts of reading this book was that it went into just enough detail for experienced database practitioners to obtain a clear understanding of the components of DB2. Often I was able to easily relate my Oracle, and old DB2 experience, to the concepts in this book. This made learning even easier. This is no easy. I am not even sure that the authors of this book sought out to do. But I can tell you from experience that I have in the past tried to relate database systems, such as Oracle, DB2, SQL Server, and Sybase, together and it is not an easy task to find the information needed. This book cuts through the chase and quickly and easily points out the physical and logical components of DB2 that now allows me to do this.
One of our training courses that was created specifically for those trained on other relational databases has been recently update and is another good way to expand existing skills to include DB2: CF282 Fast Path to DB2 9 for Experienced Relational DBA * Classroom * 3 Days *
