Question about The Data Model Resource Books

[Luis Uribe-2]

Hi all,

We're developing a small ERP-like system, with PHP5 and postgreSQL.

We're making the data model based on the The Data Model Resource books, Vol 1
and 2. They have very good examples and a lot of information.

Aditionaly Wiley sells a CD-Rom (The Data Model Resource CD: A Library of
Universal Data Models for All Enterprises, Revised Edition) with the SQL code
to implement the models described in the book.

Hence, my question is: Anyone have this CD? Do you think it is worth buying
this CD or the books are just fine? Basically because we're a small startup
with a low budget :)

Thanks in advance

Luis,

If someone did have the CD it would not be legal for them to send it  
to you, and I don't think it would be legal to distribute a system  
based on the stuff on the CD if you had it.

The OFBiz data model is a clean room implementation based on the  
general concepts found in those books.

I'm sorry if my message was misunderstood. I don't want to get the cd for
free, i'm just asking for opinions of the people who had bought it.

I see, I thought that it was a modification of the models created in the book.
My mistake.

Thank You :)

I did actually consider the CDs originally to maybe save some work,  
but the license was scary so I decided to not even buy them or try to  
find their contents.

Of course, you could always just do something based on the OFBiz data  
model. If you run OFBiz against a database it can create tables with  
the Entity Engine meta data, and then you can reverse engineer those  
tables or generate the meta data SQL from them or something...
