DeepakVohra commented on CASSANDRA-15481:
-----------------------------------------

[~rustyrazorblade] I would suggest keeping the index.rst page 
(https://github.com/Deepak-Vohra/cassandra/blob/data_modeling/doc/source/data_modeling/index.rst)
 I added as the first page of the documentation. And keep the *elaborate 
example* (http://cassandra.apache.org/doc/latest/data_modeling/index.html) from 
O'Reilly book as subsequent pages. I have discussed the important concepts 
though the example is not real-world and not too detailed. I would like to get 
opinion of other reviewers including from [~zznate]and [~djoshi]  before you 
resolve the ticket. Could you reopen the ticket?

The O'Reilly book chapter posted as documentation makes use of a *great 
example*, which I would suggest keeping, but has several issues:

1. It starts right-away with an example from the first statement, "First, let’s 
create a simple domain model that is easy to understand in the relational 
world, and then see how you might map it from a relational to a distributed 
hashtable model in Cassandra.", without discussing concepts. 

1. Does not define what data modeling is. I have defined data modeling in "What 
is Data Modeling?".

2. Does not discuss some important concepts such as 
_Single table-single query_ approach, which I have discussed in 
"How does Apache Cassandra Model Data?"
 
3. Does not discuss how queries are selected, which I have discussed in 
"Selecting Queries to Support".

4. Does not compare with relational model, which I have in section "Comparing 
with Relational Data Model".

5. Does not discuss data model analysis such as _Data redundancies_, which I 
have discussed in "Data Model Analysis". 

6. Does not discuss materialized views albeit as an experimental feature.
