Question 1:
SQL is a standard that most developers know, and most open
source relational databases implement in a consistent manner.
How are the no-SQL offerings going to provide a more
consistent and productive for software developers?
What benefits are there for not using SQL in development?
Brian Aker is not allowed to re-use Lightning talk material.

Question 2:
SQL databases have many open source products and offerings
available via the LAMP stack, including popular blogging,
wiki and Content Management (CMS) software (for example
Wordpress, Drupal, Mediawiki etc )
With the newer non relational products now available what is
the ideal industry segment or products (new and proposed) that
will be of benefit for every day people?
What products won't work with no-SQL technologies?

S
Question 3:
Scalability and high availability with relational databases can
really suck. This requires a great amount of planning and
architecture to implement successfully in large scale
environments.
What are the strengths you can offer towards the needs for
read scalability, write scalability, software upgrades and
database maintenance without impacting the user experience?

Question 4:
Transactions form an essential component in many business
critical systems including financial and military.
How does my bank balance work in an eventually consistent
environment?
While many systems can survive without the need of database
centric consistency, many developers need greater education.
How do you educate them for what is best?

Question 7:
Can SQL and noSQL co-exist happily in one software product
offering?
Can one be used as meta data or caching for the other?
Is data interchangable?
Are there any benefits of working together?
Are there any arguments for never working together?

Question 8:
A great product with a great code base can easily go the way of
the dodo if there is not a supportive and active community.
What are each product group doing to better gain, retain and
utilize the community for maximum benefit?
What do you do that other products should?
What do other products do that you wish you did?

Wrap-up
Open SQL Camp - Portland 2009 http://opensqlcamp.org #opensqlcamp

SQL and no-SQL
are really poor
descriptions
Open SQL Camp - Portland 2009 http://opensqlcamp.org #opensqlcamp

Relational and non
relational.
Is RDBMS and AltDB a
better description.
