Study Cases Howto

= Procedure =
The following procedure should be followed by people completing a case study.
The goal is to ensure maximum efficiency and that the person being case studied
is not frustrated by the process.
So, as a first step ensure that you send the company a list of case study questions.
Supplement them if you think the company's situation warrants it.
Once you've received the answers to the questions, form it into a case study as follows:
* Background on who the company is
* What they are trying to do
* How their application achieves it, useful technical details particular about how PostgreSQL has helped them achieve it
Write a short conclusion 
* This should be interspersed with quotes from the company
* Be sure to get images, titles of the people you are quoting
Once you've written a draft; re-read it, write and pay particular attention to writing style. If you are uncertain about grammar -- and I believe most people should be -- please refer to a simple English language style guide, such as: http://andromeda.rutgers.edu/~jlynch/Writing/
Once you have read it, checked for spelling, etc., forward it to another person on the project to read. Once they have done this and you're happy, forward to the company for permission on the text.
Then forward to "Name to be added" <email@to.be.added> for layout. You will receive the case study back in a draft layout. This needs to be approved by the company.
Once approved, upload to the press module on pgfoundry and mark ready for publishing.

=== Application specific questions ===
To provide useful information to readers, it would be good to look at specific applications. Please answer the following for each application you would like me to write about (limit to 4).
23) Broadly speaking, what does the application do? What problem does it solve? Please provide a thorough description of the architecture with detail which technical readers will find interesting.

*(b) by customers/clients who purchase a copy/license and run it on their own systems 
*(c) by customers/clients but hosted on your systems 
*(d) a combination of the above/other (please detail)?
25) How many users does the application serve?
26) Does your organisation need to meet a service/availability/performance level with this application? For example, it must be available 99.999% of the time; it must be available to up to 200 users at a time; the response time of the application must not exceed 800ms, etc.
27) What language(s) is your application written in?
28) If any, what other software packages are used as a component of the application? For example, the Apache web server; a J2EE application server, etc.
29) Approximately how long has the application been in development?
30) Approximately how many lines of code makes up the application?
31) When selecting a database for the application:
*(a) Which database systems were considered?
*(b) Why did your organisation select PostgreSQL? or,
*(c) If the application was originally using another database system, why did you migrate to PostgreSQL? How did this affect the TCO for you/your customers?
32) What features of PostgreSQL does your application rely on most heavily? For example, transaction throughput, scalability, data integrity, etc.
33) If applicable, how has PostgreSQL enhanced the quality of your application?
=== General impressions of PostgreSQL ===
34) Has your organisation found PostgreSQL to be reliable?
35) Has your organisation found PostgreSQL to be a viable alternative to other open and closed source applications?
36) Has your organisation been able to more easily solve problems with PostgreSQL due to its being open source? For example, have you contributed a bug fix or feature enhancement?
37) Has your organisation benefited from the community surrounding PostgreSQL in a way it would not/may not have benefited if you used a different database system?
38) Any other comments about PostgreSQL? In particular, remarks which sum up the experience you've had with PostgreSQL and how it has enhanced your application(s) and your business.
