I am attempting to categorize the use of databases by web applications, and looking to make a list of "parameters" to consider in such a taxonomy.<p>For example:<p>- size of data
- schema: rigid vs. flexible
- response time: micro-second, ... hours, ... days
- query language vs. API
- standard query encapsulation (xDBC) vs. API
- single <table> queries vs. joins
- the number of tables
- the kind of schema (single table, star, snowflake etc.,)<p>and so on.<p>Could you please help by visiting the google-document at http://tinyurl.com/2ewmy8w and submit your suggestions.<p>Thanks!
