SQL
The survey questionnaire and responses are stored in SQL databases. This provides
the highest level of flexibility, functionality, reliability, and accessibility. Data is
easily ported from the web to the SQL databases and back to the web as needed.
SQL is the most common standardized language used to access databases. The SQL server is a client/server system that consists of a multithreaded SQL server that supports different backends, several different client programs and administrative tools.
