Opinio is a comprehensive system to create, publish, analyze and
maintain surveys. With java/servlets at its base, it is a platform
independent, robust and scalable survey system.
Opinio is designed to be:
-
Platform/OS independent. The use of
Java/servlets makes this possible.
-
Database independent. All database
interaction follows ANSI standard. It is easy to use other
databases than what is included. See other databases.
-
Client independent. The administration module is
designed as a web-based interface, but the survey module
is designed to handle any type of client. A web based survey
module has been implemented, and new client types will be
added soon (WAP, PDAs, Email, phone, etc).
-
Language independent. New languages are
very easy to add.
Opinio stores all its information in a central database; surveys,
responses to surveys, admin users and access rights - all stored in one
single place. Opinio does not require a specific database engine.
Oracle, MS Sql server, Hypersonic SQL, and MySql are supported, and more will be added.
