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 are in compliance with the ANSI standard.
This enables Opinio to support databases like Oracle, Microsoft Sql
Server, DB2, PostgreSQL, MySql and others.
- 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. Apache Derby (default), Oracle, MS Sql server, IBM
DB2, MySql, and Postgres are supported.
