About Omnis Studio

Omnis Studio is a high-performance visual RAD tool that provides a
component-based environment for building Web and enterprise, client/server
applications. Its Web Client plug-in technology allows server-based
applications to be accessed over the Internet using popular Web-browsers,
giving fast, secure, scalable solutions in a minimum of development time.
With complete scalability from individual to enterprise level solutions,
Omnis applications can be developed on any one supported platform and
deployed on any other platform without modification. Supported platforms
include, Windows XP and Vista, Mac OS X, and Linux, with full Unicode
support. Omnis directly supports traditional SQL databases such as MySQL,
PostgreSQL, Oracle, Sybase, and DB2, as well as TigerLogic's advanced
multidimensional database, D3, via the mvDesigner product. Most other
databases may be accessed via JDBC or ODBC. Omnis Studio dramatically cuts
application development time compared to 3GL environments (C++, Java), while
allowing the developer to use objects developed in 3GL environments as
components in Omnis applications.
