About 50,000 people are expected at the Oracle OpenWorld 2011 Conference, beginning Sunday at the Moscone Center in San Francisco.

Expectations are also high in other respects because of Oracle's entry into the hardware industry through its purchase of Sun Microsystems last year and because the company is closing in on $40 billion in annual revenue.

The Oracle OpenWorld will showcase the latest developments in security, governance, datacenter efficiency, and other top-level concerns. Through presentations and hands-on sessions, the conference offers hundreds of opportunities to learn money-saving techniques.

The who's who of the Oracle ecosystem is available at Oracle OpenWorld.

The company has stated in the letter of invitation that the attendees will get an expert-led experience of Oracle Application Development Framework, service-oriented architecture, application grid, Oracle WebLogic Server, rich enterprise applications, .NET, PL/SQL, Oracle Database, and the Oracle Solaris operating system.

Also, attendees will get an opportunity to learn new ways to extend and customize Oracle applications, including Oracle Fusion applications. They will get up-to-date information on Oracle's latest database technologies, including Oracle Database 11g and MySQL, and can discover the best ways to embed collaboration and social-computing capabilities with enterprise applications.

The sessions include presentations on Oracle's workload-optimized infrastructure products and solutions, which eliminate huge amounts of information-technology labor while improving performance, availability, security, and management.
