SQL and Email Business Rules, Stored Procedures with Output Caching

Code On Time release 6.0.0.27 introduces major new enhancements to the business rules processing and data retrieval.

It is now possible to create SQL Business Rules that can interact  with all tiers of a web application: database engine tier, application server tier, and client web browser tier. All of these are possible in a comfort of a familiar SQL dialect such as T-SQL or PL/SQL. Take a look at a validation example with SQL Business Rules. You can now develop and debug SQL Business Rules in your favorite tool and paste them as-is in the application definition. Use data controller virtualization to define SQL Business Rules at runtime with the node set plugins.
