Easy Business Rules

OpenL Tablets targets the infamous gap between business requirements (rules and policies) and software implementation.

Keeping in mind the need to be simple and intuitive for business people OpenL Tablets made its rules representation impressively close to documents usually created by business.

Users can feel relieved and concentrate on logic as all data, syntax and type errors are checked while authoring. Convenient tools help to insure rules integrity while maintenance.

One-click deployment of rules as efficient, scalable and standardized services for SOA-based integration makes business logic simple to consume in your application.

For Java developers OpenL Tablets provides many rich usage scenarios where all rules and business data are exposed through reflection-like API or wrapped as Java class.

All of OpenL Tablets is open sourced under LGPL license.
