Validation

Application of validation rules to the data helps to ensure that data is valid and reliable, making databases consistent, functional, and providing reliable value to their users. OS.bee provides validation separated from application layer or domain model, based on JSR303 specification.

Designtime

Layer independent

Implement it at various levels (data collection, compilation, data entry, data processing and analysis).

Separated

Avoid cluttering domain classes with validation code.

Framework

Utilize JSR defined metadata model and API for JavaBean validation.
