Abstract: Some embodiments provide techniques of enforcing valid data assignments in a data processing system in which data can be dynamically updated by user devices and/or computerized processes. The techniques identify, using a validation rule associated with a data entity, one or more valid values for assignment to an attribute of an instance of the data entity. The techniques identify the valid value(s) by generating a query for the one or more valid values using one or more condition(s) on the attribute in the validation rule, and executing the generated query to obtain the one or more valid values for the first attribute. The attribute may then be assigned one or more of the identified valid value(s).

Abstract: The present invention is directed to a composition curable by radiation having a wavelength of 300 nm or more, a method of producing a coated substrate using such composition and the coated product so-produced. More particularly, the composition of the present invention comprises A) from about 1 to about 99% by weight of an unsaturated polymer or oligomer, B) from about 1 to about 99% by weight of an unsaturated epoxy acrylate, C) one or more photoinitiators, and, optionally, D) one or more solvents.
