A method for validating data in a hybrid cloud model that includes providing a validation layer in the brokerage module of the hybrid architecture. The validation layer is separate from an applications layer of the hybrid architecture. The method includes sending target object values to a centralized brokerage layer composite query generator (BLCQG) component of the validation layer from an application needing validation of target data time. The method continues with generating a composite validation rule set with the brokerage layer composite query generator (BLCQG) component based on the parameters of the target object values. The method further includes validating the target data item of the target object values with the composite validation rule in the validation rules validator (VRV) component; and sending the target data item that has been validated to the application.
