This paper focuses on data modeling for traceability of material/work flow in information
layer of manufacturing control system. The model is able to trace all associated data throughout the
product manufacturing from order to final product. Dynamic data processing of Quality and Purchase
activities are considered in data modeling as well as Order and Operation base on lots particulars. The
modeling consisted of four steps and integrated as one final model. Entity-Relationships Modeling as
data modeling methodology is proposed. The model is reengineered with Toad Data Modeler software
in physical modeling step. The developed model promises to handle fundamental issues of a
traceability system effectively. It supports for customization and real-time control of material in flow
in all levels of manufacturing processes. Through enhanced visibility and dynamic store/retrieval of
data, all traceability usages and applications is responded. Designed solution is initially applicable as
reference data model in identical lot-base traceability system
