Abstract : This paper proposes a definition of data "grain" for data protection in a relational model representation. The definition is based on previous research on data representation in a relational database using first order logic. The "grain" is the t-uple which is bind to a protection attribute, while other choices need to bind a protection level to each relation attribute value.
