Features of the DQAF Measurement Logical Model

The purpose of this chapter is to describe features in the DQAF measurement logical data model (LDM) that are common to many of the measurement types and to provide general information related to the structure of tables that define specific measurements using DQAF measurement types and store measurement results. It discusses optional fields that might be included in these tables and describes additional features of a system to automate in-line data quality measurement. The chapter presents relatively dense, technically-oriented material. It should be read in conjunction with Chapters 15 and 17.
