In the 1970s, Codd laid out a plan for improving programmer productivity and accelerating systems development by improving the management and processing of data. Learning Objectives. In this chapter, you will learn:. That the relational database model offers a logical view of data. About the relational model’s basic component: relations. That relations are logical constructs composed of rows (tuples) and columns (attributes).
