Two styles of programming are encountered in the database world. Classical programming as taught in many universities leads to an atomic, row-oriented, and procedural style inspired by the structured models of programming. In short, many application developers write in the relational database exactly like in the user interface. The other style of programming is holistic, data set oriented, and coded mainly in SQL. This is the style of the database developer. The set based and holistic style of development is not promoted enough in universities, and many application developers are not fully aware of it. There are many performance issues all over the world in relational databases due to the use of the atomic and inappropriate style of programming. This book compares the two styles, and promotes the holistic style of development as the most suitable one. Examples are given to demonstrate the superiority of a set-based and holistic approach. About the Author About the Technical Reviewer Introduction Chapter 1: The Concept of Style Chapter 2: SQL: Beauty and the Beast Chapter 3: A Holistic Vision of the Data Chapter 4: Data by Set or by Row? Chapter 5: Data Transfer Paradigm Chapter 6: The Challenge of Scalar Functions Chapter 7: Writing SQL vs. Writing Procedurally Chapter 8: Row Triggers and the Need for Atomic Solutions Chapter 9: Final Reflections and Thoughts Index Learn the best way of writing code to run inside a relational database. This book shows how a holistic and set-oriented approach to database programming can far exceed the performance of the row-by-row model that is too often used by developers who haven't been shown a better way.
