The problem is to successfully create a Database Refactoring Framework for databases. Refactoring has proven its value in a wide range of development projects—helping software professionals improve system designs, maintainability, extensibility, and performance. Most of it seemed like common sense to me. Now, for the first time, leading agile methodologist Scott Ambler and renowned consultant Pramodkumar Sadalage introduce powerful refactoring techniques specifically designed for database systems. Databases usually contain Data (stored according to a schema) Stored code Stored code is no different from any other code except that it runs inside of a database Database schema Data is the state of a database Maintaining the state needs a different approach from refactoring the code The goal of this work is the definition of refactoring rules to support the management of the evolution of Graph Databases by adapting and extending existent refactoring rules for relational databases to meet the requirements of the Graph Databases features. Refactoring has proven its value in a wide range of development projects-helping software professionals improve system designs, maintainability, extensibility, and performance.
