| Refactoring is a disciplined way to restructure code when small changes are made to the code to improve its |
| design. An important aspect of a refactoring is that it improves the design while not changing the semantics |
| of the design; a refactoring neither adds nor removes functionality. |
| </p> |
| <p> |
| Refactoring enables you to evolve the code slowly over time, to take an iterative and incremental approach to |
| implementation. |
| </p> |
| <p> |
| These are the types of refactoring: |
| </p> |
| <ol> |
| <li> |
| Code refactoring. Often referred to simply as refactoring, this is the refactoring of programming source |
| code. Examples of code refactorings include Rename Method, Encapsulate Field, Extract Class, Introduce |
| Assertion, and Pushdown Method. |
| </li> |
| <li> |
| Database refactoring. A database refactoring is a simple change to a database schema that improves its design |
| while retaining both its behavioral and informational semantics. Examples of database refactorings include |
| Rename Column, Split Table, Move Method to Database, Replace LOB with Table, Introduce Column Constraint, and Use |
| Official Data Source. |
| </li> |
| <li> |
| User interface (UI) refactoring. A UI refactoring is a simple change to the UI which retains its |
| semantics. Examples of UI refactorings include Align Entry Fields, Apply Common Button Size, Apply Common |
| Font, Indicate Format, Reword in Active Voice, and Increase Color Contrast. |
| </li> |
