Refactoring is usually motivated by noticing a code smell. [2] For example, the method at hand may be very long, or it may be a near duplicate of another nearby method. Once recognized, such problems can be addressed by refactoring the source code, or transforming it into a new form that behaves the same as before but that no longer "smells".
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
Examples of refactoring: moving code to where it most logically belongs; removing duplicate code; making names self-documenting; splitting methods into smaller pieces; re-arranging inheritance hierarchies; Repeat Repeat the process, starting at step 2, with each test on the list until all tests are implemented and passing.
A decomposition paradigm in computer programming is a strategy for organizing a program as a number of parts, and usually implies a specific way to organize a program text.

Rule of three ("Three strikes and you refactor") is a code refactoring rule of thumb to decide when similar pieces of code should be refactored to avoid duplication. It states that two instances of similar code do not require refactoring, but when similar code is used three times, it should be extracted into a new procedure.
A database refactoring is a simple change to a database schema that improves its design while retaining both its behavioral and informational semantics. Database refactoring does not change the way data is interpreted or used and does not fix bugs or add new functionality. Every refactoring to a database leaves the system in a working state ...
The focus is on refactoring the service in smaller steps so that the impact of each step is minimal and can be easily reversed if it negatively affects the service consumers. Secondly, to ensure the service contract remains unaffected by changes in logic or implementation, the service contract must be decoupled as much as possible. [ 5 ]
