Refactoring – Documentation – Software Framework

Hello dear readers. In this blog post I would like to write about Refactoring, documentation and software framework. While explaining what they are I will try define why are they needed.

Refactoring is very used term in software development and has played a major role in the maintenance of software. Refactoring is one of the most self-evident processes, but it is surprisingly difficult to perform properly. In most cases, we deviate from strict refactoring and execute an approximation of the process; sometimes, things work out and we are left with cleaner code, but other times, we get snared, wondering where we went wrong. In either case, it is important to fully understand the importance and simplicity of barebones refactoring. Refactoring is a controlled technique for improving the design of an existing code base. Its essence is applying a series of small behavior-preserving transformations. The cumulative effect of each of these transformations is quite significant. By doing them in small steps you reduce the risk of introducing errors. You also avoid having the system broken while you are carrying out the restructuring — which allows you to gradually refactor a system over an extended period of time.

I also want to talk about documentation in this blog post. For a programmer reliable documentation is always needed. The presence of documentation helps keep track of all aspects of an application and it improves on the quality of a software product. Its main focuses are maintenance, development, and knowledge transfer to other programmers. Successful documentation will make information easily accessible, simplify the product, help new users learn quickly, provide a limited number of user entry points and help cut support costs. Documentation is usually focused on the following components that make up an application: business rules, troubleshooting, server environments, application installation, database/files and code deployment.

A software framework is a concrete platform where common code with general functionality can be specialized or overridden by developers or users. Frameworks take the form of libraries, where a well-defined API is reusable anywhere within the software under development. There exist some features that make a framework different form other library form. These features are: default behavior, inversion of control, extensibility, non-modifiable framework code.

I am attaching the following links that will help you have a better understanding of these concepts as these blog posts also provide examples.
