What is maintainability in programming?

Software maintainability is defined as the degree to which an application is understood, repaired, or enhanced. Understanding software maintainability allows organizations to identify improvement areas as well as determine the value supplied by current applications or during development changes.

What is maintainability in Java?

The ease or difficulty with which a software system can be modified is known as its maintainability. The maintainability of a software system is determined by properties of its source code.

What is extensibility in OOP?

Extensibility is a software engineering and systems design principle that provides for future growth. Extensibility is a measure of the ability to extend a system and the level of effort required to implement the extension.

What is maintainability why the need of it?

Maintainability is considered, inherent to the building system design, ensuring the ease, accuracy, safety, and economy of maintenance tasks within that system. The purpose of maintainability is to improve effectiveness and efficiency of maintenance.

What is the meaning of maintainability?

Maintainability is the measure of the ability of an item to be retained in or restored to a specified condition when maintenance is performed by personnel having specified skill levels using prescribed procedures and resources at each prescribed level of maintenance and repair.

What is a maintainable code?

To a developer, maintainable code simply means “code that is easy to modify or extend”. It is code that is instrumented and easy to troubleshoot, where any anomalous conditions within the application are logged, even if they don’t cause errors.

Is OOP easy to maintain?

OOP makes it easy to maintain and modify existing code as new objects can be created with small differences to existing ones. OOP provides a good framework for code libraries where supplied software components can be easily adapted and modified by the programmer.

How do I create a Keepable software?

Building Maintainable Software

1. Write short units of code: limit the length of methods and constructors.
2. Write simple units of code: limit the number of branch points per method.
3. Write code once, rather than risk copying buggy code.
4. Keep unit interfaces small by extracting parameters into objects.

What is code flexibility?

The flexibility of your code is defined by the ease with which you can modify it to fulfill some purpose you hadn’t envisaged at the time you wrote it. It’s quicker to read and understand code with fewer syntactic elements, such as variables, functions and classes. It’s also quicker to repurpose.

What is reusability in OOP?

Reusability: Inheritance supports the concept of “reusability”, i.e. when we want to create a new class and there is already a class that includes some of the code that we want, we can derive our new class from the existing class. By doing this, we are reusing the fields and methods of the existing class.

What is coupling and cohesion?

” Coupling ” describes the relationships between modules, and ” cohesion ” describes the relationships within them. This means that in a good design, the elements within a module (or class) should have internal cohesion.

What are the measures of maintainability?

The proposed model measures the software maintainability based on three important aspects of software-readability of source code (RSC), documentation quality (DOQ), and understandability of software (UOS). Keeping in view the nature of these parameters, a fuzzy approach has been used to integrate these three aspects.
